Version Upgrade Issue

[林]

private void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    var cellElement = e.ContextMenuProvider as GridCellElement;
    if (cellElement == null) return;
    if (cellElement is GridHeaderCellElement)
    {
      RadMenuItem exportExcel = new RadMenuItem($"ExportToExcel");
      exportExcel.Click += (s, args) => { ExportToExcel(); };
      e.ContextMenu.Items.Add(exportExcel);
    }
}
After upgrade to UI.for.WinForms.AllControls.Net80 <Version>2025.4.1321
cellElement is null in the above line 
then return 
i can not see "RadMenuItem($"ExportToExcel")"
WHY？

Hello,

Thank you for providing your code snippet regarding ContextMenuOpening event.

In version 2025.4.1321, we introduced an optimization to improve the display of the context menu. With this change, when a user clicks a column header cell, the ContextMenuProvider is now the GridViewColumn rather than the GridHeaderCellElement (as it was before). This adjustment ensures that the context menu displayed corresponds specifically to the selected column (rather than cell), matching the user's expectations.

Now, you need to adjust your code snippet a little and check for GridViewColumn. Thus, the ExportToExcel option will show every time you click on a column header, and it will continue to work as before:

private void RadGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    var column = e.ContextMenuProvider as GridViewColumn;
    if (column == null) return;

    if (column is GridViewColumn)
    {
        //if you click on a column header, then show ExportToExcel option
        RadMenuItem exportExcel = new RadMenuItem($"ExportToExcel");
        exportExcel.Click += (s, args) => { ExportToExcel(); };
        e.ContextMenu.Items.Add(exportExcel);
    }
}

I hope this information helps. Please let me know if you have any other questions.
