Container control?

Container control?

• Justin Learning

  ok, :) buy I was talking about design time...

  Just one more thing... this attribute is required for design-time support. Adding controls to other controls at runtime also works without it:

  UserControl11.Controls.Add(Button1)
  ' Set button's position etc...

  Hi,

  to make your control act like a container for other controls at design time, you have to add a special System.ComponentModel.Designer attribute to your control declaration, something like:

  <System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner,System.Design", GetType(System.ComponentModel.Design.IDesigner))> _
  Public Class UserControl1
      Inherits System.Windows.Forms.UserControl
  
  End Class

  You can also put this attribute in your control's designer file (UserControl1.Designer.vb)...

  Sorry guys,

  

  Doesn't work for me - none of the both methods, Maybe I'm missing something

  Sine RDGS is open source, you can check out the SVN and see yourself. The sources are at: https://svn.sourceforge.net/svnroot/rdgs/windows_x86/.

  A good program for this is TortoiseSVN. Just point it to the above url.

  Thanks. Any help is appreciated.

  Hi.
  
  Thank you. I'll try that today when I get home. The first method didn't work for me - I rebuilt the project so I'll try with the second one.

  Ok, doesn't work....

  

  Code.....

  <System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner,System.Design", GetType(System.ComponentModel.Design.IDesigner))> _

  Public Class ExpandContainerNet

  Inherits System.Windows.Forms.UserControl

  When I drop a control over it at design time it just gets behind it! Thanks for help.

  Oh my god! I'm feeling like a nOOb. All of your answers worked. The problem I had was that I put a panel into the control, so the other controls couldn't show up.

  Thanks to all who helped.

  I probably don't know what I'm talking about here, but don't you have to set the parent similar to:

  NumericUpDown1.Parent = TextBox1

  Just throwing out ideas.

  The following is another idea that may work for you.

  You could inherit from the panel control instead of the usercontrol. Maybe you should just try if this works for you.

  Public Class UserControl1
  Inherits System.Windows.Forms.Panel
  
  'Some more coding here
  
  End Class

  Hi again,

  so here's the steps to add the Designer attribute... use one of the following  procedures:

  Procedure A

  1. Add new user control to the project and open its code in the editor. You'll see something like

  Public Class UserControl1

  End Class

  2. Delete and replace the above code with the following:

  <System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner,System.Design", GetType(System.ComponentModel.Design.IDesigner))> _
  Public Class UserControl1
      Inherits System.Windows.Forms.UserControl
  
  End Class

  3. Rebuild the project and add the control on a form.

  Procedure B

  1. Add new user control to the project. In Solution Explorer, choose Show All Files. Open control's Designer file (UserControl1.Designer.vb). You'll see something like

  <Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
  Partial Class UserControl1
      Inherits System.Windows.Forms.UserControl

  on the top... 2. Add the Designer attribute to this so it will look like:

  <Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
  <System.ComponentModel.Designer("System.Windows.Forms.Design.ParentControlDesigner,System.Design", GetType(System.ComponentModel.Design.IDesigner))> _
  Partial Class UserControl1
      Inherits System.Windows.Forms.UserControl

  3. Rebuild the project and add the control on a form.

  Hope this helps. Let me know how it goes...

  Andrej

  P.S.: it's important to (re)build the project/control for this to work...
