Detect the column header region in the mouse down event of a grid

created 13 years ago

I need to detect if the mouse is over the column headers and suppress my custom pop-up menu. The built in popup menus displays together with mine. I want to suppress my pop-up and show the grid header popup menu only. How would I do that?

I'm using this code:

Private Sub GridControl1_MouseDown(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles GridControl1.MouseDown
'MsgBox(e.Location.ToString)
'have to take into account nav3 dimensions hosting form
'lets suppress this for awhile
Dim x As Integer = e.X + Nav3.NavBarControl1.Width
Dim y As Integer = e.Y + Nav3.RibbonControl.Height
Dim p As New System.Drawing.Point(x, y)

If e.Button = Windows.Forms.MouseButtons.Right Then
Me.PopupMenu1.ShowPopup§
End If
End Sub

    Construct a GridHitInfo object; this will tell you if the user is pressing the mouse down on a column header, group panel etc…

    C#
    private void gridView1_MouseDown(object sender, MouseEventArgs e)  
{  
    GridHitInfo hitInfo = gridView1.CalcHitInfo(e.Location);  

    if (hitInfo.InColumnPanel)  
    {  
        //do something  
    }  
}

        Hi Brendon,
        Thank you for a quick and accurate response, I have included my code for vb.net users who may be using a banded grid.
        Private Sub GridControl1_MouseDown(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) _
         Handles GridControl1.MouseDown
                If e.Button = Windows.Forms.MouseButtons.Right Then

        Dim hitinfo As DevExpress.XtraGrid.Views.BandedGrid.ViewInfo.BandedGridHitInfo = AdvBandedGridView1.CalcHitInfo(e.Location)
                    If hitinfo.InRow Or hitinfo.InRowCell Then

        'have to take into account nav3 dimensions
                        Dim x As Integer = e.X + Nav3.NavBarControl1.Width + 5 'splitter bar
                        Dim y As Integer = e.Y + Nav3.RibbonControl.Height + 33 'lbl at top
                        Dim p As New System.Drawing.Point(x, y)
                        Me.PopupMenu1.ShowPopup§
                    Else
                        'use builtin popups
                    End If
                End If
            End Sub
