Problem using FilterTemplate with JS

[Nikola]

Story:

I'm trying to do some filtering with JavaScript I'have a grid and in this grid I want to filter some values using Combo Boxes . So far the values are displayed in the Combo Boxes etc.. and it is already working for one .

Question:

My problem is don't get it why is it not working for my second example.. I always get this strange error

The argument types 'Edm.Int32' and 'Edm.String' are incompatible for this operation. Near equals expression, line 6, column 19.

This example works fine

                <telerik:GridTemplateColumn DataField="ActivityId" FilterControlAltText="Filter ActivityId column"
                    HeaderText="Activity" SortExpression="ActivityId" UniqueName="ActivityId">
                    <ItemTemplate>
                        <asp:Literal runat="server" Text='<%# Eval("Activity.FullActivity") %>' />
                    </ItemTemplate>
                    <FilterTemplate>
                        <telerik:RadComboBox runat="server" DataSourceID="dsActivity" DataTextField="FullActivity" DataValueField="ActivityId"
                            SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("ActivityId").CurrentFilterValue %>'
                            Height="200px" AppendDataBoundItems="true" OnClientSelectedIndexChanged="TitleIndexChanged">
                            <Items>
                                <telerik:RadComboBoxItem Value="0" Text="- All -" />
                            </Items>
                        </telerik:RadComboBox>
                        <telerik:RadScriptBlock ID="rsbActivity" runat="server">
                            <script type="text/javascript">
                                function TitleIndexChanged(sender, args) {
                                    //alert(args.get_item().get_value());
                                    if (args.get_item().get_value() > 0) {
                                        var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                        tableView.filter("ActivityId", args.get_item().get_value(), "EqualTo");
                                    } else {
                                        tableView.filter("ActivityId");
                                    }
                                }
                            </script>
                        </telerik:RadScriptBlock>
                    </FilterTemplate>
                </telerik:GridTemplateColumn>

And in this one its not working ...

   <telerik:GridTemplateColumn DataField="Dossier.LBUId" HeaderText="LBU" FilterControlAltText="Filter Dossier.LBUId column"
                            SortExpression="LBUId" UniqueName="LBUId">
                            <ItemTemplate>
                                <asp:Literal ID="Literal3" runat="server" Text='<%# Eval("Dossier.LBU.Code") %>' />
                            </ItemTemplate>
                            <FilterTemplate>
                                <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="dsLBU" DataTextField="Code" DataValueField="LBUId"
                                    SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("LBUId").CurrentFilterValue %>'
                                    Height="200px" AppendDataBoundItems="true" OnClientSelectedIndexChanged="ChangeLbuCode">
                                    <Items>
                                        <telerik:RadComboBoxItem Value="0" Text="- All -" />
                                    </Items>
                                </telerik:RadComboBox>
                                <telerik:RadScriptBlock ID="ChangeLbuCode" runat="server">
                                    <script type="text/javascript">

                                        function ChangeLbuCode(sender, args) {
                                            if (args.get_item().get_value() > 0) {
                                                var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                                tableView.filter("LBUId", args.get_item().get_value(), "EqualTo");
                                            } else {
                                                tableView.filter("LBUId");
                                            }
                                        }
                                    </script>
                                </telerik:RadScriptBlock>
                            </FilterTemplate>
                        </telerik:GridTemplateColumn>

Thanks for help and fast answer !!

Hi Nikola,

You need to have consistent datatype. Check the values and datatype in the ComboBox dataSet and what you pass in the parameter of the  RadGrid's DataSource and verify if they are equal.

All the best,
