  I have a radgrid and use a custom filter instead of the regular filter provided with the radgrid.  The filter is a radcombobox.  The datasource for the radgrid is a SQLDataSource.  The select statement for it is: select car_make, car_model from cars.  The datasource for the radcombobox is a SQLDatasource.  The select statement for it is: select distinct car_make from cars.  Obviously, the radcombobox is the filter for the car_make column.
  
  Well, this works fine, unless I have used the filter and it only returns one row, and I attempt to delete that row.  Upon trying to delete it, I get the error:
  
  Message: Sys.WebForms.PageRequestManagerServerErrorException: Selection out of range
  Parameter name: value
  
  Once I refresh the page, the custom filter is no longer being used, and the row was in fact deleted.
  
  Anyone have any ideas on how to keep the error from happening??
  
  Thanks in advance,
  
  Joshua

  Hi Joshua,
  
  Could you provide your aspx mark-up and code-behind (please, use the CodeFormatter tool of the editor to paste the code) or alternatively open up a formal support ticket and send a small test project to debug. It is important to know how you are creating the grid structure and binding the control.
  
  Thank you.
  
  Best wishes,

  I have discovered the exact same problem.
  
  I have a radgrid filtered by a (Hospital) combobox. If the filter only returns 1 matching item and then I modify the Hospital in that record (effectively removing the match) I get the error: Sys.WebForms.PageRequestManagerServerErrorException: Selection out of range when I return to the grid. This does not occur when there are matching items left.
  
  The relevant RadGrid code is:

  <telerik:GridBoundColumn DataField="Hospitalname" HeaderText="Hospital" SortExpression="Hospitalname"

      UniqueName="Hospitalname" CurrentFilterFunction="Contains" AutoPostBackOnFilter="true">

      <FilterTemplate>

          <telerik:RadComboBox ID="RadComboBoxTitle" DataSourceID="ds_Hospitals" DataTextField="Hospitalname"

              DataValueField="Hospitalname" AppendDataBoundItems="true" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Hospitalname").CurrentFilterValue %>'

              runat="server" OnClientSelectedIndexChanged="TitleIndexChanged">

              <Items>

                  <telerik:RadComboBoxItem Text="All" />

              </Items>

          </telerik:RadComboBox>

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

              <script type="text/javascript">

                  function TitleIndexChanged(sender, args) {

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

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

                  }

              </script>

          </telerik:RadScriptBlock>

      </FilterTemplate>

  </telerik:GridBoundColumn>

  My SQLDataSource is:

  <asp:SqlDataSource ID="ds_Hospitals" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

      SelectCommand="SELECT DISTINCT Hospitals.Hospitalname FROM Sub_Cases INNER JOIN Hospitals ON Sub_Cases.HospID = Hospitals.HospID WHERE Sub_Cases.UserID = @UserID">

      <SelectParameters>

          <asp:CookieParameter CookieName="UserID" Name="UserID" Type="Int32" />

      </SelectParameters>

  </asp:SqlDataSource>

  
  The edit function is being performed in a RadWindow (different page) and when the window is closed a JS function rebinds the grid.
  
  I did some testing on the other filters and discovered that the error only occurs when filtered by a RadComboBox (ie: if i filter by date and then change the date on the only matching record, the grid correctly shows the No Records Template).

  Hi GlenB,
  
  Have you compared your implementation with this presented in the following online demo of the product:
  
  http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx
  
  Can you outline the differences between this case and your configuration? They can lead us to the source of the problem to address it accordingly.
  
  Kind regards,

  The difference between the 2 is that in your demo there is no way to remove or edit a filtered item to reproduce the error. Otherwise for the purposes of the error I am getting there is no difference!
  
  Can you please try filtering a radgrid using a combobox and then remove the last matching record and see what happens - I am sure you will reproduce the fault.

  Hello Glen,
  
  Based on this information, it is hard to determine what is causing this error. If the issue persists, you can open a formal support ticket, and send us a small working project, demonstrating your setup, and the unwanted behavior. We will review it locally, and advise you further.
  
  All the best,
