C# 如何在asp.net中将一个gridview行传输到另一个gridview行
我有两个网格视图：C# 如何在asp.net中将一个gridview行传输到另一个gridview行,c#,asp.net,gridview,C#,Asp.net,Gridview,我有两个网格视图： gvdetails和 gvTranferRows gvdetails从所选数据库绑定。这些字段是： id moduleName和 项目字段 在gvTransferRows中，字段包括： id ModuleName 项目和 BatchNo BatchNo从dropdownlist中选择 但我想将所选行从gvdetails传输到gvtranfrows 在此过程中，我通过同时单击“删除”按钮，成功地将gvdetails所选行删除并添加到gvTranferRows，反之亦然

使用临时数据表维护列表中选定的行或记录，然后使用数据表绑定辅助GridView
你会从这里得到更多的想法
请尝试DataTable.ImportRow方法：
我在许多WebForms和MVC页面上使用这种方法，效果非常好。第一个网格中的所有数据都将发送到第二个网格，但是我们如何从第二个网格检索到第一个网格中的数据呢？我尝试过同样的代码，也将数据从第二个网格传输到第一个网格，但它不起作用。你能帮助我吗out@user123欢迎来到Stack溢流我对你的问题进行了编辑，以设置列表、内联代码和图像的格式，从而使其正确呈现-请参阅编辑帮助以获取有关格式设置的更多信息。祝你好运
