Hi,

We have a situation where we have the RadGridView with ComboBoxes in two of its columns. There are two Text columns as well.

If the mouse is kept over a combo box column and the mouse scroll is used, the Grid scroll bar does not fire but the combo box changes selection. However if the mouse is kept above a Text column cell and the mouse scroll is used, the grid scroll bar works as usual. We don't want this disparity. We want the grid scroll bar to work even if the mouse is kept over the radcombobox column cell.

Another challenge is the version of Telerik.Windows.Controls.GridView.dll that we have in our project is 2011.1.0419.35.

I have tried to play with by hooking the OnPreviewMouseWheel event of the RadComboBox that resides in the grid cell. But seems it still makes the combo box scroll.

 

var comboBox = sender as RadComboBox;
            if (comboBox != null)
            {
                if (grid != null)
                {
                    //Copy over event arg members and raise it
                    var newarg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta)
                    {
                        RoutedEvent = RadGridView.PreviewMouseWheelEvent,
                        Source = sender
                    };
                    e.Handled = true;
                    grid.RaiseEvent(newarg);
                }
            }

Any help will be appreciated.


regards,
J
