我认为你需要这样的东西：

我只是将foreach更改为for循环并完成...

 如果 e.CommandName =   Del 然后 
 
  Dim  dt  As  DataTable =  TryCast （ViewState（ 添加），DataTable）
 
 对于 i  As  整数 =  0    dt.Rows.Count  -   1  
 如果（e.CommandArgument = dt.Rows（i ）（  cust_id）。ToString）然后 
 dt.Rows.Remove（dt.Rows（i））
  End   If  
 下一步 
 gvSavedetails.DataSource = dt 
 gvSavedetails.DataBind（）
 ViewState（ 添加）= dt 
 结束 如果

解决方案

I think you need something like this one:

ASP.Net GridView - Delete Row with Confirmation[^]

i just change foreach to for loop and its done...

If e.CommandName = "Del" Then

    Dim dt As DataTable = TryCast(ViewState("add"), DataTable)

    For i As Integer = 0 To dt.Rows.Count - 1
        If (e.CommandArgument = dt.Rows(i)("cust_id").ToString) Then
            dt.Rows.Remove(dt.Rows(i))
        End If
    Next
    gvSavedetails.DataSource = dt
    gvSavedetails.DataBind()
    ViewState("add") = dt
End If
