推荐答案

我已经找到了此解决方案，..
无需从代码后面分配任何值.只需从设计页面和目标控件将其处理到某个虚拟按钮，然后填充网格按钮功能.
您只显示模式弹出窗口.
它会解决这个问题..
如果您要代码..请回复..我会用代码解释

i have found this solution,,.
no need of assigning any value from code behind.u just handle it from design page and target control to some dummy button, then u fill grid button function.
u just show the modal popup.
it will solve this problem..
if u want code..please respond..i ll explain with code
