次のように宣言した JavaScript 関数に GridView ID を渡そうとしました。
'PrintGridView(Title,Address,Terms,GridViewName)'
ImageButton次のように、OnClientClickイベントの ASP.NET ページで使用します。
<asp:ImageButton ID="SendingDownTypePrintImageButton" runat="server" ImageUrl="~/images/printer.png" ToolTip="Print" OnClientClick="PrintGridView('university',' address','Terms','<%=SendingDownTypeGridView.ClientID%>')"/>
しかし、私はいつもエラーが発生します。この問題を解決するにはどうすればよいですか?
