I am trying to change the selected tab from a hyperlink within a TabPanel to activate another tab (TabPanel). Ideally, I would like to do this on the client side using javascript. Can this be done and if so how?
I am using the official release version of the Ajax Control Tookit.
Thanks in advance for any help or suggestions!

Hi,
you can use this javascript method and call the method from a hyperlink control:
function SetActiveTab(tabControl, tabNumber)
{
var ctrl = $find(tabControl);
ctrl.set_activeTab(ctrl.get_tabs()[tabNumber]);
}
I have an example for you:
<%@. Page Language="C#" AutoEventWireup="true" CodeFile="Evaluator.aspx.cs" Inherits="Evaluator" %><%@. Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" > <head id="Head1" runat="server"> <title>Tab Control </title> <script> function SetActiveTab(tabControl, tabNumber) { var ctrl = $find(tabControl); ctrl.set_activeTab(ctrl.get_tabs()[tabNumber]); } </script> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <input type="Button" id="tabChange" value="Set Tab" onclick="SetActiveTab('<%=Tabs.ClientID%>', 1)" /> <br /> <cc1:TabContainer ID="Tabs" runat="server"> <cc1:TabPanel runat="server" ID="tab1" HeaderText="Tab 1"> <ContentTemplate> Test Tab 1 </ContentTemplate> </cc1:TabPanel> <cc1:TabPanel runat="server" ID="tab2" HeaderText="Tab 2"> <ContentTemplate> Test Panel 2 </ContentTemplate> </cc1:TabPanel> <cc1:TabPanel runat="server" ID="tab3" HeaderText="Tab 3"> <ContentTemplate> Test Panel 3 </ContentTemplate> </cc1:TabPanel> </cc1:TabContainer> </form> </body></html> RegardsMarc Andre
Thank you very much! That works perfectly.

What about server side changing?
Anyone?
also interested in server-side - thanks.
right infront of me - "tabs.ActiveTabIndex = 0" where tabs is the tabcontainerid and 0 = tabid.
I am trying to programatically change the Active Tab to Tab B, after doing a partial page postback using an UpdatePanel in Tab A. It doesn't work. If I do a full page postback it does work. Can you switch tabs programatically after a partial page postback?

I'm having the same issue right now. I haven't tried performing a "full postback" yet, but I can't seem to get the tabs to change.
This is what I've done to resolve this issue.
I have a TabContainer that has about 4-5 tabs depending on the tabs required by the user. Each tab has an update panel within it to prevent full postbacks. What I did was housed the entire TabContainer in a "parent" UpdatePanel. Once I have set it to change the active tab via TabContainer.ActiveTabIndex = 0,1,2 etc I tell the parent UpdatePanel to update. See code example below
TabContainer.ActivetabIndex = 1
ParentUpdatePanel.Update()
Voila!
Hi!
I've same but little different problem. When user clicks on a non_active tab, I want to keep active tab as active if some criteria doesn't meet. For example, I've 2 tabs in tab container. Suppose Tag[0] is active tab right now. When user clicks on Tag[1], I call a javascript method, that I've set in the OnClientClick property of Tag[1]. The JavaScript method is as under
function checkCriteria()
{
var stopTabChange = true;
if (stopTabChange)
{
var ctrl = $find('<%=myTabs.ClientID%>');
ctrl.set_activeTab(ctrl.get_tabs()[0]);
}
}
The above method is called when user clicks on Tag[1]. I assume that due to above method, Tag[1] will not become active and Tag[0] will remain active. But instead of above method, Tag[1] still becomes active. Can you help me that please?

Hi!
Thanks everybody, I figured it out how to do that. I called above method in OnClientActiveTabChanged event of TabContainer and it worked.

I'm sorry for not understanding this but I am very new to AJAX controls and need a little help with VB.Net code behind to do this:
"right infront of me - "tabs.ActiveTabIndex = 0" where tabs is the tabcontainerid and 0 = tabid."
can anyone please point me to an example in VB.Net?
I have 3 tabs in my TabContainer and on certain criteria need to change the visible Tabpanel using the code-behind. Any help would be greatly appreciated. TIA,
Coleen,
Let's say on a button click you want to change the active tab panel. In that case, under the buttons onClick event you would write some code that would look like below:
TabContainerName.ActiveTabIndex = 0 ' or any number from 0, 1, 2 - because in your example you only have three tabs.
Does that make sense?
Yes, thank you very much!
Actually I tried to setActiveTabIndex in event handler on Click edit commend in GridView as aserver sidesolution and is not working, at least in my case.
