  • Setting the background color of WPF TabControl inactive tabs

    - by David Veeneman
    Is there a simple way to set the background brush of all inactive tabs in a WPF TabControl? I want to emulate the look of VS 2010 on a TabControl--the background color of the control's inactive tabs should match the background color of the window in which the TabControl is sited, so that you see only the text of the tab, and not the tab itself. I know it will take a ControlTemplate to do it; I am trying to figure out what to put in the control template. Put another way, How do I specify that a particular brush should be applied to all inactive tabs? Thanks for your help.

  • Dynamically add event to custom control (Confirm Message Box)

    - by Nyein Nyein Chan Chan
    I have created a custom cofirm message box control and I created an event like this- [Category("Action")] [Description("Raised when the user clicks the button(ok)")] public event EventHandler Submit; protected virtual void OnSubmit(EventArgs e) { if (Submit != null) Submit(this, e); } The Event OnSubmit occurs when user click the OK button on the Confrim Box. void IPostBackEventHandler.RaisePostBackEvent(string eventArgument) { OnSubmit(e); } Now I am adding this OnSubmit Event Dynamically like this- In aspx- <my:ConfirmMessageBox ID="cfmTest" runat="server" ></my:ConfirmMessageBox> <asp:Button ID="btnCallMsg" runat="server" onclick="btnCallMsg_Click" /> <asp:TextBox ID="txtResult" runat="server" ></asp:TextBox> In cs- protected void btnCallMsg_Click(object sender, EventArgs e) { cfmTest.Submit += cfmTest_Submit;//Dynamically Add Event cfmTest.ShowConfirm("Are you sure to Save Data?"); //Show Confirm Message using Custom Control Message Box } protected void cfmTest_Submit(object sender, EventArgs e) { txtResult.Text = "User Confirmed";//I set the text to "User Confrimed" but it's not displayed txtResult.Focus();//I focus the textbox but I got Error } The Error I got is- System.InvalidOperationException was unhandled by user code Message="SetFocus can only be called before and during PreRender." Source="System.Web" So, when I dynamically add and fire custom control's event, there is an error in Web Control. If I add event in aspx file like this, <my:ConfirmMessageBox ID="cfmTest" runat="server" OnSubmit="cfmTest_Submit"></my:ConfirmMessageBox> There is no error and work fine. Can anybody help me to add event dynamically to custom control? Thanks.

  • My MS Access control displays no text for appended items following an append query

    - by Zaid
    The control in question is part of a datasheet-style subform that feeds off a multi-field combo-box. The control is bound to the first field of the combo box, an ID field which is hidden from view (column width set to zero). Consequently, the second field (Code) is displayed in the control when an item is selected from the combo box. I'm using a form button action to append values to this datasheet. It seems that because I need to INSERT ID values in, the control is unable to display the corresponding Code value. Nothing is visible, unless I go manually into the combo box and select an item from it. How can I get the control to display the Code value?

  • DoubleAnimation in ScaleTransform

    - by Adam S
    I'm trying, as an exhibition, to use a DoubleAnimation on the ScaleX and ScaleY properties of a ScaleTransform. I have a rectangle (144x144) which I want to make rectangular over five seconds. My XAML: <Window x:Class="ScaleTransformTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <Grid> <Rectangle Name="rect1" Width="144" Height="144" Fill="Aqua"> <Rectangle.RenderTransform> <ScaleTransform ScaleX="1" ScaleY="1" /> </Rectangle.RenderTransform> </Rectangle> </Grid> </Window> My C#: private void Window_Loaded(object sender, RoutedEventArgs e) { ScaleTransform scaly = new ScaleTransform(1, 1); rect1.RenderTransform = scaly; Duration mytime = new Duration(TimeSpan.FromSeconds(5)); Storyboard sb = new Storyboard(); DoubleAnimation danim1 = new DoubleAnimation(1, 1.5, mytime); DoubleAnimation danim2 = new DoubleAnimation(1, 0.5, mytime); sb.Children.Add(danim1); sb.Children.Add(danim2); Storyboard.SetTarget(danim1, scaly); Storyboard.SetTargetProperty(danim1, new PropertyPath(ScaleTransform.ScaleXProperty)); Storyboard.SetTarget(danim2, scaly); Storyboard.SetTargetProperty(danim2, new PropertyPath(ScaleTransform.ScaleYProperty)); sb.Begin(); } Unfortunately, when I run this program, it does nothing. The rectangle stays at 144x144. If I do away with the animation, and just ScaleTransform scaly = new ScaleTransform(1.5, 0.5); rect1.RenderTransform = scaly; it will elongate it instantly, no problem. There is a problem elsewhere. Any suggestions? I have read the discussion at http://www.eggheadcafe.com/software/aspnet/29220878/how-to-animate-tofrom-an.aspx in which someone seems to have gotten a pure-XAML version working, but the code is not shown there. EDIT: At http://stackoverflow.com/questions/2131797/applying-animated-scaletransform-in-code-problem it seems someone had a very similar problem, I am fine with using his method that worked, but what the heck is that string thePath = "(0).(1)[0].(2)"; all about? What are those numbers representing?

  • How do I bind one TabControl to the TabItems of another TabControl in WPF?

    - by joebeazelman
    I've defined the following TabControl called TabControl1: <TabControl> <TabItem Header="Cheese"> The Cheese Tab </TabItem> <TabItem Header="Pepperoni"> The Pepperoni Tab </TabItem> <TabItem Header="Mushrooms"> The Mushrooms Tab </TabItem> </TabControl> I've defined another TabControl, TabControl2 which is dynamically loaded from an add-in or plugin: <TabControl> <TabItem Header="Anchovies"> The AnchoviesTab </TabItem> <TabItem Header="Jalepenos"> The Jalepenos Tab </TabItem> <TabItem Header="Rattle Snake"> The Rattle Snake Tab </TabItem> </TabControl> After TabControl1 binds to TabControl2 after the "Cheese" item, TabControl1 should look like this: <TabControl> <TabItem Header="Cheese"> The Cheese Tab </TabItem> <TabItem Header="Anchovies"> The AnchoviesTab </TabItem> <TabItem Header="Jalepenos"> The Jalepenos Tab </TabItem> <TabItem Header="Rattle Snake"> The Rattle Snake Tab </TabItem> <TabItem Header="Pepperoni"> The Pepperoni Tab </TabItem> <TabItem Header="Mushrooms"> The Mushrooms Tab </TabItem> </TabControl>

  • Setting style of ContextMenu on subitems

    - by thedesertfox
    I have created a custom style and template for MenuItem and ContextMenu, and for my first level, that works great, but whenever I add a SubMenu item, the style of that ContextMenu reverts back to the default style. How can I make sure that item uses my custom style? I've tried using the <;Style TargetType="ContextMenu" Key="{x:Type ContextMenu}" syntax as well, and it doesn't seem to be overriding it either.

  • ASP.Net Charting Control - Display a Threshold

    - by Damien
    Is it possible to display a static line across a chart which appears at a given point on the Y Axis? So say I have a chart which measures test scores, ranges which 0 to 100 which 70% being the pass mark and therefore displaying a straight line across the chart at this point? Would I have to add a new series or is there a property for such a function? Thanks, Damien

  • Binding a slider value on the height of its thumb in WPF

    - by sofri
    Hi, I have a databinding problem in WPF. I would like to "customise" a slider in a way that the thumb grows when you move the slider to the right and the thumb shrinks when you move the slider to the left. So I edited the template for the slider and changed the look of the slider so the slider looks like I want it to. But now I have to bind the height of the thumb to the value of the slider but I do not know how that works. I did some simple data binding things but I cannot figure out how I can bind this "thumb height" that's inside of my slider's template to the slider's value that's inside the User Control where my slider is in. So how can I do it?

  • WPF Textbox "normal" text input

    - by Ash Rowe
    G'day, I'm not sure if this is a problem relevant to only me or if anyone else has this issue also. None the less, I'll try and describe what is going on here. I have a few textbox's, default style, etc. I set an explicit maxwidth and maxheight to prevent resize when the text exceeds the default width of the textbox. The issue is that the text wraps to the next line, but I only want single line. So I set maxlines to 1 and textwrapping to NoWrap. That's fine. Now the carat and typed text disappears under the edges of the textbox when the width is exceeded and the only way I can get the carat and newly typed text back into view is by pressing the left and right arrows. Coming from MFC and using textboxes all the time with HTML, I would have thought the default behaviour would be to have the textbox content scroll with the carat or am I missing something here? Thank you, Ash

  • How to bind a WPF CustomControl to a ListBox

    - by VivyG
    I've just started to learn WPF this week so please accept my apologies if I am being stupid or missing fundamental points! Iam trying to build a very simple Contact browser. I have a Collection of Contact objects that displayed in a ListBox control which shows the FullName of the Contact and to the right I have a customControl called BasicContactCard. This is the XAML for the ContacWindow that displays the ListBox: <DockPanel Width="auto" Height="auto" Margin="8 8 8 8"> <Border Height="56" HorizontalAlignment="Stretch" VerticalAlignment="Top" BorderThickness="1" CornerRadius="8" DockPanel.Dock="Top" Background="Beige"> <TextBox Height="32" Margin="23,5,135,5" Text="Search for contact here" FontStyle="Italic" Foreground="#FFAD9595" FontSize="14" BorderBrush="LightGray"/> </Border> <ListBox x:Name="contactList" DockPanel.Dock="Left" Width="192" Height="auto" Margin="5 4 0 8" /> <Grid> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="0.125*" /> </Grid.RowDefinitions> <local:BasicContactCard Margin="8 8 8 8" /> <Button Grid.Row="1" x:Name="exit" Content="Exit" HorizontalAlignment="Right" Width="50" Height="25" Click="exit_Click" /> </Grid> </DockPanel> and this is the XAML for the CustomControl: <DockPanel Width="auto " Height="auto" Margin="8,8,8,8"> <Grid Width="auto" Height="auto" DockPanel.Dock="Top"> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> </Grid.RowDefinitions> <TextBlock x:Name="companyField" Grid.Row="0" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Company"/> <TextBlock x:Name="contactField" Grid.Row="1" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Contact"/> <TextBlock x:Name="phoneField" Grid.Row="2" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Phone"/> <TextBlock x:Name="emailField" Grid.Row="3" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="email"/> </Grid> </DockPanel> The problem I have is how do I bind the individual elements of the CustomControl to the object behind the SelectedItem in the ListBox?
