Hello everyone,

I have a Panel whose Content is a Scrollable to which I add controls (buttons/labels/etc) at runtime. I now want to write a method with one method parameter that represents the ID of a control. The method must now loop through the controls in the Scrollable, searching for a control whose ID matches the method parameter, and then return the control.

In an old VB .NET app, it was done as follows:
Private Function FindControl(ByVal Name As String) As Control
   
Dim cRef As Control

   
For Each cRef In panMain.Controls
       
If cRef.Name = Name Then
           
Return cRef
       
End If
   
Next
   
Return Nothing
End Function

With a direct conversion to C#:
private Control FindControl(string Name)
{
   
Control cRef;

   
foreach (var cRef in panMain.Controls)
   
{
       
if (cRef.Name == Name)
           
return cRef;
   
}
   
return null;
}

What must I change for it to work correctly with Eto?

Sorry, what I meant was, I have a Scrollable whose Content is a PixelLayout

I was able to get the following to work:

Scrollable scrollMain;  
PixelLayout scrollMainLayout;
scrollMain.Content = scrollMainLayout;  

foreach (Control cRef in scrollMainLayout.Children)
{

} // end foreach


Also, instead of a loop, one can also use FindChild() of the PixelLayout
