Gridpanel SelectedRows - dynamic usercontrol

[Nesse]

Hi Everyone,

I'm trying to get the SelectedRows form a dynamic loaded usercontrol that contains a gridpanel. Everytime i hit the count the result is 0, while i've selected several items. Can anyone help me? Is there a better way to do this? Should i create every control in codebehind instead of using a usercontrol? Here is my example:

usercontrol that contains the gridpanel

<ext:Label ID="LabelTitel" runat="server" Height="50" />
<ext:Hidden ID="HiddenVerplicht" runat="server" />
<ext:GridPanel ID="GridPanelSpecificatie" runat="server" Layout="FitLayout" Scroll="Vertical" AutoScroll="true" Flex="1">
    <Store>
        <ext:Store runat="server">
            <Model>
                <ext:Model runat="server" IDProperty="Id">
                    <Fields>
                        <ext:ModelField Name="Id" />
                        <ext:ModelField Name="Naam" />
                    </Fields>
                </ext:Model>
            </Model>
        </ext:Store>
    </Store>
    <ColumnModel>
        <Columns>
            <ext:Column runat="server" DataIndex="Naam" Flex="1" Border="false" />
        </Columns>
    </ColumnModel>
    <SelectionModel>
        <ext:CheckboxSelectionModel ID="CheckboxSelectionModel_GridPanelSpecificatie" runat="server">
            <Listeners>
                <SelectionChange Fn="GridPanelSpecificatie_SelectionChange" />
            </Listeners>
        </ext:CheckboxSelectionModel>
    </SelectionModel>
</ext:GridPanel>

                var PanelSpecificatie = new Panel();

                // toevoegen

                    var GridPanelSpecificatie = ControlUtils.FindChildControl(CtrlSpecificatie, "GridPanelSpecificatie") as GridPanel;

                    if (GridPanelSpecificatie != null)

                           // the count is always 0
                        }
                    }
                }

        }

Hi yash.kapoor,

This thread can be closed. I've created my setup in codebehind instead of using a usercontrol. Now everything works perfect:

            foreach (var Specificatie in AlleSpecificaties)
            {
                // control - gridpanel
                //var CtrlSpecificatie = this.LoadControl("~/controls/gridpanels/specificatie_gridpanel.ascx") as specificatie_gridpanel;
                //CtrlSpecificatie.ID = "CtrlSpecificatie_" + Specificatie.Id;
                //CtrlSpecificatie.Specificatie = Specificatie;

                // panel
                var PanelSpecificatie = new Panel
                {
                    ID = "PanelSpecificatie_" + Specificatie.Id,
                    BodyPadding = 10,
                    Layout = "VBoxLayout",
                    LayoutConfig = {
                        new VBoxLayoutConfig{ Pack = BoxPack.Start, Align = VBoxAlign.Stretch }
                    },
