    [CLOSED] How do you dynamically create and populate a copy of a store in code-behind ?

    Consider the simple store "stoUser" below that is loaded with data.

        <ext:Store ID="stoUser" runat="server" >
        <Model>
            <ext:Model ID="modUser" runat="server">
                <Fields>
                    <ext:ModelField Name="FirstName" />
                    <ext:ModelField Name="LastName" />
                </Fields>
            </ext:Model>
        </Model>
     </ext:Store>
    I need to dynamically create a copy of this store in code-behind and copy the data. This is something we were able to in Ext.Net v1. Below is the code I am trying to get to work;

                    var stoCopy = new Ext.Net.Store();
                stoCopy.ID = "stoCopy";
                stoCopy.ClientIDMode = ClientIDMode.Static;
 
                var modCopy = new Ext.Net.Model();
                modCopy.ID = "modCopy";
                modCopy.ClientIDMode = ClientIDMode.Static;
                foreach (ModelField fld in stoUser.Model[0].Fields)
                {
                    modCopy.Fields.Add(fld);
                }
 
                stoCopy.Model.Add(modCopy);
 
                stoCopy.Listeners.BeforeLoad.Handler += "App.stoCopy.data = App.stoUser.data.clone();";
 
                Controls.Add(stoCopy);

    Hi @betamax,

    Your code appears to be working to clone an instance of Store and I would load the data in a bit different way.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            var stoCopy = new Ext.Net.Store();
            stoCopy.ID = "stoCopy";
            var modCopy = new Ext.Net.Model();
            modCopy.ID = "modCopy";
            modCopy.Fields.AddRange(stoUser.Model[0].Fields);
            stoCopy.Model.Add(modCopy);

            this.Form.Controls.Add(stoCopy);
        }
    }
</script>

<!DOCTYPE html>
<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
       
        <ext:Store ID="stoUser" runat="server" >
            <Model>
                <ext:Model ID="modUser" runat="server">
                    <Fields>
                        <ext:ModelField Name="FirstName" />
                        <ext:ModelField Name="LastName" />
                    </Fields>
                </ext:Model>
            </Model>
         </ext:Store>
    </form>
</body>
</html>

    Turns out the original example I supplied works, we just had to add a delay to the call to clone.

    stoCopy.Listeners.BeforeLoad.Handler += "App.stoCopy.data = App.stoUser.data.clone().delay(10);";
    Solution found by user MDB
    Thanks, mark as closed
