Grid export error when groups are created in code behind

We are using WebUI Studio 2009 R2 with all fixes.

We have grid with 10 columns defined on the aspx page. First 2 columns have Visible="false".

In code-behind, in the WebGrid1_InitializeLayout event, 2 groups are created and their ColumnMember are those 2 hidden columns.

When I select Export on the grid, an alert is shown with text - Column "Column1" not found.

I tried to set those columns visible in the WebGrid1_Export :

protected void WebGrid1_Export(object sender, ISNet.WebUI.WebGrid.ExportEventArgs e)
        {
            e.Table.Columns.GetNamedItem("Column1").Visible = true;
        }

If I try to export, another alert is shown with text - Object reference not set to an instance of an object.

On the other hand, if groups are defined on the aspx page in the <GroupedColumns> section of the grid, everything works fine.

We have around 10+ different pages with grid. Each page has grid that generates groups based on UrlParameter and different UrlParameter values can be between 2 and 8 per page. That means that those 10+ pages wih dynamically generated groups replace between 40 and 60 statically defined aspx pages.

Is there a way to make export work with groups defined in code-behind?
