    [CLOSED] Add record server side to dynamically generated store

    Hi, I have a store that where I define the columns on the server side.
    I'd like to also be able to add records to this store.
    But the only method I see is store.AddRecord(object values).

    I'm getting the data for this record from various sources, and I know what the columns names are...how can I create a string of JSON, then convert that to an object so I can pass to this method?

    Hi,

    .AddRecord() method expects the same object which you data bind to a store.

    Here is an example.

    Example

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

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

<script runat="server">
    public List<object> MyData = new List<object> 
    { 
        new 
        { 
            test1 = "test1",
            test2 = "test2"
        },
        new 
        { 
            test1 = "test3",
            test2 = "test4"
        },
        
    };

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            this.Store1.DataSource = MyData;
            this.Store1.DataBind();
        }
    }

    protected void AddRecord(object sender, DirectEventArgs e)
    {
        object newRecord = new
        {
            test1 = "test5",
            test2 = "test6"
        };
        this.Store1.AddRecord(newRecord);
    }
</script>
