Hi

In the code below, which I found at the bottom of the following page
http://www.codeproject.com/Questions/518882/vb-net-2cplusDatagridViewplusContextplusMenuplusSt

The Context Menu Strip isn't showing. How do I get it to pop up at the right click point
and how do I run code to delete a cell?
 

Private Sub DgvDelays_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DgvDelays.CellMouseDown
        Dim rowClicked As DataGridView.HitTestInfo = DgvDelays.HitTest(e.X, e.Y)
 
        'Select Right Clicked Row if its not the header row
        If e.Button = Windows.Forms.MouseButtons.Right AndAlso e.RowIndex > -1 Then
            'Clear any currently sellected rows
            DgvDelays.ClearSelection()
            Me.DgvDelays.Rows(e.RowIndex).Selected = True
            CmsRightClick.Show(DgvDelays, New System.Drawing.Point(MouseX, MouseY))
        End If
 

    End Sub

The code provided in the article you point to is incomplete. See the comments at the bottom of the page.

I suspect that CmsRightClick is a ContextMenuStrip, but it is not defined anywhere in the code.

Thanks James. How do I get it to pop up with a button on it that runs some code?

I do not understand your last question.

What do you want to pop up? A ContextMenuStrip? There are no "buttons" on a ContextMenuStrip, only menu items.

Do you already have a ContextMenuStrip on your form?

Once you have a ContextMenu on the form, you must :

1. Click on the menu in the component tray (bottom of the form). The menu will appear temporarily where the standard menu usually shows, at the top of the form. With a right click in that menu, you will be able to add entries for the menu. A double click on an entry will enable you to react to the Click event on that entry.

2. To associate the context menu with a given control, such as a TextBox, click on the TextBox in the designer, and then, under the ContextMenuStrip property, in the Properties window, select the menu that you want to associate with that TextBox.

The menu will automatically show when the user right-click on the TextBox.
