[Solved] Help with Grid Filter

[Ryan]

I have this grid filter that stopped working.  I have about 6-10 of these filters on the grid and just this one stopped working.  Any suggestions??

<telerik:GridBoundColumn DataField="AssignedTo"
            FilterControlAltText="Filter AssignedTo column" HeaderText="AssignedTo"
            SortExpression="AssignedTo" UniqueName="AssignedTo">


            <FilterTemplate>
                <telerik:RadComboBox ID="RadComboBoxAssignedTo" DataSourceID="SqlDataSource4" DataTextField="UserName"
                    DataValueField="UserName" Height="150px" Width="100px" AppendDataBoundItems="true" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("AssignedTo").CurrentFilterValue %>'
                    runat="server" OnClientSelectedIndexChanged="AssignedToIndexChanged">
                    <Items>
                        <telerik:RadComboBoxItem Text="All" />
                    </Items>
                </telerik:RadComboBox>
                <telerik:RadScriptBlock ID="RadScriptBlock3" runat="server">

                    <script type="text/javascript">
                        function AssignedToIndexChanged(sender, args) {
                            var tableView = $find("<%# TryCast(Container,GridItem).OwnerTableView.ClientID %>");
                            tableView.filter("AssignedTo", args.get_item().get_value(), "EqualTo");
                        }
                    </script>

                </telerik:RadScriptBlock>
            </FilterTemplate>

        </telerik:GridBoundColumn>

Here is the error I am getting.

Hi Ryan,

Please try to set the SelectedValue of RadComboBox not declaratively, but in code behind:

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
  If TypeOf e.Item Is GridFilteringItem Then
    'Access the filter combobox
    combo.SelectedValue = e.Item.OwnerTableView.GetColumn("AssignedTo").CurrentFilterValue
  End If
End Sub

Thanks,
Shinu

Visual studio is yelling about "combo.SelectedValue="

Why would 1 of 10 filters start doing this?

[Ryan]

Also, these were made using this example.

http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx

its weird that 1 out of 10 has this issue.

Not sure why this worked, but I changed UniqueName="AssignedTo" to something like UniqueName="unqAssignedTo" and changed all the spots it was referenced and it started working.  This unique name is not used anywhere else, so I am not sure why it all of the sudden started working.  Just thought I would share.
