[Solved] two grid conflict?

[Andrew]

I put two grid in a pop up edit template, but when the window pop up only the first grid trying to send request to action,why?

views: AAA

@(Html.Telerik().Grid(AAA).Name("Grid1")
    .DataKeys(dataKeys => dataKeys.Add(c => c.id))
    .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.Image).ImageHtmlAttributes(new { style = "margin-left:0" }))
    .DataBinding(dataBinding =>
    {
        dataBinding.Server().Select("Index", "AAA");
        dataBinding.Ajax()
            .Select("Select", "AAA")
            .Insert("Insert", "AAA")
            .Update("Update", "AAA")
            .Delete("Delete", "AAA");
    })
    .Columns(columns =>
    {
    ......
    })
    .Editable(editing => editing.Mode(GridEditMode.PopUp))
    .Scrollable(scroll => scroll.Enabled(true).Height(300))
    .Sortable(sortable => sortable.Enabled(false))
    .Pageable()
    .Filterable()
    .Footer(true)
)

views:custom edit template for AAA

@model Models.AAA

@{ Html.Telerik().TabStrip()
    .Name("TabStrip")
    .Items(tabstrip =>
    {
        tabstrip.Add()
        .Text("item1")
        .Content(
            @Html.Telerik().Grid(Model.BBB).Name("Grid2")
            .DataBinding(dataBinding =>
            {
                dataBinding.Ajax()
                    .Select("BBB", "Controller")
            })
            .Columns(columns =>
            {
            ......
            })
            .ToHtmlString()
        );

        tabstrip.Add()
        .Text("item2")
        .Content(
            @Html.Telerik().Grid(Model.CCC).Name("Grid3")
            .DataBinding(dataBinding =>
            {
                dataBinding.Ajax()
                    .Select("CCC", "Controller")
            })
            .Columns(columns =>
            {
            ......
            })
            .ToHtmlString()
        );
    }
    ).SelectedIndex(0).Render();

}

when I click the edit button in the first view, the second view popup, but only the Grid2 send request to the action,why? BTW, when I click insert button on the custom edit template for AAA, there is no window pop up and the page refreshed to a new location, if i just place one grid on the custom edit template for AAA,I can see the grid send request to the action, but still can not pop up window when I click insert button on the grid.
