推荐答案
您在哪里称"SetPreviousData"?
同样，"SetPreviousData"没有将新行添加到dataTable的代码.
ViewSTate ["GVTable"]和ViewState ["CurrentTable"]之间有什么关联?
调试代码，重点放在将DataTable置于视图状态和为网格设置dataSource的区域.
Where are you calling "SetPreviousData"?
also "SetPreviousData" does not have the code to add the new row to dataTable.
And what is the correlation between ViewSTate["GVTable"] and ViewState["CurrentTable"]?
Debug the code giving special emphasis on regions where you are putting DataTable to viewstate and where you are setting dataSource for the grid.
