Telerik RadGrid open in popup when AllowMultiRowEdit="True"

[Manfred]

Hello experts... I need help please.

I have a RadGrid with multiple row edit... I want to open all checked Items in a popup when I click the edit button.

I thought I do it with <NestedViewTemplate> or with another RadGrid2. I have no idea about how do I solve this problem. Can you please give me feedback.

Here is my short code:

<telerik:RadGrid ID="myGrid" Skin="Silk" AutoGenerateColumns="false" AllowAutomaticUpdates="true"
OnNeedDataSource="myGrid_NeedDataSource" AllowPaging="True" PageSize="10" AllowMultiRowSelection="True" AllowMultiRowEdit="True"
ShowStatusBar="true" AllowFilteringByColumn="true" runat="server">    
        <MasterTableView DataKeyNames="Title" Name="myGridView" EnableHeaderContextMenu="true" ItemStyle-Wrap="False" CommandItemDisplay="Top" Width="100%" >
            <Columns>
            <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn" AllowFiltering="false" HeaderStyle-Width="2%" >
                      <ItemTemplate>
                        <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="ToggleRowSelection"
                          AutoPostBack="True" />
                      </ItemTemplate>
                      <HeaderTemplate>
                        <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState"
                          AutoPostBack="True" />
                      </HeaderTemplate>
             </telerik:GridTemplateColumn>   
                
            <telerik:GridBoundColumn UniqueName="Title" DataField="Title" HeaderText="Title" HeaderStyle-Width="15%" FilterControlAltText="Title" ReadOnly="true">
                <FilterTemplate>
