Adding filter to GridDropDownColumn on Insert

[Shivek]

Hi all,

 

I've managed to add a filter on a dropdown column in my grid, which allows me to easily look for the correct data in my list. But the issue here is that I cannot filter the list with the filter option "Contains". It always returns me the "EqualTo" values. I need it to work with Contains.

Here is my code:

<telerik:RadGrid ID="GridOffences" runat="server" DataSourceID="GETOffence" RenderMode="Auto" AutoGenerateColumns="False" ShowFooter="true" OnItemDataBound="GridOffences_ItemDataBound" OnItemCommand="GridOffences_ItemCommand" OnUpdateCommand="GridOffences_UpdateCommand" OnInsertCommand="GridOffences_InsertCommand">

    <MasterTableView AutoGenerateColumns="False" DataKeyNames="offId" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add Offence" AllowSorting="false">
        <CommandItemSettings ShowAddNewRecordButton="true" ShowRefreshButton="false"
                                                        ShowExportToCsvButton="false" ShowExportToExcelButton="false" ShowExportToPdfButton="false" ShowExportToWordButton="false" />
        <EditFormSettings>
            <EditColumn UniqueName="EditColumnColumn" ButtonType="PushButton" EditText="Edit" CancelText="Cancel" InsertText="Add" UpdateText="Save"></EditColumn>
        </EditFormSettings>
        <Columns>
            <telerik:GridDropDownColumn DataSourceID="GETOffenceList" ListTextField="offName" ListValueField="offListId"
                UniqueName="offNameList" HeaderText="Offence" DataField="offListId"
                AllowAutomaticLoadOnDemand="true" DropDownControlType="RadComboBox"
                AllowVirtualScrolling="true" ShowMoreResultsBox="true" ItemsPerRequest="10">
                <ColumnValidationSettings EnableRequiredFieldValidation="true" EnableModelErrorMessageValidation="true">
                    <RequiredFieldValidator ForeColor="Red" ErrorMessage="This field is required"></RequiredFieldValidator>
                    <ModelErrorMessage BackColor="Red" />
                </ColumnValidationSettings>
                <FilterTemplate>
                    <telerik:RadComboBox ID="RadCbox_File" runat="server" DataSourceID="GETOffenceList" DataTextField="offName"
                                DataValueField="offListId" Filter="Contains"
                                AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("offListId").CurrentFilterValue %>'
                                OnClientSelectedIndexChanged="FileComboIndexChanged">
                        <Items>
                            <telerik:RadComboBoxItem Text="Select an Offence" />
                        </Items>
                    </telerik:RadComboBox>
                    <telerik:RadScriptBlock ID="RadScriptFiles" runat="server">
                        <script type="text/javascript">
                            function FileComboIndexChanged(sender, args) {
                                var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
                                tableView.filter("offListId", args.get_item().get_value(), "Contains");
                            }
                        </script>
                    </telerik:RadScriptBlock>
                </FilterTemplate>
            </telerik:GridDropDownColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

 

Thanks in advance for your help

Hi Ouzayr,

Make sure that you are using the latest release version of the controls. Also, you can set the CurrentFilterFunction property of the column to Contains.

I suppose you want to achieve something similar to the implementation demonstrated in the following live sample:
http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx

You can also examine the first web site from this post:

I hope this will prove helpful.

Hello Eyup,

Thank you for your response. I've finally added the filter on server side.

Best Regards
