Hi,

I tried to set a default-Filter-Value in my FilterTemplate.
But my Default-Item doesn´t work as well... The filtering still shows "ALL" items

I need to set the default filter-value as "bearbeitung" (translation: in process)

With "<DefaultItem Text="Bearbeitung" Value="Bearbeitung"/>" it shows the correct value at the combobox.
But still shows all items.

If i choose the value "Bearbeitung" manually from the RadComboBox, the filtering works fine.

<telerik:GridBoundColumn AllowFiltering="true" FilterControlWidth="100px" DataField="TicketStatusBezeichnung" HeaderText="Ticket Status" ShowFilterIcon="true"  AutoPostBackOnFilter="true"><br>                    <FilterTemplate>
<
telerik:RadComboBox  ID="RadComboBoxTicketStatus" DataSourceID="SqlDataSource2" DataTextField="TicketStatusBezeichnung"<br>                            DataValueField="TicketStatusBezeichnung" Height="200px" AppendDataBoundItems="true"  SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("TicketStatusBezeichnung").CurrentFilterValue %>'<br>                            runat="server" OnClientSelectedIndexChanged="TitleIndexChanged" Sort="Descending"><br>                            <DefaultItem Text="Bearbeitung" Value="Bearbeitung"/><br>                            <Items><br>                                <telerik:RadComboBoxItem Text="Alle" /><br>                            </Items><br>                        </telerik:RadComboBox><br>                        <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server"><br>                            <script type="text/javascript"><br>                                function TitleIndexChanged(sender, args) {<br>                                    var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");<br>                                    tableView.filter("TicketStatusBezeichnung", args.get_item().get_value(), "EqualTo");<br>                                }<br>                            </script><br>                        </telerik:RadScriptBlock><br>                    </FilterTemplate><br>               
</
telerik:GridBoundColumn>

Thanks in advance :)

best,
Marc B

Hi Marc,

In order to set a filter that will be applied initially to RadGrid you can use the following approach:

  • Handle the PreRender event of RadGrid
  • Use the handler to set the FilterExpression property
  • Rebind RadGrid

The approach is also illustrated in the article linked below.

Hi Shakeel,

Please check out the documentation shared by Viktor and follow the instructions. The filtering will be applied properly.

If the results are not what you expect, you will need to verify the database records and or the filter expression you use to filter the Grid.
