  • datagridview winform tag only brings back the first row value

    - by jvcoach23
    I'm using visual studio 2008. I have a datagridview in a winform. I've bound to it using an object Private Sub LoadAllCampers() Dim Os As List(Of LE.Camper) = Nothing Dim Oc As New LE.Camper_Controller Os = Oc.GetCamperData(0) With Me.dgResults .DataSource = Os End With CamperBindingSource.DataSource = Os End Sub I have a tag setup on the ID property within the Camper class. when i double click on a row in teh datagridview, i do a me.dgResults.tag and it always shows the first rows ID value. If i change the ordering within the class, it will display a different value, but it's always the first value in the datagridview. I'm missing something simple to get this working.. just don't know what it is. Hopefully someone can spare a minute.

  • Information Label

    - by caisenm
    I am trying to make an information label that should display the events the application doing. deleting data, reading data, writing data, connection to db. etc.. I've added a label to my form and I am changing its text property for each operation like: label1.Text = "stored procedure is being executed.."; But, in the run time the text of the label does not change. I've tried to add the method Application.DoEvents(); to every place I've changed the label's text property. It works fine. But it looks silly. So I've tried to add this method to my label's "TextChanged" event. But it does not work! Am I doing something wrong? Or, is there any efficient way to make an information label?

  • Combo box in a scrollable panel causing problems

    - by Dennis
    I have a panel with AutoScroll set to true. In it, I am programmatically adding ComboBox controls. If I add enough controls to exceed the viewable size of the panel a scroll bar appears (so far so good). However, if I open one of the combo boxes near the bottom of the viewable area the combo list isn't properly displayed and the scrollable area seems to be expanded. This results in all of the controls being "pulled" to the new bottom of the panel with some new blank space at the top. If I continue to tap on the drop down at the bottom of the panel the scrollable area will continue to expand indefinitely. I'm anchoring the controls to the left, right and top so I don't think anchoring is involved. Is there something obvious that could be causing this? Update: It looks like the problem lies with anchoring the controls to the right. If I don't anchor to the right then I don't get the strange behavior. However, without right anchoring the control gets cut off by the scroll bar. Here's a simplified test case I built that shows the issue: public Form1() { InitializeComponent(); Panel panel = new Panel(); panel.Size = new Size(80, 200); panel.AutoScroll = true; for (int i = 0; i < 10; ++i) { ComboBox cb = new ComboBox(); cb.Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top; cb.Items.Add("Option 1"); cb.Items.Add("Option 2"); cb.Items.Add("Option 3"); cb.Items.Add("Option 4"); cb.Location = new Point(0, i * 24); panel.Controls.Add(cb); } Controls.Add(panel); } If you scroll the bottom of the panel and tap on the combo boxes near the bottom you'll notice the strange behavior.

  • Grouping Windows Forms Radiobuttons with different parent controls in C#

    - by Jerry
    Hi, I've got a Windows Forms application in which I have a number of RadioButtons. These RadioButtons are placed within a FlowLayoutPanel which automatically arranges them for me. All RadioButtons that are directly added to the FlowLayoutPanel are grouped, meaning I can select only one of them. However, some of these RadioButtons are paired up with a TextBox so I can supply some argument there. But to have all this arranged properly, I add a Panel control to the FlowLayoutPanel so I can control the alignment of the RadioButton and TextBox relatively to each other myself. These RadioButtons now have their own respective Panels as parent controls and thus are no longer included in the radio group with the other RadioButtons. I read that the the RadioButtons that are in the System.Web.UI namespace have a GroupName property, but unfortunately their System.Windows.Forms counterparts lack this property. Is there some other way I can group these radio buttons are am I going to have to handle onClick events myself? Thanks, Jerry

  • How to develop asp.net web service to create the web method which can take the parameter of type win

    - by Shailesh Jaiswal
    I am developing asp.net web service. I am developing this web service so that OPC ( OLE for process control) client application can use it. In this web service I am using the built-in functions provided by the namespaces using OPC, using OPCDA, using OPCDA.NET. I have also added the namespace using System.Windows.Forms in this web service so that I can use the windows form control. In that we service I have created on web method which takes the parameter of type windows form control as given below. public void getOPCServerItems(TreeView tvServerItems, ListView lvBranchItems) { ArrayList ArrlstObj = new ArrayList(); ItemShowTreeList = OpcSrv.ShowBrowseTreeList(tvServerItems, lvBranchItems); ItemShowTreeList.BrowseModeOneLevel = true; // browse hierachy levels when selected. (default) ItemShowTreeList.Show(OpcSrv.ServerName); } In the above web method I need to pass the values to the built-in function ShowBrowseTreeList() (found in OPC, OPCDA, OPCDA.NET namespaces). This function takes the two parameter of windows form control type. These parameters are Treeview & ListView control of the windows form. In the above web method ShowBrowseTreeList() method automatically create the treeview & listview structure of the available items. Now as I am consuming the web service so I need to pass the values to the webmethod getOPCServerItems(). But as I my consuming application is asp.net application there is no such windows form control. In asp.net application there are also & control. I want to display The data returned in these asp.net controls rather than windows form control. I am not getting the way what should I need to do or how should I pass the values form my client application to this web service ? In the above method getOPCServerItems() when I use the parameter of type treeview & listview it generate s error "Cannot serialize member System.ComponentModel.Component.Site of type System.ComponentModel.ISite because it is an interface.". Can you provide me the the way In which I can write the above web method & how should I pass parameter to the Treeview & Listview control (windows form control) from my asp.net application ? which controls I should use to pass parameters ? Is there any need to do any type of casting ? Can you provide me the the code for above web method so that I can resolve the above issue ?

  • A good way in Visual Studio to have user entered time frame?

    - by Ben
    Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using visual studio controls? At the moment i have two numeric up downs, one for time and one for minutes that i then parse to create a timespan. The only other idea i have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  • IS there a simple way to remove Alt-Character shortcuts at runtime

    - by Dan Neely
    I have a dialog with a number of Alt-Letter shortcuts on labels for textboxes/etc. This dialog can present data in either an editable or a read-only mode. I've received a request to hide the underlines for the shortcuts if the dialog is in read only mode. Other than editing the label text at runtime (ugh) is there any way to remove them? If you don't know what I'm referring to by alt-Letter shortcuts see this question.

  • Propertygrid changes not picked up when using menu shortcut for saving

    - by Ebbe
    I am trying to implement a simple windows forms application, where the user can edit instances of a simple Person class. The application makes use of the standard propertygrid, assigning instances of the Person class to the SelectedObject property of the propertygrid. When the user clicks the menu item Save, the application gets the selected item from the propertygrid and saves it. This works fine. However, if a shortcut such as ctrl+S, assigned to the menu item, is used for saving the SelectedObject of the propertygrid, then the changes are not picked up. It appears to be related to the fact that the properties of the Person object are not updated unless the field in the propertygrid looses focus, and the ctrl+S shortcut doesn’t take away focus from fields in the propertygrid. Other developers, such as Mark Gilbert, have solved this issue by forcing away focus from the propertygrid, but this seems to be a bit of a hack, especially since it would be nice to keep the focus at the field. The Visual Studio developers apparently got it right, but I haven’t figured out how.

  • Drawing a relative line in C#

    - by icemanind
    Guys, I know this is going to turn out to be a simple answer, but I can't seem to figure it out. I have a C# Winform application that I am trying to build. I am trying to draw a white line 60 pixels above the bottom of the form. I am using this code: private void MainForm_Paint(object sender, PaintEventArgs e) { e.Graphics.DrawLine(Pens.White, 10, this.Height-60, 505, this.Height-60); } Simple enough, however no line is drawn. After some debugging, I figured out that it IS drawing the line, but it is drawing it outside my form. If I change the -60 to -175, then I can see it at the bottom of my form. This would solve my problem, except as my form's height changes, the line draws closer and closer to the bottom of my form until eventually, its off the form again. What am I doing wrong? Am I using the wrong graphics unit? Or is there a more complex calculation I need to do to determine 60 pixels from the bottom of my form?

  • Getting "" at the beginning of my XML File after save()

    - by Remy
    I'm opening an existing XML file with c# and I replace some nodes in there. All works fine. Just after I save it, I get the following characters at the beginning of the file:  (EF BB BF in HEX) The whole first line: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> The rest of the file looks like a normal XML file. The simplified code is here: XmlDocument doc = new XmlDocument(); doc.Load(xmlSourceFile); XmlNode translation = doc.SelectSingleNode("//trans-unit[@id='127']"); translation.InnerText = "testing"; doc.Save(xmlTranslatedFile); I'm using a C# WinForm Application. With .NET 4.0. Any ideas? Why would it do that? Can we disable that somehow? It's for Adobe InCopy and it does not open it like this. UPDATE: Alternative Solution: Saving it with the XmlTextWriter works too: XmlTextWriter writer = new XmlTextWriter(inCopyFilename, null); doc.Save(writer);

  • Implementing Read Only view in Winform App

    - by Refracted Paladin
    I have an in house winform app for viewing, editing, and inserting member data. There are about 40 sepertate form pages that they use to manipulate different portions of the data. My question is this; What is the best way of implementing a read only view for a form page? My thoughts were to cycle through the controls setting Enabled = False or leave them be but not allow any data changes(no Save Button etc) unless it is "unlocked". I am curious how others handle this with WinForm apps?

  • Why does TabStop stop working??

    - by Jerry
    I have a project that uses a series of auto-generated user control instances. The user-control itself exists, but I populate a panel with a series of these user controls, one for each item in my collection. Each user control displays a ton of information, but only ONE text field is editable. All of the other fields have TabStop set to false, and are marked as ReadOnly. The tab order of each user control is set at the time it is created so that the tab-key goes from one field to the next (or ... it's supposed to). When I have TWO fields on my user control whose TabStop is set to true, everything works great. But if I only have ONE field whose TabStop is true, the tab key stops working, and I have to physically CLICK on the next user control for it to gain focus. What's up? Has anyone else seen this behavior? Am I doing something stupid as usual?

    Hi, My application has several controls. Like in one screen has TreeView on left side, GridView with paging in the middle and 4 buttons at right side. The controls properly appear when the form is in a maximized state, but if I minimize it the controls do not properly fit on the screen. I tried with different different tricks like table layout.. in dat I added a panel, etc... But I could not solve the problem. How can I create such type of screens which fits independently of size of my window? Thanks

  • Working examples of winform/WPF apps

    - by melody
    I'm a user interface designer. The project I'm working on is a dashboard that will have several interactive and customizable widgets (think Netvibes, etc.). The development group is going to be using either WinForm or WPF to build the dashboard and widgets. I need to understand the capabilities of each technology better and see a sampling of actual working apps to help accomplish this. I can't download and build examples... need live examples somewhere on the web. Can you point me to live, existing apps? Thx.
