    Hi all,

    Right now, I am facing a problem with my Filter Template.
    I have studied this  link http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx .
    It is good example.
    But my problem is that one of my column has some different condition.
    The combo box has 4 value (i.e. New, In Progress, Near completion, Closed). it is filled by data source SDSStatus & two more items are added i.e. "All" & "Open Only".
    Now, Suppose If I am select Open Only from combo,except "Closed" records all other records should be displayed in grid. 
    Actually, I want to know that, Is it possible to filter like this way? 
    Please help me its urgent.
    see below code.  ( That is what I am thinking ).

    <telerik:GridBoundColumn DataField="StatusName" HeaderText="Status Name" SortExpression="StatusName"
                                      UniqueName="StatusName"  >
                                      <FilterTemplate>
                              <telerik:RadComboBox ID="RadComboBoxSts" DataSourceID="SDSStatus" DataTextField="StsName"
                                  DataValueField="StsName" Skin="Office2007" Width = "100%" Height="100px" AppendDataBoundItems="true" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("StatusName").CurrentFilterValue %>'
                                  runat="server" OnClientSelectedIndexChanged="StsIndexChanged">
                                  <Items>
                                      <telerik:RadComboBoxItem Text="All"/>
                                                   <telerik:RadComboBoxItem Text="Open Only"/> 
                                  </Items>
                              </telerik:RadComboBox>
                              <telerik:RadScriptBlock ID="RadScriptBlock3" runat="server">
     
     
                                  <script type="text/javascript">
                                      function StsIndexChanged(sender, args) {
                                                         
                                      var tableView = $find("<%# TryCast(Container,GridItem).OwnerTableView.ClientID %>");
     
                                    If(args.get_item().get_text() == "Open Only")
                                                      {
                                          tableView.filter("TaskTypeName", "Closed", "NotEqualTo");
                                                       // Combo selected text must be Open Only after filtering.
                                                       }
                                       Else
                                                        {
                                          
                                          tableView.filter("TaskTypeName", args.get_item().get_value(), "EqualTo");
                                                        }  
                                      }
                                  </script>
     
     
                              </telerik:RadScriptBlock>
                          </FilterTemplate>
                                      <HeaderStyle  Width = "6%" VerticalAlign ="Top"/>
                                      <ItemStyle  Width = "6%" VerticalAlign ="Top"/>
                                  </telerik:GridBoundColumn>

    Hello Ronak,

    As long as the column is bound to a data field that contains the respective values, more specifically "Closed", it is fine to filter by them and your code seems to be correct for such case.
