Dotnetbar中的一个问题？

t6786780 2010-11-15 05:57:51

最近在研究Dotnetbar，可是有一个问题让人很郁闷。
直接拖拽一个DataGridViewX到窗体中，禁用DataGridViewX自带的添加，删除，修改功能，后台写入下以下代码：
在最后一行中ButtonX的值总是不能显示，如果把
DataGridViewButtonXColumn column3 = new DataGridViewButtonXColumn(); 替换成
DataGridViewButtonColumn column3 = new DataGridViewButtonColumn(); 就能显示。我真郁闷的要死。有谁用过这个，帮下忙了。我现在的目的是不要添加，删除，修改的功能，只需要让这个DataGridViewX展示数据就够了。让他把最后一行的那个ButtonX的值显示上去！谢谢了。

            DataGridViewButtonXColumn column3 = new DataGridViewButtonXColumn();

            DataGridViewTextBoxColumn column4 = new DataGridViewTextBoxColumn();

            column1.Width = 100;

            column1.DataPropertyName = "bh";

            column1.HeaderText = "编号";

            column2.Width = 150;

            column2.DataPropertyName = "zxshk";
