I have read a lot of friends who have not yet created pages with multiple tabs. I have summarized the usage here. It's easy to understand.
1. Download The ajaxcontroltookit package and place it in the bin directory to refresh the solution.
2. Page Introduction (. aspx)CopyCodeThe Code is as follows: <% @ register Assembly = "ajaxcontroltoolkit" namespace = "ajaxcontroltoolkit" tagprefix = "asp" %>
3. Control call (. aspx)Copy codeThe Code is as follows: <asp: tabcontainer id = "TC1" runat = "server" activetabindex = "0" width = "100%">
<Asp: tabpanel id = "TP1" runat = "server" headertext = "Tab 1">
<Contenttemplate> Add Page code here </contenttemplate>
</ASP: tabpanel>
<Asp: tabpanel id = "TP2" runat = "server" headertext = "Tab 2">
<Contenttemplate> Add Page code here </contenttemplate>
</ASP: tabpanel>
</ASP: tabcontainer>
Activetabindex is the currently activated tab index, starting from 0.
