ICollection.CountExamples
The following code example demonstrates how to use the Count property to iterate through a control's ControlCollection object. The use of the Control.HasControls property verifies that the control has child controls. If Control.HasControls returns false, the remaining code does not run.
Visual Basic
If HasControls() Then Dim i As Integer For i = 0 To Controls.Count - 1 Controls(i).RenderControl(writer) Next i End If
C#
if (HasControls()) { for (int i=0; i < Controls.Count; i++) { Controls[i].RenderControl(writer); } }
