我有一个gridview并使用会话将变量从页面传递到编辑页面。这很有效，直到你搜索一个数字。当您在gridview中搜索正确的记录时，但是当您单击编辑时，它会传递错误的记录。
Private Sub gridview1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(5).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(6).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(7).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(8).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(9).Text & "~\/~" & _
GridView1.Rows(e.NewEditIndex).Cells(10).Text & "~\/~"
Response.Redirect("WorkEdit.aspx")
End Sub

我意识到并不是所有的代码都粘贴在这里，因为它需要太多的空间。有任何想法吗？我猜这与e.NewEditIndex

您的代码看起来很好。 Session（“wr_id”）是实际代码，还是“wr_id”模拟代码？
我问的原因是因为会话值可以通过字符串或索引访问。
如果您的代码使用Session(selectedID)而selectedID是填充的object变量，则会根据selectedID是否更改您访问会话变量的方式数字或字符串
<强>更新：
查看您是否在代码中的任何其他位置绑定（例如，您的Page_Load事件）。在控件的编辑事件触发之前，您很可能会使用新数据重新绑定网格

该问题的解决方案是将页面加载包装在if，ispostback语句中。谢谢你的帮助rkw。
