datagrid编辑列有关问题*

datagrid编辑列问题**************
web程序 ，datagrid 动态增加的列(列不固定)，怎么在datagrid后增加编辑列，并且点击编辑后只修改数值型的列（已知道那个列是数值型）
在grid前边增加编辑列，我能实现，但是客户要求把编辑列放grid后边

DataGrid.....vs2003的东西啊。。。。后续的都要自己手工添加了啊
你的动态增加的列是怎么增加的？
你也可以把编辑列作为一个动态增加的列啊


并且点击编辑后只修改数值型的列（已知道那个列是数值型）
在GridView里每个colume都是有个属性叫ReadOnly的，设为true就不可编辑了
