Examples

The following example demonstrates how to display a selection mode label when the ItemHeaderVisible property changes. It assumes that you have a form that contains a DataRepeater control named DataRepeater1 and a Label named SelectionModeLabel.

Private Sub DataRepeater1_ItemHeaderVisibleChanged(
    ) Handles DataRepeater1.ItemHeaderVisibleChanged

    ' Display the selection mode in the label.
    If DataRepeater1.ItemHeaderVisible = False Then
        SelectionModeLabel.Text = "Selected item marked by selection " & 
         "rectangle."
    Else
        SelectionModeLabel.Text = "Selected item marked by item " & 
         "header."
    End If
End Sub
private void DataRepeater1_ItemHeaderVisibleChanged(object sender, System.EventArgs e)
{
    // Display the selection mode in the label.
    if (dataRepeater1.ItemHeaderVisible == false)
    {
        selectionModeLabel.Text = "Selected item marked by selection " +
         "rectangle.";
    }
    else
    {
        selectionModeLabel.Text = "Selected item marked by item " +
         "header.";
    }
}
