Hello anu,

I have tried this with just a panel, and realised that this would cause some issues. For exmaple, if you scroll the grid, then the panel would stay in the same place, it would be hidden if you click on a button at the bottom of the grid and so on. Taking this into account, I think it is best to use the Telerik RadContextMenu and dynamically add the panel to the context menu. This gets over these issues and the context menu will then render in the correct place, even placing the panel outside of the bounds of the form if required.
The only part that I haven't yet solved is that there is a RadScrollViewer that creates the look of a right border on the panel, however, this seems to be the most elegant solution I can think of at the moment.

Here is the full code: (Just a grid on a form)

Designer File:

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _

Partial Class Form1

Inherits System.Windows.Forms.Form

'Form overrides dispose to clean up the component list.

<System.Diagnostics.DebuggerNonUserCode()> _

Protected Overrides Sub Dispose(ByVal disposing As Boolean)

Try

If disposing AndAlso components IsNot Nothing Then

components.Dispose()

End If

Finally

MyBase.Dispose(disposing)

End Try

End Sub

'Required by the Windows Form Designer

Hi Richard,

I'm confusing with this vb code, can u please explain this using c sharp. I'm also facing the same problem to get the x/y coordinates of a selected row.

Actually my problem is,

I have a radgrid with a delete Imagebutton, when i click on delete button a panel should hide that row with corresponding height and width of that row and the panel should contain two buttons with confirmation message... I'm using a jquery function to display the panel as slidedown when i click on delete button. this is my code to slidedown that panel

<script type="text/javascript">
        $(function () {
            $("#Link1").click(function (evt) {
                evt.preventDefault();
                $('#panelText').slideToggle('slow');
            });
        });

    </script>

can u please tell me how to display the panel on the selected row... and how to call that jquery function
