Hi Mohan,

Thank you for writing.

When you right click a row in RadGridView it will automatically be selected, so your condition will always be satisfied and the context menu will always be opened. However, for your convenience, here is how to access the clicked row and its properties while opening the context menu:

void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    GridDataCellElement dataCell = e.ContextMenuProvider as GridDataCellElement;
    if (dataCell != null)
    {
        e.Cancel = !dataCell.RowInfo.IsSelected;
    }
}

I hope that you find this information useful.
 
All the best,

Hey there,

Wanted to thank you for including this code snippet - it took a little bit to find the solution for my issue.

Although the row is selected upon the right-click action, there are still cases where you need to use the code provided. An example is when you only want to modify the context menu for a given row type (i.e. you only want to modify the context menu for data rows and not filter/header rows). With this code, I was able to compare the type of e.ContextMenuProvider to only modify the context menu for data rows. This could easily be modified to be able to only modify context menus for other types such as header rows, filter rows and new rows.

Dim menuItem As RadMenuItem = Nothing
Dim menuSeperator As RadMenuSeparatorItem = Nothing

' modify the context menu of grid view data rows (i.e. not the header/filter/etc. rows)
If TypeOf e.ContextMenuProvider Is GridDataCellElement Then

    If e.ContextMenu.Items.Count > 0 Then
        menuSeperator = New RadMenuSeparatorItem
        e.ContextMenu.Items.Add(menuSeperator)
    End If

    menuItem = New RadMenuItem("View BOM")
    AddHandler menuItem.Click, AddressOf OnContextMenuClicked_ViewBom
    e.ContextMenu.Items.Add(menuItem)

    menuItem = New RadMenuItem("Edit BOM")
    AddHandler menuItem.Click, AddressOf OnContextMenuClicked_EditBom
    e.ContextMenu.Items.Add(menuItem)

End If

Thanks again!
