“只能在Render（）;”中调用RegisterForEventValidation。 [英] "RegisterForEventValidation can only be called during Render();"

问题描述

我在将数据从gridview传输到excel时遇到此错误，任何人都可以向我建议解决方案RegisterForEventValidation只能在Render（）期间调用;



我有一个解决方案，我应该做EnableEventValidation = false并在我的代码中生成事件VerifyRenderingInServerForm（控制控件）...我也这样做了..

现在我没有收到任何错误...但excel文件没有生成..帮助......

解决方案

我曾经在这里得到了一些帮助：

看看这对你有帮助:)期待你的评论。

用于生成excel文件的按钮..;将该按钮放在< asp：postbacktrigger xmlns：asp =＃unknown> <触发器>的标签tab ...

如果ur网格正在进行分页，那么在将数据导出到excel时使用Datatable而不是使用gridview因为如果你使用gridview那么它将不会生成正确的excel文件...

或你可以做到这一点..而generatin excel再次从数据库中获取数据......

Iam getting this error while transferring data from gridview to excel, can any one suggest me the solution"RegisterForEventValidation can only be called during Render();"

I got a solution that i should do EnableEventValidation=false and generate the event VerifyRenderingInServerForm(Control control) in my code...i did this too..
now i am not getting any error...but excel file is not getting generated..help...

解决方案

I had once done this with some help from here:

http://stackoverflow.com/questions/8908363/exporting-gridview-to-xls-paging-issue[^]

See if that helps you too :) Looking forward for your comments.

The button that is supposd to generate the excel file..;place that button in the <asp:postbacktrigger xmlns:asp="#unknown"> tab of the <triggers> tab...
and if ur grid is doing paging then while exporting the data into excel use the Datatable instead of using the gridview coz if u use gridview then it will not generate proper excel file...
or u can do this..while generatin excel again get the data from the DB...
