Error with RadFilter in RadWindow

[Marc St-Laurent]

Hello,

I have a page that contains a RadGrid, and I would like to be able to open a RadWindow which contains a RadFilter for the grid.  My current implementation has all 3 objects on the same page (Default.aspx).  The RadWindow does not open a new URL, instead it contains the RadFilter in a ContentTemplate declaration:

<!-- The window opened by the "Filter Builder" toolbar button -->
    <telerik:RadAjaxPanel runat="server" ID="WindowAjaxPanel">
        <telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
                runat="server" Skin="Office2007">
            <Windows>
                <telerik:RadWindow ID="FilterBuilderWindow" runat="server" Behaviors="Close" Title="Filter Builder"
                        Width="350" Height="350" EnableViewState="true">
                    <ContentTemplate>
                        <asp:Panel ID="FilterContentPanel" runat="server" CssClass="filterDialogContent">
                            <asp:Panel ID="FilterPanel" runat="server" CssClass="filterTree">
                                <telerik:RadFilter runat="server" ID="FilterControl" RegisterWithScriptManager="true"
                                        FilterContainerID="OrderFulfillmentGrid"
                                        ShowApplyButton="false" Skin="Office2007"/>
                            </asp:Panel>
                            <asp:Panel ID="FilterButtonPanel" runat="server" CssClass="filterButtonPanel">
                                <asp:Button runat="server" ID="filterBuilderOK" OnClick="filterBuilderOK_Click" Text="OK" />
                                <asp:Button runat="server" ID="filterBuilderCancel" Text="Cancel"
                                        OnClick="filterBuilderCancel_Click" />
                                <asp:Button runat="server" ID="filterBuilderApply" OnClick="filterBuilderApply_Click"
                                        Text="Apply" />
                            </asp:Panel>
                        </asp:Panel>
                    </ContentTemplate>
                </telerik:RadWindow>
            </Windows>
        </telerik:RadWindowManager>
    </telerik:RadAjaxPanel>

The RadWindow is opened with the following javascript:

// Open the Filter Builder dialog
function openFilterBuilderDialog() {
    window.radopen(null, "FilterBuilderWindow");
    return false;
}

The window opens just fine, and the RadFilter appears normally.  The problem is that as soon as I press the "Add expression" button on the RadFilter, the following error is thrown:

Erreur du serveur dans l'application '/'.

Translation of the error message: The index was out of bounds.  It cannot be negative, and must be less than the size of the collection.  Parameter name: index.

I have tried too many variations on the above code to count, and I'm all out of ideas.  Your help is greatly appreciated.
Thanks in advance,
Marc

Hello Marc,

For your convenience I am attaching sample application demonstrating how to filter RadGrid using RadFilter when it is placed inside RadWindow.

Hello,

Thank you very much for your assistance.  I modified my code with the help of the example you sent, but the error persisted.  I figured it out, though.  It was caused by the fact that the grid and the window were not declared inside the same Content tag.  Once I moved them together, all started working.

I did notice one little thing though: When I click on the "Add expression" button the first time, the click does register, but nothing seems to happen.  It does work on the 2nd click.  Have there been any reports of this kind of behavior?

Thanks,
Marc

Hello Marc St-Laurent,

Unfortunately when placing the controls in different ContentPlaceHolder is not supported as ContentPlaceHolders are naming containers. You can experience same behavior by placing some bound control(GridView/ListView) in one place holder and its DataSourceControl into another place holder.

Regarding the second beahvior you should not use RadWindowManager when using ContentTemplate and RadAjaxManager. For more details please refer to the description on the demo bellow:
