I recommend to use the GridPanel's BeforeEdit to allow/disallow editing.
Please see the BeforeEdit listener, the CustomConfig section and the Toggle button in the following example.
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" },
new object[] { "test2" },
new object[] { "test3" }
};
store.DataBind();
}
}
</script>
