Gridview不保持回发状态 [英] Gridview is not maintaining state on postback

问题描述

我遇到的情况是我正在使用2个gridview，每个都有一个复选框来选择该行，现在在第一个gridview上选中一个复选框时，该行将添加到第二个gridview上.

我正在通过选择第一个gridview的复选框和.cs类上的__dopostback来执行此操作，我正在第二个gridview上添加该行.

问题:

1)回发后在第一个gridview上未选中该复选框，gridview不会保持状态吗?

2)在第二回发时，我无法获取第二gridview的数据源.

请指教.


谢谢.

Hi,

I have a situation where I am using 2 gridviews each having checkbox to select the row, Now on the selection of a checkbox on first gridview that row gets added on 2nd gridview.

I am doing it by __dopostback on the selection of the checkbox of first gridview and on .cs class I am adding that row on 2nd gridview.

Issues:

1) the check box is not checked on first gridview after postback, Does gridview not maintain a state?

2) on second post back I am not able to get the datasource of second gridview.

Please advise.


Thanks.
Divya

推荐答案

基于您所说的，我只能说检查您在哪里创建gridview ...在aspx页面中，或在代码背后创建?如果在代码后面，请在Page_Init()方法中创建它，以帮助在回发期间将其持久化.

Only thing I can say based on what you''ve said, is check where you are creating the gridview... is it in the aspx page, or created in the code-behind? If code-behind, create it in the Page_Init() method to help persist it during postbacks.
