FilterTemplate - RadComboBox Default Value

[Marc]

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,

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.

• Applying default filter on initial Load
