推荐答案

在查看页面时，如果当前用户是管理员或用户，则必须具有该信息.根据此信息，您将设置控件的可见性.

使用grid的RowDataBound 方法设置可见性.

While viewing the page, you must be having the information if the current user is an admin or user. Based on this information, you will set the visibility of the control.

Use grid''s RowDataBound method to set the visiblity.

Protected Sub GridView_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
        Dim rtype As DataControlRowType = e.Row.RowType
        If ((rtype = DataControlRowType.DataRow)  _
                    AndAlso ((rtype <> DataControlRowType.Footer)  _
                    AndAlso ((rtype <> DataControlRowType.Separator)  _
                    AndAlso ((rtype <> DataControlRowType.Header)  _
                    AndAlso (rtype <> DataControlRowType.Pager))))) Then
            ' Get the delete button 
            ' Use Role
            ' Disable if not Admin
            If (currentRole <> "Admin") Then
                Dim btn As Button = CType(e.Row.FindControl("DeleteButton1"),Button)
                btn.Enabled = false
            End If
        End If
    End Sub

试试吧！
