Examples

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.

if (HasControls()) {
                 for (int i=0; i < Controls.Count; i++) {
                     Controls[i].RenderControl(writer);
                 }
   }

If HasControls() Then
    Dim i As Integer
    For i = 0 To Controls.Count - 1
        Controls(i).RenderControl(writer)
    Next i
End If
