Remarks
This is useful in situations where the normal validating events are fired after certain
other events (i.e. tree view and data grid item selection events).
Example
C#
// Prevent a change of the tree view node if the current row
// template in the data list is not valid.
private void tree_BeforeSelect(object sender, TreeViewCancelEventArgs e)
{
e.Cancel = !dataList.IsValid;
}VB
' Prevent a change of the tree view node if the current row
' template in the data list is not valid.
Private Sub tree_BeforeSelect(sender As Object, e As TreeViewCancelEventArgs) _
Handles tree.BeforeSelect
e.Cancel = Not dataList.IsValid
