}`

SugFriends.ascx这是一个正在添加的用户控件Default.Master

当我点击"a.button"回发事件到服务器时？（我想向数据库插入数据，我使用了 Sql server）

怎么做？让标签成为onclick“喜欢”的事件LinkButton: Onclick()？

感谢您的帮助！我找到了解决这个问题的方法！我为每个标签 a 使用 Ajax onclick，事件发布 Ajax.aspx，在这里我可以使用数据库编写代码！

Add an onclick="(javascript:__doPostBack('','');" attribute to the <a> tag to perform a postback via Javascript. Like this:

            + "<a href=\"#\" class=\"button mycoblue\" onclick=\"(javascript:__doPostBack('','');\">Kết bạn</a>"

Response to comment:

Try creating a button on the page <asp:Button ID="btnPlaceHolder" Visible="False" runat="server" /> and then do what I said in this solution but instead use __doPostBack('<%=btnPlaceHolder.UniqueID %>', '')

From there, you can use the method block Private Sub btnPlaceHolder_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPlaceHolder.Click to run the code you want on postback.
