RadFilterDataFieldEditor with FilterContainerID sets

[JiriSchmitt]

Hello,

I have created RadFilterDataFieldEditor by following article: http://www.telerik.com/community/forums/aspnet-ajax/filter/error-when-building-custom-radfilterdatafieldeditor.aspx
It works good if the FilterContainerID property is not set. If I set this property to my RadGrid it does not work correctly.
Editor is shown ok if I add filter expression, but after I click the Apply button, default editor is shown instead RadFilterDataFieldEditor. After next postback I get error with invalid viewstate data.

Here is the Code:

<telerik:RadFilter runat="server" ID="filter" FilterContainerID="articles" ShowApplyButton="true"
    OnFieldEditorCreating="filter_FieldEditorCreating">
    <FieldEditors>
        <telerik:RadFilterTextFieldEditor FieldName="Title" />
        <km:RadFilterDropDownEditor DataSourceID="dsStates" DataTextField="Name" DataValueField="ArticleStatusId"
            FieldName="StatusId" />
        <telerik:RadFilterTextFieldEditor FieldName="AuthorFullName" />
        <telerik:RadFilterNumericFieldEditor FieldName="Rating" />
        <telerik:RadFilterNumericFieldEditor FieldName="TimesRated" />
        <telerik:RadFilterDateFieldEditor FieldName="CreatedDate" />
        <telerik:RadFilterDateFieldEditor FieldName="ModifiedDate" />
    </FieldEditors>
</telerik:RadFilter>
<telerik:RadGrid ID="articles" runat="server" OnNeedDataSource="articles_NeedDataSource"
    EnableLinqExpressions="false" ShowFooter="True" AllowFilteringByColumn="True"
    AllowSorting="True" ShowGroupPanel="True" AllowPaging="true" PageSize="10">
    <MasterTableView AutoGenerateColumns="False" EnableHeaderContextMenu="true" IsFilterItemExpanded="false">
        <Columns>
            <telerik:GridBoundColumn DataField="Title" HeaderText="Title" />
            <telerik:GridDropDownColumn DataField="StatusId" HeaderText="Status" DataSourceID="dsStates" ListTextField="Name" ListValueField="ArticleStatusId" />
            <telerik:GridBoundColumn DataField="AuthorFullName" HeaderText="Author" />
            <telerik:GridBoundColumn DataField="Rating" HeaderText="Rating" />
            <telerik:GridBoundColumn DataField="TimesRated" HeaderText="TimesRated" />
            <telerik:GridBoundColumn DataField="CreatedDate" HeaderText="Created" />
            <telerik:GridBoundColumn DataField="ModifiedDate" HeaderText="Modified" />
        </Columns>
    </MasterTableView>
    <GroupingSettings ShowUnGroupButton="true" CaseSensitive="false" />
    <ClientSettings AllowDragToGroup="True" AllowColumnsReorder="True" />
</telerik:RadGrid>

Codebehind:

protected void filter_FieldEditorCreating(object sender, RadFilterFieldEditorCreatingEventArgs e)
{
    if (e.EditorType == "RadFilterDropDownEditor")
    {
        e.Editor = new RadFilterDropDownEditor();
    }
}

Thank you
Jiri

Hi Jiri,

I am afraid that with custom editors RadFilter does not support automatically filtering on container. You should manually apply the expressions to RadGrid. For your convenience I am attaching sample app demonstrating how to achieve this.
