Hello Venkat,

Try the following approach:

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" OnNeedDataSource="RadGrid1_NeedDataSource"
    AutoGenerateEditColumn="true" OnItemCommand="RadGrid1_ItemCommand">
    <MasterTableView CommandItemDisplay="Top" />
</telerik:RadGrid>

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.EditCommandName)
        (RadGrid1.MasterTableView.GetColumn("Date") as GridBoundColumn).ReadOnly = true;
    if (e.CommandName == RadGrid.InitInsertCommandName)
        (RadGrid1.MasterTableView.GetColumn("Date") as GridBoundColumn).ReadOnly = false;
}

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
{
    (source as RadGrid).DataSource = GetData();
}

private DataTable GetData()
{
    DataTable table = new DataTable();
    table.Columns.Add("ID", typeof(int));
    table.Columns.Add("Date", typeof(string));
    table.Columns.Add("Type", typeof(string));
    for (int i = 0; i < 10; i++)
        table.Rows.Add(i, DateTime.Now.ToString(), i * DateTime.Now.Millisecond);
    return table;
}
