我遇到了“保存”链接按钮触发的问题而且不知所措。我已经包含了表单和代码隐藏的代码。我添加了一些测试来查看事件是否正在触发，但似乎并非如此。任何帮助表示赞赏。我是新手编码器，如果有明显的问题或更好的方法，请原谅我。最终目标是为给定的屏幕信息更新数据库中的条目，然后重新显示更新的信息。
再次感谢你。
UPDATE: I have included the FULL-ish CODE: (removed the sensitive info)

您的链接按钮位于formview项目模板中，如下所示，因此您将无法获得单独的控制事件（链接按钮的onclick事件）。相反，您需要处理FormView.ItemCommand并进行处理，如
<asp:FormView ID="fvdoc" runat="server"
DataSourceID="gvdb" onitemcommand="itemCommandClick">
<ItemTemplate>
.......
<asp:LinkButton runat="server" Text="Save" ID="SaveButton" CommandName="Update" .........
在代码后面处理这个像
void itemCommandClick(Object sender, FormViewCommandEventArgs e)
{
if (e.CommandName == "Update")
{
LinkButton button = e.CommandSource as LinkButton;
//Do rest of the processing
}
}

您的FormView缺少EditItemTemplate，如下所示：
<asp:FormView ID="fvdoc" runat="server" DataSourceID="gvdb" OnItemCommand="fvdoc_ItemCommand">
<ItemTemplate>
<!--... Use readonly controls like Label etc...-->
<asp:LinkButton runat="server" Text="Save" ID="EditButton" CommandName="Edit" CssClass="clear-fix btn btn-primary" />
</ItemTemplate>
<EditItemTemplate>
<!--... Use editable controls like TextBox etc...-->
<asp:LinkButton runat="server" Text="Save" ID="SaveButton" CommandName="Update" CssClass="clear-fix btn btn-primary" />
</EditItemTemplate>
</asp:FormView>
单击编辑按钮，更改为编辑模式，然后处理保存按钮以保存新值。
