TelerikUI_RadGrid_Filter 自定义方法

要设置 EnableLinqExpressions="false"，搞了3,4个小时没反应，就是没有设置这个

Protected Sub btnSearch_Click(sender As Object, e As EventArgs)
        RadGrid1.MasterTableView.FilterExpression = "([" + "UserName" + "] ='" + "xiaoming" + "')"
        RadGrid1.MasterTableView.Rebind()
    End Sub
