Try This Code:(Using Gridcontrol Mouse Down Event)

VB.net:
 Dim hitInfo = GridView1.CalcHitInfo(e.Location)  
If e.Button = Windows.Forms.MouseButtons.Left Then 
    For Each column As GridColumn In GridView1.Columns  
       If column.FieldName = hitInfo.Column.FieldName Then 
            hitInfo.Column.AppearanceCell.BackColor = Color.FromArgb(226, 234, 253)                       
       Else
            GridView1.Columns(column.FieldName).AppearanceCell.BackColor = Nothing
       End If
    Next
End If

 C#: 
var hitInfo = GridView1.CalcHitInfo(e.Location);
if (e.Button == Windows.Forms.MouseButtons.Left) 
{
    foreach (GridColumn column in GridView1.Columns) 
    {
       if (column.FieldName == hitInfo.Column.FieldName) 
        {
            hitInfo.Column.AppearanceCell.BackColor = Color.FromArgb(226, 234, 253);
        }
        else 
        {
        GridView1.Columns(column.FieldName).AppearanceCell.BackColor = null;
        }
    }
}

The GridView.CalcHitInfo method is called to obtain a row handle. Focus is then moved to this row and the custom context menu called.
