How to disable switching to auto GridView column width by double-clicking on GridViewHeaderCell.RightHeaderGripper

[Eduard]

Hi,

I`m looking for a way to disable the behavior when double-click on the separator between header cells of GridView sets column to adjust its width according to the widths of all currently visible items inside. For example WinForms DataGridView element has ColumnDividerDoubleClick event which allows me to override this behavior. I`m supposing that there should be something similar for GridView

Can you offer any advice?

Hello Eduard,

The RadGridView control does not expose an API that would allow you to prevent this behavior from occurring out-of-the-box. However, this could still be achieved by adding a new handler for the PreviewMouseDoubleClick event of the GridViewHeaderCell element. Then, in the new handler, if the e.OriginalSource is of the type Border, set the e.Handled property to True.

The following code snippet shows this suggestion's implementation:

this.AddHandler(GridViewHeaderCell.PreviewMouseDoubleClickEvent, new MouseButtonEventHandler(OnPreviewMouseDoubleClick));

private void OnPreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    if (e.OriginalSource is Border)
    {
        e.Handled = true;
    } 
}

The produced result is as follows:

Could you give this suggestion a try and let me know how it goes?
