我有一个有两个gridview的页面;一个在模态弹出窗口（grdEmpName）内，另一个在页面中（gvUser）。现在，当用户选择搜索按钮时，将弹出模态弹出扩展器，然后搜索员工。当用户选择某人时，所选数据应显示在另一个gridview（gvUser）中的文本框中。
一切都在模态弹出扩展器gridview（grdEmpName）中进行选择，但是当我选择没有数据传递给其他gridview时。 （gvUser）。我需要在文本框中显示所选数据。

现在，这是我的selectedEmployee代码（单选按钮）
Public Sub selectedEmployee(ByVal sender As Object, ByVal e As System.EventArgs)
Dim lnBTNDone As RadioButton = DirectCast(sender, RadioButton)
Dim row As GridViewRow = DirectCast(lnBTNDone.NamingContainer, GridViewRow)
Dim RowIndex As Integer = gvUser.EditIndex
Dim dt As New DataTable
dt = TryCast(Session("dbCache_User"), DataView).Table.Copy
dt.AcceptChanges()
Dim dv As New DataView(dt, "", "USR_IDNTY", DataViewRowState.OriginalRows)
Dim s As String = TryCast(gvUser.Rows(RowIndex).FindControl("lblUSR_IDNTY"), Label).Text
Dim idx As Integer = dv.Find(s)
If idx = -1 Then
Console.WriteLine("Not Found")
Else
dv(idx)("USR_ID") = row.Cells(1).Text
dv(idx)("NAME") = row.Cells(2).Text
dv(idx)("EMAIL") = row.Cells(3).Text
End If
gvUser.DataSource = dv
gvUser.DataBind()
Me.mdlEmpListProcess.Hide()
End Sub
我正在调试程序以检查值是否正在通过，然后当我传递给NAME和Email时，我遇到了这个错误
system.data.dataexception未被用户代码处理。传递值时无法设置NAME。
dv(idx)("NAME") = row.Cells(2).Text
我做错了什么？
答案
这对Google来说几乎是不可能的，但是尝试将NAME列重命名为其他内容。网格视图中存在一个名为NAME的列存在问题。
