Hi,

I try to implement deleting a row with Ajax, similar to this example: http://samples.infragistics.com/2010.3/WebFeatureBrowser/srcview.aspx?path=WebHierarchicalDataGrid/WebHierarchicalDataGrid_DeletingParentRow.src

When I click the Delete button I receive: "Async response failure: equest.readyState == 4". I use Version=10.3.20103.2013.

Sample code:

    <ig:WebHierarchicalDataGrid ID="whdg" runat="server" Height="400px"
        Width="700px" HeightAutoGenerateBands="False" AutoGenerateColumns="False" Key="LLL"
        AutoGenerateBands="False" DataKeyFields="Pk" InitialDataBindDepth="-1" 
        InitialExpandDepth="2" ViewStateMode="Disabled">
        <Bands>
        </Bands>
        <Columns>
            <ig:TemplateDataField Key="Delete" VisibleIndex="0" Width="16">
                <ItemTemplate>
                    <asp:ImageButton ID="btnDelete" runat="server" CommandArgument='<%# Eval("Pk") %>'
                        AlternateText="Delete" ImageUrl="~/delete.gif"
                        CausesValidation="False" OnClientClick="DeleteRow(); return false;" />
                </ItemTemplate>
            </ig:TemplateDataField>
            <ig:TemplateDataField Key="Name" VisibleIndex="1">
                <ItemTemplate>
                    <asp:Literal ID="Literal1" runat="server" Text='<%# DataBinder.Eval(((Infragistics.Web.UI.TemplateContainer)Container).DataItem, "Name") %>'></asp:Literal>
                </ItemTemplate>
                <Header Text="name" />
            </ig:TemplateDataField>
        </Columns>

            var selectedRows = grid.get_gridView().get_behaviors().get_selection().get_selectedRows();
