Hello salini,

I am not able to reproduce the issue following the supplied information. Could you illustrate how you disable the right click? It will be best if you can share with us the code snippets which demonstrate your approach.

I am looking forward to your reply.

Hello,

Also, ensure that you are not handling the ContextMenuOpening event and clearing the context menu as below.

Private Sub RadGridView1_ContextMenuOpening(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles RadGridView1.ContextMenuOpening
    e.ContextMenu.Items.Clear()
End Sub

hi,

i have used the radGridView event "ContextmenuOpening" to set up a custom context menu..
(e.contextmenu = myowncontextmenu..)
however i wish the default context menu to appear when the row clicked is the header row or filter row
of the radGridView
any idea on how to get the default context menu back ?
:)

Hello Norma,

In order to show a custom menu just if the the selected cell is a data cell you should check the context menu provider, like so:
void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    if (e.ContextMenuProvider is GridDataCellElement)
    {
        // show Custom menu
    }
}

Hope this helps, if you have any other questions or comments, please let me know,

hi Emanuel

thank you for your reply
but.. i actually was trying to ask something else:

once i set the grid view context menu to some custom menu i have created myself
i loose the default grid view context menu, (the telerik one - with all the sorting and filtering options)

my question was - how do i get the telerik default gridview context menu back?
i want to show it (instead of my own custom menu) when the user clicks on the grid view filter row.

another problem i have is that once i set the context menu to the one i have created myself
clicking the filter symbol which appears on each cell of the filter row - also does not open the default menu as it did before.

sorry i was not clear before :)

Hi Norma,

I'd like to clarify what it is you would like to do as there seems to be some conflicting requests.

From what I can tell, you would like to provide your own context menu under some circumstances, and the default context menu under other circumstances. Please could you clarify when, and on which row types you would like your own context menu Vs the default one, or indeed, a mixture of the two. This way I can prepare a sample that is correct for your needs.

Many thanks
Richard

Hello Norma,

You are not losing it, every time the context menu required event fires you are clearing out the old items or providing a new menu, just don't do that anymore and don't cancel the event and you will have the default menu back.

Hope this helps, if you have any other questions or comments, please let me know,

Hi norma,

In addition to Emanuel's answer, you can use the following code snippet that demonstrates how you should modify the context menu without affecting the dynamic building of the header's context menu:

void radGridView1_ContextMenuOpening(object sender, Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)
{
    GridCellElement cellElement = e.ContextMenuProvider as GridCellElement;
 
    if (cellElement == null || cellElement.RowInfo is GridViewFilteringRowInfo || cellElement.RowInfo is GridViewTableHeaderRowInfo)
    {
        return;
    }
 
    RadDropDownMenu menu = new RadDropDownMenu();
    menu.Items.Add(new RadMenuItem("Hello"));
    e.ContextMenu = menu;
}

I hope this helps.

Best wishes,
Svett
