Hello,
You can use "get_activeTabIndex" method of tabcontainer behavior to get
the
active tab index.
$find("TabContainer1").get_activeTabIndex();
In OnClientActiveTabChanged client event, you can use ASP.Net Ajax to
communicate with Web Method or Page Method to get the data from server and
update the related content via JavaScript DOM. With this approach, I think
it will be better/faster than with doing postback.
Please try the below sample.
<script runat="server" type="text/C#">
[System.Web.Services.WebMethod]
public static string GetContextMethod(int TabIndex) //This is Page
Method, you can also use Web Method for it.
{
string text = "text" + TabIndex.ToString();
return text;
}
</script>
<script type="text/javascript">
function changeActiveTab() {
var index = $find("TabContainer1").get_activeTabIndex(); //get the
current tab index
PageMethods.GetContextMethod(index, onsuccess); //call page method
via Ajax
}
function onsuccess(result) {
var newdata = result;
var index = $find("TabContainer1").get_activeTabIndex();//get the
current tab index
$find("TabContainer1").get_tabs()[index].get_element().innerHTML =
newdata;//update the related tab content
}
</script>
<body>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager runat="Server"
EnablePartialRendering="true" ID="ScriptManager1"
EnablePageMethods="true"/>
<ajaxToolkit:TabContainer runat="server" ID="TabContainer1"
OnClientActiveTabChanged="changeActiveTab"
ActiveTabIndex="0">
<ajaxToolkit:TabPanel runat="server" ID="TabPanel1"
HeaderText="TabPanel1">
<ContentTemplate>
TabPanel1
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel runat="server" ID="TabPanel2"
HeaderText="TabPanel2">
<ContentTemplate>
TabPanel2
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel runat="server" ID="TabPanel3"
HeaderText="TabPanel3">
<ContentTemplate>
TabPanel3
<asp:Label ID="Label1" runat="server"
Text="Label"></asp:Label>
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
</form>
</body>
