// in your aspx page add something like this to your gridview , where the cell is, again change as it applies to you.

               </asp:TemplateField>

您可以在DataGrid_EditCommand中控制验证，也可以在单元格上进行客户端验证.如果仅使用gridview显示数据，那么为什么在填写表单后不更新数据库中的值，然后刷新gridview.您是说不想更新数据库，而只是将值从文本框传输到gridview中的单元格吗?那么您为什么不在文本框的文本更改事件中执行此操作.标准解决方案通常是***的.

You can control the validation in DataGrid_EditCommand or else put client side validation on the cells. If you are only using the gridview to display data, then why don''t you update the values in the database after your form is filled out and then refresh the gridview. Are you saying you don''t want to update the database and just transfer the value from the textbox to a cell in the gridview? then why don''t you do that in the text changed event of the textbox. standard solutions are usually the best.
