Question

我有4个文本框，即first_name，last_name，gender和department以及一个gridview。 GridView包含编辑和删除按钮。当用户单击编辑按钮时，gridview中的值将读入文本框，用户将更新它，但是当我使用更新面板仅刷新gridview而不是整个页面时，这将不起作用。值无法从gridview读取到文本框。我只希望gridview视图不刷新整个页面。这是我的代码。

您还可以在另一个更新面板内覆盖gridview外的文本框..

<asp:UpdatePanel ID="UpdatePanel2 runat="server" >
<ContentTemplate>
    <asp:TextBox ID="TextBox_LastName" runat="server" Width="230px"></asp:TextBox>
 </ContentTemplate>
 </asp:UpdatePanel>

如何从gridview（更新面板之间包含）读取值到文本框？
