        {
           List<SubmittedNode> selectedNode= ((Ext.Net.TreeSelectionModel)(TreePanel1.GetSelectionModel())).SelectedNodes;
           if (selectedNode != null && selectedNode.Count > 0)
           {
               SubmittedNode currentNode= selectedNode[0];
               DTO grd = Lst.FirstOrDefault(g => g.Id.ToString() == currentNode.NodeID);
               if (!currentNode.Checked)
               {
               Store grdstore=GridPanel1.GetStore();
               grdstore.Insert(0, grd);
               grdstore.DataBind();
          }
     }

<ext:Store ID="store_act" runat="server" AutoSync="false">
        <Model>
          <ext:Model ID="model_act" runat="server" IDProperty="ACV_ID" Name="ACT">
              <Fields>
                  <ext:ModelField Name="ACV_ID" Type="Int"  />
                  <ext:ModelField Name="ACV_DATE" Type="Date" />
                  <ext:ModelField Name="ACV_HOURS" Type="Float"/>

              </Fields>
          </ext:Model>
        </Model>
 </ext:Store>

In Javascript

      var newrow = new ACT({ ACV_DATE: new Date(), ACV_HOURS: 15 });
      newrow.phantom = true;
      App.store_act.insert(0, newrow);

I do it in codebehind using directEvent
Is there a solution using codebehind C# Code?

Hi @AdminAISN,

Welcome to the Ext.NET forum!

I think you should remove this:

grdstore.DataBind();

It is uses a Store's DataSource which you are not setting up. So, the Store is bound with no data erasing an added record by the Insert call.

@mtsig, thank you for answering! Much appreciated.

               if (!currentNode.Checked)
               {
               Store grdstore=GridPanel1.GetStore();
               grdstore.Insert(0, grd);
               grdstore.DataBind();
          }
     }

I tried but unfortunetly it doesn't work. I was obliged to rebuild the datasource. Perhaps somebody will gie me an help.
Thx.

Hello!

Couldn't reproduce with the following sample:

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            this.Store1.DataSource = this.Data;
            this.Store1.DataBind();
        }
    }

    protected void AddRecord(object sender, DirectEventArgs e)
    {
        Store1.Insert(0,  new { company = "3m Co", price = 71.72, change = 0.02, pctChange = 0.03, lastChange = "9/1 12:00am" });
    }

    private object[] Data
    {
        get
        {
            return new object[]
