Hi sarag,

The recommended approach would be to expose boolean properties for each column in your business object and to bing the ToggleButtons' IsChecked properties to those boolean properties. In this way you will be able to retrieve the checked/ unchecked values of each button. Furthermore, you will ensure that even when scrolling, the state of those buttons will still be kept.

Hello sarag,

Is it not appropriate for you to handle the Checked event of the RadToggleButton ?

yes i can do that but the problem is columns are generating dynamically at runtime, the below code will work for cell[0], but i need to do for the remaining 10 coloumns. i need to find some way to find what button is click. i need the index of the header coloum where header is toggle button please see the code

Hello sarag,

You may handle the Checked event as follows:

private void ToggleButton_Checked(object sender, RoutedEventArgs e)
        {
            var button = sender as ToggleButton;
            var headerCell = button.ParentOfType<GridViewHeaderCell>();
            var displayIndex = headerCell.Column.DisplayIndex;

        }

The displayIndex will give you the information for which column's header has been clicked.
