issues with user control inside a DataRepeater

Question

Hi,

In WinForm, I have a user control which contains a textbox and a button (with an image on the button). In the user control, I have a property to change the width of the textbox. I put the user control on a DataRepeater. In Design time, it is good, I see the textbox, the button and his image. I can change the width property.

But at run time, it is the horror. The user control lost the image of the button and width (it has the original width) and I can’t intercept the event on the button. Everything is good with the same user control when I put it on a form or a panel.

In the same DataRepeater I put also TextBox. The DataRepeater bound with a Business List Base (Businee objects from CSLA). The binding is ok for the textbox inside the DataRepeater but not for the user control.

Thanks if you have a solution.

Hi Dominique,

I didn't reproduce this scenario. Would you like to upload your project here?

I look forward you.

Thanks, Mike, for your answer

I added my user control on a small sample project and I can upload it.

But how can I upload a file (.zip) ?

Answer 3

Hi dg78,

Upload your project on skydrive, and post the download link here.

Thank you.

Hi Mike,

I can’t upload the project (too big) but I do a small project to see the problem.

I used the sample in this article :

http://blogs.msdn.com/b/vsdata/archive/2009/08/12/datarepeater-control-for-windows-forms.aspx and I added my user control : ucTBL (textbox / Button / Label).

I put a ucTBL in the DataRepeater.

In the IDE it is OK but at runtime each property is lost : width, image, binding and I can’t intercept the mouse click  on the button.

I put also a ucTBL outside the DataRepeater and it is OK .. but only for the selected item (it is normal).

Here the binding is good, it is the good image and width.

I put a breakpoint on Button1_Click in  the ucTBL. It is OK with the ucTBL outside the DataRepeater and Not OK with ucTBL inside the DataRepeater.

I upload this sample at SkyDrive :

Thanks for help.

Hi Dg78,

I have test your code, after I add this code, it works on my side:

    Private Sub DataRepeater1_ItemCloned(sender As Object, e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) Handles DataRepeater1.ItemCloned
        Dim butS As Button = Me.UcTBL72.Controls("dgButton1")
        Dim f1S As FieldInfo = GetType(Control).GetField("EventClick", BindingFlags.[Static] Or BindingFlags.NonPublic)
        Dim objS As Object = f1S.GetValue(butS)
        Dim piS As PropertyInfo = butS.[GetType]().GetProperty("Events", BindingFlags.NonPublic Or BindingFlags.Instance)
        Dim listS As EventHandlerList = DirectCast(piS.GetValue(butS, Nothing), EventHandlerList)
        'list.[RemoveHandler](obj, list(obj))


        Dim butT As Button = e.DataRepeaterItem.Controls.Find("dgButton1", True)(0)
        Dim f1T As FieldInfo = GetType(Control).GetField("EventClick", BindingFlags.[Static] Or BindingFlags.NonPublic)
        Dim objT As Object = f1T.GetValue(butT)
        Dim piT As PropertyInfo = butT.[GetType]().GetProperty("Events", BindingFlags.NonPublic Or BindingFlags.Instance)
        Dim listT As EventHandlerList = DirectCast(piT.GetValue(butT, Nothing), EventHandlerList)
        listT.[AddHandler](objT, listS(objS))
    End Sub

You know, the datarepeater control always clone a repeater Item from the template, and the template is designed in the design time. When clone the template, the event handlers are not copied. So we need to add them again.

Best regards,

Thanks, Mike, you solve my problem about event.

I think that Microsoft should have included the code you wrote inside the DataRepeater. If I put several ucTBL inside the datarepeater I need to duplicate you code for each ucTBL. What’s a pain !!

How do you solve the problems about properties (longeur, image) and about the binding of ucTBL7 ?

Are there good documentation and samples about these points ?

Best regards

Answer 7

Hi Dg78,

I am afraid so. And so far, I haven't found such documentation. 

Please report this on Microsoft connect site: http://connect.microsoft.com/VisualStudio/ if you want to let Microsoft know.

Hi Dg78,

Would you mind to close this thread?

About your question "How do you solve the problems about properties (longeur, image) and about the binding of ucTBL7 ?" 

I suggest you to ask it in a new thread since this thread is a little old  with more details information.

Best regards,

Answer 9

Hi Mike,

I don’t wish to close this thread because, as you say, I don’t have an answer about the question :

"How do you solve the problems about properties (longeur, image) and about the binding of ucTBL7 ?" 

I think that it is not a good idea to close this thread and open a new with the same question and the same details. All details information are in this thread with a link for a sample.

Everybody that try this sample can see the problem between the form in IDE and the form during runtime : the properties are lost and the binding on ucTBL7 doesn’t work.

Outside the DataRepeater, I put a ucTBL7 (it is the same that it is in the datarepeater : longeur = 60, the image in the button is a mail and there is the databinding ). It is good in this ucTBL7 but it is not good in the ucTBL7 inside the datarepeater : longueur = 120 (it is the default property), image = a book (always default property, TypeBtn = 0) and the databinding does not work).

The ucTBL7 outside the datarepeater give the Postal Code and City but only for the select item in the datarepeater. I want the same but inside each item of the datarepeater.

Best regards

Dominique

Answer 10

Hi Dg78,

But what property is longeur and image? There is no such properties in your usercontrol.

Would you like to point me what I am missing?

Thank you.

Answer 11

Thanks Mike for answer,

The user control ucTBL7 contains a textbox, a button and a label (not exactly a label but a textbox in readonly).

Longueur is a property in the user control ucTBL7. It means the width of the first textbox (for input).

(Sorry, I wrote Longeur in the posts but it is Longueur).

Image is the image of the button. In Properties /  Resources of the project, there are two images : book and email.

Look the form Form1 in the IDE, you can see a ucTBL7 inside the datarepeater and another ucTBL7 outside the datarepeater. The ucTBL7 outside is a copy of the ucTBL7 inside.

Longueur and image are managed in the user control ucTBL code :

  <Category("z2 en plus pour dgTextBox1"), Description("longueur du dgTextBox1")> _
  Public Property Longueur() As Integer
    Get
      Return Me.dgTextBox1.Width
    End Get
    Set(ByVal value As Integer)
      If Me.dgTextBox1.Width <> value Then
        'If OutputDebug Then
        Console.WriteLine(Me.dgTextBox1.Width.ToString + " / " + value.ToString)
        'End If
        Me.dgTextBox1.Width = value
        Me.dgButton1.Location = New Point(Me.dgTextBox1.Location.X + value + 3, Me.dgButton1.Location.Y)
        Me.dgTextBox2.Location = New Point(Me.dgButton1.Location.X + 29, Me.dgTextBox2.Location.Y)
        If mAvecLabel = False Then
          Me.Width = Me.dgTextBox1.Location.X + value + 29 ' 2 + 26 + 1
          Me.dgTextBox2.Width = 0
        Else
          If Me.Width < Me.dgTextBox2.Location.X Then
            Me.Width = Me.dgTextBox2.Location.X + 101
          End If
          Me.dgTextBox2.Width = Me.Width - Me.dgTextBox2.Location.X - 1
        End If
      End If
    End Set
  End Property ' modif zones
 
  <Category("z3 en plus pour dgButton"), _
  DefaultValue(9), _
  Description("buttun type : 0=book  1=mail")> _
  Public Property TypeBtn() As Integer
    Get
      Return mTypeBtn
    End Get
    Set(ByVal value As Integer)
      mTypeBtn = value
      If value = 0 Then
        Me.dgButton1.Image = My.Resources.book
      End If
      If value = 1 Then
        Me.dgButton1.Image = My.Resources.email
      End If
    End Set
  End Property

In the user control, I put (with IDE), the width of the Textbox at 120 and the BackgroundImage of the button with the book image of Resources.

For the two objects ucTBL7 inside and outside, I put (with IDE) Longueur = 60 and TypeBtn = 1 (image = email).

I put also the databinding :

- Texte1 : EmployeesBindingSource - Postal Code

- Texte2: EmployeesBindingSource - City

Then these two objects have the same Longueur (= width of the textbox) and the same image in the button (= email).

In the IDE, the two objects are correct with Longueur = 60 and image = email.

Run the code and now the ucTBL7 outside the datarepeater is always correct (same Longeur as in IDE and email image) and the binding is correct.

Look the ucTBL7 inside the datarepeater and you see that Longeur take the default property in the user control ucTBL7 (= 120) instead the value = 60  (the width of the textbox of the ucTBL7 is twice the width of the textbox of the ucTBL7 outside) and the image change to become book image (default backgoundimage of the button). You can see also that the databinding does not work.

Best Regards

Dominique

Dear MSFT,

Is it a joke ?

Near one month after my question, because Mike leaves the question and nobody can answer, you decree that it is a paid question. It is too easy.

I think that my question is almost about a bug. Now customers must pay for bugs ??

I would point you that I am a partner with a contract that said : you can use managed forum and Microsoft answers in the two days.

Perhaps it is not a managed forum, so give me the link for the good forum or reconsider your position.
