Hi,
Welcome to Ext.NET!
You can handle a GridPanel AfterRender event setting up a listener.
http://docs.sencha.com/ext-js/3-4/#!/api/Ext.grid.EditorGridPanel-event-afteredit
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)
{
Store store = this.GridPanel1.GetStore();
store.DataSource = new object[]
{
new object[] { "test1", "test2", "test3" },
new object[] { "test4", "test5", "test6" },
new object[] { "test7", "test8", "test9" },
};
store.DataBind();
}
}
</script>
