推荐答案

编辑后点击更新按钮阅读那时的所有文本框值。

After editing when you click on update button read all the textbox values at that time.

HI，



您可以通过将单元格值分配到隐藏字段来完成此操作将数据绑定到网格。当您尝试访问编辑按钮上的值时，您可以轻松地从隐藏字段中获取值。试试这样。



如何在网格视图中编辑和更新行值？

谢谢

You can do this by assigning the cell values into hidden fields while binding the data to the grid. And when you are trying to access the value on the edit button click you can get the values from the hidden fields easily. Try like this.
