[CLOSED] Sorry~ one more question.

After each call to the server to get the grid content I get a second call performed automaticaly by the Store itself calling the "onRefresh" event.
this causes every request go twice to the server.

first request -> no action
Second request -> action

but next tree node click -> previous data (first request) action.

protected void Store1_Refresh(object sender, StoreRefreshDataEventArgs e)
    {
        if (X.IsAjaxRequest)
        {
            string id = e.Parameters["DrFileName"];

            if (id != "" || id != null)
            {
                this.LinqDataSource1.WhereParameters["DrFileName"].DefaultValue = id ?? "-1";
                this.Store1.DataBind();
                X.Msg.Notify("CallBack", "NODE: " + id).Show();
            }
            else
            {
                this.LinqDataSource1.WhereParameters["DrFileName"].DefaultValue = "-1";
                this.Store1.DataBind();
                X.Msg.Notify("CallBack", "NODE: " + id).Show();
            }
        }
    }


    protected void LinqDataSource1_Selecting(object sender, LinqDataSourceSelectEventArgs e) 
    {
        e.WhereParameters["DrFileName"] = this.HiddenDrFileName.Value ?? "-1"; 
    }

Hi,

The thread is related to:
http://forums.ext.net/showthread.php?18195

Regarding the question.

Not sure that I understand the problem well. Though please try to configure the Store with PageProxy.

Example

<ext:Store runat="server">
    <Proxy>
        <ext:PageProxy />
    </Proxy>
</ext:Store>
