Hi,

we evaluate the RadGrid as our new standard Grid. Everytime I export my grid to pdf (csv, word and excel works well) I get this error:

System.InvalidCastException: Unable to cast object of type 'Telerik.Web.Apoc.Layout.BlockArea' to type 'Telerik.Web.Apoc.Layout.AreaContainer'. at Telerik.Web.Apoc.Fo.Flow.BlockContainer.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.Block.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.TableCell.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.TableRow.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.AbstractTableBody.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.Table.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.Block.Layout(Area area) at Telerik.Web.Apoc.Fo.Flow.Flow.Layout(Area area, Region region) at Telerik.Web.Apoc.Fo.Flow.Flow.Layout(Area area) at Telerik.Web.Apoc.Fo.Pagination.PageSequence.Format(AreaTree areaTree) at Telerik.Web.Apoc.StreamRenderer.Render(PageSequence pageSequence) at Telerik.Web.Apoc.Fo.FOTreeBuilder.EndElement() at Telerik.Web.Apoc.Fo.FOTreeBuilder.Parse(XmlReader reader)


I'm using the RadGrid the ASP.NET AJAX Q1 2010 version (Telerik.Web.UI Trial Version 2010.1.309.20).

Can anyone confirm my problem and suggest a solution?

Appreciate your help! Kind regards,
Michael

Hello Michael,

Please try to remove GridPagerItem and GridFilteringItem before export:
bool isExport = false;
protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToExcelCommandName || e.CommandName == Telerik.Web.UI.RadGrid.ExportToWordCommandName || e.CommandName == Telerik.Web.UI.RadGrid.ExportToCsvCommandName || e.CommandName == Telerik.Web.UI.RadGrid.ExportToPdfCommandName)
    {
        isExport = true;
        ConfigureExport();
    }
}
protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
if (isExport && (e.Item is GridPagerItem || e.Item is GridFilteringItem))
    e.Item.Visible = false;
}
