Examples

The following code example shows how to use the DesignerRegionMouseEventArgs to identify the region that was clicked and to change view accordingly. This example is part of a larger example provided for the EditableDesignerRegion class.

// Handler for the Click event, which provides the region in the arguments.
protected override void OnClick(DesignerRegionMouseEventArgs e)
{
    if (e.Region == null)
        return;

    // If the clicked region is not a header, return
    if (e.Region.Name.IndexOf("Header") != 0)
        return;

    // Switch the current view if required
    if (e.Region.Name.Substring(6, 1) != myControl.CurrentView.ToString())
    {
        myControl.CurrentView = int.Parse(e.Region.Name.Substring(6, 1));
        base.UpdateDesignTimeHtml();
    }
}

' Handler for the Click event, which provides the region in the arguments.
Protected Overrides Sub OnClick(ByVal e As DesignerRegionMouseEventArgs)
    If IsNothing(e.Region) Then
        Return
    End If

    ' If the clicked region is not a header, return
    If e.Region.Name.IndexOf("Header") <> 0 Then
        Return
    End If

    ' Switch the current view if required
    If e.Region.Name.Substring(6, 1) <> myControl.CurrentView.ToString() Then
        myControl.CurrentView = Integer.Parse(e.Region.Name.Substring(6, 1))
        MyBase.UpdateDesignTimeHtml()
    End If
End Sub

Remarks

The Region property represents the control designer region that was clicked, if any.

The Region property is initialized by the DesignerRegionMouseEventArgs constructor.
