Hey,

We have a Grid with a few columns that we want to filter with the unique values from the field. We are using a FilterTemplate to do it (based on example from Telerik). The filtering is working fine, but when we are trying to export to PDF we are getting this error:

Unable to cast object of type 'Telerik.Web.Apoc.Layout.BlockArea' to type 'Telerik.Web.Apoc.Layout.AreaContainer'



Also, when exporting to excel you can see the attached screenshot from the output file.



This is the FilterTemplate content:



<FilterTemplate>

 <telerik:RadComboBox ID="cboStatus1" DataSourceID="sdsStatus" DataTextField="STATUSDESCRIPTION"

  DataValueField="STATUSDESCRIPTION" Height="100px"

  AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("STATUSDESCRIPTION").CurrentFilterValue %>'

  runat="server" OnClientSelectedIndexChanged="Assessment_StatusIndex"

  Skin="Metro">

  <Items>

   <telerik:RadComboBoxItem Text="All" />

  </Items>

 </telerik:RadComboBox>

 <telerik:RadScriptBlock ID="RadScriptBlock2" runat="server">

  <script type="text/javascript">

   function Assessment_StatusIndex(sender, args) {

    var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

    tableView.filter("STATUSDESCRIPTION", args.get_item().get_value(), "EqualTo");

   }

  </script>

 </telerik:RadScriptBlock>

</FilterTemplate>



Thanks,

Mano
