use of RadDropDownTree in Filter

[Dennis]

HI Community 

 

does anyone have an example of using a RadDropDownTree in a Filter ? 

 i searched in the forum without a result :-( 

 

what i have so far :-) 

 

 <telerik:GridBoundColumn DataField="Problem_FK" DataType="System.Int32" FilterControlAltText="Filter Problem_FK column" HeaderText="Problem_FK" SortExpression="Problem_FK" UniqueName="Problem_FK" Display="true">
                            <FilterTemplate>
                                    <telerik:RadDropDownTree ID="ddtProb" runat="server" DataFieldID="prob_ID" DataFieldParentID="prob_ParentID" OnClientEntryAdded="ExpectedIndexChanged" DataSourceID="dsProblemTree" DataTextField="prob_Name" DataValueField="prob_ID" Height="16px" Width="361px">
                                    </telerik:RadDropDownTree>
                                <telerik:RadScriptBlock ID="rsbExpected" runat="server">
                                    <script type="text/javascript">
                                        function ExpectedIndexChanged(sender, args) {
                                            var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                            tableView.filter("Problem_FK", args.get_item().get_value(), "EqualTo");
                                        }
                                    </script>
                                </telerik:RadScriptBlock>
                            </FilterTemplate>
                    </telerik:GridBoundColumn>

Hello Dennis,

Could you test your sample by changing the args.get_item().get_value() part to a hardcoded value: for example, tableView.filter("Problem_FK", "Problem1", "EqualTo");.

Looking forward to your reply.
