  • Using anchor property with dynamically added controls

    - by tcube
    I'm adding some textboxes to a form dynamically at runtime. Everything works fine i.e. the textboxes are aligned, anchored and automatically resizes until the form is maximized. On maximizing the form, the textboxes are added to the same location while the form was not maximized. This causes a misalignment of the textboxes. How can I ensure that all the textboxes are at the same location and of the same size both while the windowstate is normal as well as maximized? EDIT: Btw I'm using C# EDIT: Would a flowlayoutpanel be useful here?

  • Changing/Adding controls to the windows Open/Save common dialog

    - by ajp
    Is there a way of changing/adding to the windows Open/Save common dialog to add extra functionality? At work we have an area on a server with hundreds of 'jobfolders'- just ordinary windows folders created/managed automatically by the database application to house information about a job (emails/scanned faxes/Word docs/Spreadsheets/Photos etc) The folders are named by the job Number. I would like to expand the standard open/save dialog with a combobox which searches for jobfolders based on tags from the database, so that whatever my users are doing they can easily find their way to the correct jobfolder to find/save their work Connecting to the database and providing the functionality to search is no problem, but is there a way to add a combobox control (ideally with a keypress/keydown event) to the dialog? Or Create my own dialog and have it called/used in place of the standard one? i.e. from ANY app my dialog would be called allowing easy access to the jobfolders. If they are in outlook they can find a jobfolder quickly, if there are using Notepad they can still find the folder easily. This would mean a new unified way of finding jobfolders from any app. Ideally someone would know a way using VB/VB.net/C# but I'm guessing, if its possible, its probably going to be C++.

  • Substitute User Controls on Failure

    - by Brian
    Recently, I had a user control I was developing throw an exception. I know what caused the exception, but this issue got me thinking. If I have a user control throw an exception for whatever reason and I wish to replace that usercontrol with something else (e.g. an error saying, "Sorry, this part of the page broke.") and perhaps log the error, what would be a good way to do it that could be done independently of what the user control is or does (i.e. I'm not saying what the user control does/is, because I want an answer where that is irrelevant). Code sample: <asp:TableRow VerticalAlign="Top" HorizontalAlign="Left"> <asp:TableCell> <UR:MyUserControl ID="MyUserControl3" runat="server" FormatString="<%$ AppSettings:RVUC %>" ConnectionString="<%$ ConnectionStrings:WPDBC %>" Title="CO" /> </asp:TableCell> <asp:TableCell> <UR:MyUserControl ID="MyUserControl4" runat="server" FormatString="<%$ AppSettings:RVUA %>" ConnectionString="<%$ ConnectionStrings:WPDBA %>" Title="IEAO" /> </asp:TableCell> </asp:TableRow>

  • Sharepoint Web Part validation set off by Publishing Controls

    - by dunxd
    I have a web part which uses validation on a textbox field to prevent submission of an empty field. When clicking on Check In to Share Draft or Publish, this validation is done, and since I am not actually trying to submit the form, but rather check it in, I'd rather this didn't happen. How can I achieve this? See also: Sharepoint web part form validation blocks updating web part settings - this has the validation code, and how I solved the problem of the EditorPart setting off the validation.

  • What is a good alternative to the WPF WebBrowser Control?

    - by VoidDweller
    I have an MDI WPF app that I need to add web content to. At first, great it looks like I have 2 options built into the framework the Frame control and the WebBrowser control. Given that this is an MDI app it doesn't take long to discover that neither of these will work. The WPF WebBrowser control wraps up the IE WebBrowser ActiveX Control which uses the Win32 graphics pipeline. The "Airspace" issue pretty much sums this up as "Sorry, the layouts will not play nice together". Yes, I have thought about taking snapshots of the web content rendering these and mapping the mouse and keyboard events back to the browser control, but I can't afford the performance penalty and I really don't have time to write and thoroughly test it. I have looked for third party controls, but so far I have only found Chris Cavanagh's WPF Chromium Web Browser control. Which wraps up Awesomium 1.5. Together these are very cool, they play nice with the WPF layouts. But they do not meet my performance requirements. They are VERY HEAVY on memory consumption and not to friendly with CPU usage either. Not to mention still quite buggy. I'll elaborate if you are interested. So, do any of you know of a stable performant WPF web browser control? Thanks.

  • Dynamically loaded control - how can I access a value in Page_Init

    - by Sam
    I am loading a LinkButton dynamically when a user clicks on another LinkButton. I am attaching an event handler to it. When the user clicks on the dynamically loaded LinkButton, the event does not fire. From what I've been reading, I understand this is because when the page posts back the dynamically loaded control no longer exists. It looks like I'm supposed to make sure this control is recreated in Page_Init. The dynamically created LinkButton is dependedent on a value (Product ID). I need someway to access this value so I can properly create the control. ViewState is not accessible and I'm concerned if I use Session it could time out and then that wouldn't help. Any ideas? Also, I hardcoded a Product ID value just for testing, and that still did not cause the event to fire. Is there something else I need to do? protected void Page_Init(object sender, EventArgs e) { SetTabText(1, 1); } SetTabText calls SetActionLinks which creates the LinkButton: protected Panel SetActionLinks(int prodID, int tabID) { ... LinkButton lnkBtn = new LinkButton(); lnkBtn.ID = "lnkBtn" + rand.Next().ToString(); lnkBtn.CommandName = "action"; lnkBtn.Command += new CommandEventHandler(this.lnkAction_Command); panel.Controls.Add(lnkBtn); ... } void lnkAction_Command(object sender, CommandEventArgs e) { LinkButton btn = (LinkButton)sender; switch (btn.CommandArgument) { AddCart(); } }

  • GDI RoundRect on Compact Framework: make rounded rectangle's outside transparent.

    - by VansFannel
    Hello! I'm using the RoundRect GDI function to draw a rounded rectangle following this example: .NET CF Custom Control: RoundedGroupBox Because all controls are square, it also draw the corners outside of the rounded rectangle. How can I make this space left outside the rectangle transparent? The OnPaint method is: protected override void OnPaint(PaintEventArgs e) { int outerBrushColor = HelperMethods.ColorToWin32(m_outerColor); int innerBrushColor = HelperMethods.ColorToWin32(this.BackColor); IntPtr hdc = e.Graphics.GetHdc(); try { IntPtr hbrOuter = NativeMethods.CreateSolidBrush(outerBrushColor); IntPtr hOldBrush = NativeMethods.SelectObject(hdc, hbrOuter); NativeMethods.RoundRect(hdc, 0, 0, this.Width, this.Height, m_diametro, m_diametro); IntPtr hbrInner = NativeMethods.CreateSolidBrush(innerBrushColor); NativeMethods.SelectObject(hdc, hbrInner); NativeMethods.RoundRect(hdc, 0, 18, this.Width, this.Height, m_diametro, m_diametro); NativeMethods.SelectObject(hdc, hOldBrush); NativeMethods.DeleteObject(hbrOuter); NativeMethods.DeleteObject(hbrInner); } finally { e.Graphics.ReleaseHdc(hdc); } if (!string.IsNullOrEmpty(m_roundedGroupBoxText)) { Font titleFont = new Font("Tahoma", 9.0F, FontStyle.Bold); Brush titleBrush = new SolidBrush(this.BackColor); try { e.Graphics.DrawString(m_roundedGroupBoxText, titleFont, titleBrush, 14.0F, 2.0F); } finally { titleFont.Dispose(); titleBrush.Dispose(); } } base.OnPaint(e); } An the OnPaintBackground is: protected override void OnPaintBackground(PaintEventArgs e) { if (this.Parent != null) { SolidBrush backBrush = new SolidBrush(this.Parent.BackColor); try { e.Graphics.FillRectangle(backBrush, 0, 0, this.Width, this.Height); } finally { backBrush.Dispose(); } } } Thank you!

  • Automatic linebreak in WPF label

    - by Vlad
    Dear all, is it possible for a WPF Label to split itself automatically into several lines? In my following example, the text is cropped at the right. <Window x:Class="..." xmlns="..." xmlns:x="..." Height="300" Width="300"> <Grid> <Label> `_Twas brillig, and the slithy toves did gyre and gimble in the wabe: all mimsy were the borogoves, and the mome raths outgrabe.</Label> </Grid> </Window> Am I doing something wrong? Taking other controls is unfortunately not a good option, since I need support of access keys. Replacing the Label with a TextBlock (having TextWrapping="Wrap"), and adjusting its control template to recognize access keys would be perhaps a solution, but isn't it an overkill? Edit: having a non-standard style for label will break skinning, so I would like to avoid it if possible.

  • Silverlight TemplateBinding to RotateTransform

    - by Trog Dog
    I am trying to create the simplest Silverlight templated control, and I can't seem to get TemplateBinding to work on the Angle property of a RotateTransform. Here's the ControlTemplate from generic.xaml: <ControlTemplate TargetType="local:CtlKnob"> <Grid x:Name="grid" RenderTransformOrigin="0.5,0.5"> <Grid.RenderTransform> <TransformGroup> <RotateTransform Angle="{TemplateBinding Angle}"/> <!-- This does not work --> <!-- <RotateTransform Angle="70"/> --> <!-- This works --> </TransformGroup> </Grid.RenderTransform> <Ellipse Stroke="#FFB70404" StrokeThickness="19"/> <Ellipse Stroke="White" StrokeThickness="2" Height="16" VerticalAlignment="Top" HorizontalAlignment="Center" Width="16" Margin="0,2,0,0"/> </Grid> </ControlTemplate> Here's the C#: using System.Windows; using System.Windows.Controls; namespace CtlKnob { public class CtlKnob : Control { public CtlKnob() { this.DefaultStyleKey = typeof(CtlKnob); } public static readonly DependencyProperty AngleProperty = DependencyProperty.Register("Angle", typeof(double), typeof(CtlKnob), null); public double Angle { get { return (double)GetValue(AngleProperty); } set { SetValue(AngleProperty,value); } } } }

  • COMException in System.WIndows.Forms.dll with Interactive Brokers TWS API

    - by Lirik
    Hi, I've been trying to run the sample project provided with the tutorial at stockbotprogramming http://www.stockbotprogramming.com/sharpcibtutorial1.php , but I keep getting a COMException every time I run the application. I have the TWS Client running and the sample VB projects provided with the API are able to connect just fine, but when I try to use the C# sample provided by the tutorial then I get the following exception: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Windows.Forms.dll Th exception happens when I try to add the TWS ActiveX control: namespace CSharpTutorial1 { public partial class Form1 : Form { private AxTWSLib.AxTws tws; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { tws = new AxTWSLib.AxTws(); tws.BeginInit(); tws.Enabled = true; tws.Location = new System.Drawing.Point(32, 664); tws.Name = "tws"; Controls.Add(tws); // <-- EXCEPTION HERE! tws.EndInit(); tws.connect("127.0.0.1", 7496, 0); String msg = "Connected to TWS server version " + tws.serverVersion + "at " + tws.TwsConnectionTime; MessageBox.Show(msg); } } } Does anybody know what could be causing this exception? Any ideas on how to fix it?

  • How to invalidate layout of listbox from custom children

    - by Stephen Price
    I have a custom panel for a listbox <ItemsPanelTemplate x:Key="FloatPanelTemplate"> <Controls:FloatPanel x:Name="CardPanel" /> </ItemsPanelTemplate> The panel lays out its children using its X and Y dependency properties. This all works nicely when the FloatPanel is used by itself - I'm using FrameworkPropertyMetadataOptions.AffectsArrange | FrameworkPropertyMetadataOptions.AffectsMeasure on the dependency properties of the child items to tell the FloatPanel to redraw its layout. When I use it in a Listbox (code above) then it draws fine the first time, but when I drag the children (which modifies the item's X and Y) it is not notifying the Listbox that it needs to redraw the FloatPanel's children. I think the issue is related to the fact that each item in the bound collection is wrapped with a ListBoxItem. Hopefully I've described what i'm doing well enough that someone can tell me how to make the panel (or its children) tell it needs to do the Layout routines again. As I said it works once (initial draw) but then dragging items doesn't work (Listbox isnt aware that its children have changed and needs to relayout.) If I drag an item and then resize the window, the listbox does a layout and the items are drawn in their new locations. How do I notify the ListBox (or more importantly the FloatPanel in the ItemsPanelTemplate) that it needs to do a Layout pass?

  • ASP.Net MVC: Showing the same data using different layouts...

    - by vdh_ant
    Hi guys I'm wanting to create a page that allows the users to select how they would like to view their data - i.e. summary (which supports grouping), grid (which supports grouping), table (which supports grouping), map, time line, xml, json etc. Now each layout would probably have different use a different view model, which inherit from a common base class/view model. The reason being that each layout needs the object structure that it deals with to be different (some need hierarchical others a flatter structure). Each layout would call the same repository method and each layout would support the same functionality, i.e. searching and filtering (hence these controls would be shared between layouts). The main exception to this would be sorting which only grid and table views would need to support. Now my question is given this what do people think is the best approach. Using DisplayFor to handle the rendering of the different types? Also how do I work this with the actions... I would imagine that I would use the one action, and pass in the layout types, but then how does this support the grouping required for the summary, grid and table views. Do i treat each grouping as just a layout type Also how would this work from a URL point of view - what do people think is the template to support this layout functionality Cheers Anthony

  • Get a button in itemscontrol and add eventhandler to its click event

    I have a custom control shows a customer info with an itemscontrol shows this customer's invoices. within the itemscontrol, I have button, in my code behind I want to wire the button's click event to my host window, but do now know how. //public event RoutedEventHandler ViewDetailClick; public static readonly RoutedEvent ButtonViewClickEvent = EventManager.RegisterRoutedEvent( "ButtonViewClick", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(custitem)); public event RoutedEventHandler ButtonViewClick { add { AddHandler(ButtonViewClickEvent, value); } remove {RemoveHandler(ButtonViewClickEvent, value);} } public override void OnApplyTemplate() { base.OnApplyTemplate(); this.lstInv = GetTemplateChild("lstInv") as ItemsControl; lstInv.ItemContainerGenerator.StatusChanged += new EventHandler(ItemContainerGenerator_StatusChanged); } private void ItemContainerGenerator_StatusChanged(object sender, EventArgs e) { if (lstInv.ItemContainerGenerator.Status == System.Windows.Controls.Primitives.GeneratorStatus.ContainersGenerated) { lstInv.ItemContainerGenerator.StatusChanged -= ItemContainerGenerator_StatusChanged; for (int i = 0; i < this.lstInv.Items.Count; i++) { ContentPresenter c = lstInv.ItemContainerGenerator.ContainerFromItem(lstInv.Items[i]) as ContentPresenter; DataTemplate dt = c.ContentTemplate; Grid grd = dt.LoadContent() as Grid; Button btnView = grd.FindName("btnView") as Button; if (btnView != null) { btnView.Click += new RoutedEventHandler(ButtonView_Click); //btnView.Click+= delegate(object senderObj, RoutedEventArgs eArg) //{ // if (this.ViewDetailClick != null) // { // this.ViewDetailClick(this, eArg); // } //}; } } private void ButtonView_Click(object sender, RoutedEventArgs e) { MessageBox.Show("clicked"); //e.RoutedEvent = ButtonViewClickEvent; //e.Source = sender; //RaiseEvent(e); } I succeed getting the btnView, then attach the click event, but the click event never get fired.

  • Can't access resource from Generic.xaml within the Custom Control constructor.

  • Which JavaScript or ASP.NET Charting Component/Tool/Library Will Work For This?

    - by Jason Bunting
    [Update]: Forgot to include ComponentArt... Hi, An interaction designer employed by the client I am currently working for produced some mock-ups, and now it is my job to determine the best way of implementing the charts included therein. After looking at the options I am aware of and was able to find doing some simple Google searches, I have narrowed it down to using either ComponentArt, Dundas Charts or Infragistics, simply because from what I can see of their demos, they have certain features I believe I will need to get things done. Here are the pictures from the mock-ups - ideally I need one piece of software that will cover all of these: This chart seems to be simple enough. Notice the arbitrary spacing between the years - not yet sure if this will be a sticking-point for the client or not. I don't know that I have ever seen a chart like this one - it combines the previous chart with some additional data. Here is the same chart, only this time illustrating what happens when a user mouses-over or clicks on an annotation within the chart. They want the nice styling within the pop-up, so the pop-up needs to be something like an iframe or similar. Any ideas or recommendations would be appreciated, I haven't used charting controls in years, so I am at a bit of a loss and the client wants an estimate soon. Thank you!

  • In a combobox, how do I determine the highlighted item (not selected item)?

    - by Harold Bamford
    First, fair warning: I am a complete newbie with C# and WPF. I have a combobox (editable, searchable) and I would like to be able to intercept the Delete key and remove the currently highlighted item from the list. The behavior I'm looking for is like that of MS Outlook when entering in email addresses. When you give a few characters, a dropdown list of potential matches is displayed. If you move to one of these (with the arrow keys) and hit Delete, that entry is permanently removed. I want to do that with an entry in the combobox. Here is the XAML (simplified): <ComboBox x:Name="Directory" KeyUp="Directory_KeyUp" IsTextSearchEnabled="True" IsEditable="True" Text="{Binding Path=CurrentDirectory, Mode=TwoWay}" ItemsSource="{Binding Source={x:Static self:Properties.Settings.Default}, Path=DirectoryList, Mode=TwoWay}" / The handler is: private void Directory_KeyUp(object sender, KeyEventArgs e) { ComboBox box = sender as ComboBox; if (box.IsDropDownOpen && (e.Key == Key.Delete)) { TrimCombobox("DirectoryList", box.HighlightedItem); // won't compile! } } When using the debugger, I can see box.HighlightedItem has the value I want but when I try and put in that code, it fails to compile with: System.Windows.Controls.ComboBox' does not contain a definition for 'HighlightedItem'... So: how do I access that value? Keep in mind that the item has not been selected. It is merely highlighted as the mouse hovers over it. Thanks for your help.
