[Solved] Monitor column visible state changed in ColumnChooser

[Pavel]

Hi,

I have a problem with ColumnChooser in RadGridView.

Please tell me how can I monitor when column visible state changed (For example when I drag and drop column from ColumnChooser to RadGridView or double click on it) ? 

There may be some event ? 

Any help would be appreciated!

Regards!

Hello Pavel,

This should work for you.
Create an event handler for each of the column to monitor the RadPropertyChanged event

For Each c As GridViewDataColumn In Me.RadGridView1.Columns
    AddHandler c.RadPropertyChanged, AddressOf Column_RadPropertyChanged
Next

...and then you can find out information about the column

Private Sub Column_RadPropertyChanged(ByVal sender As Object, ByVal e As RadPropertyChangedEventArgs)
    If String.Equals(e.Property.Name, "IsVisible") Then
        Dim column As GridViewDataColumn = CType(sender, GridViewDataColumn)
        MessageBox.Show(column.Name & " visibility changed to: " & column.IsVisible.ToString())
    End If
End Sub

Hope that helps
Richard
