How Do I: Use the ASP.NET AJAX Tabs Control?

This video demonstrates the basics of the Tabs control from the ASP.NET AJAX Control Toolkit, with which you can create a set of tabs to organize content on a Web page. The selected tab is maintained across post backs, making the Tabs control ideal for form-based administration pages.

i want to know the dynamic creation of tabs on some events like button clicked or on selectedindexchanged of dropdownlist...

and the number of tabs created should be based on the item selected by dropdowm list..

JoeStagner : On March 14, 2008 11:14 AM said:

There is good news and bad news.

The good news is that tabs are easy to add.

TabPanel[] newpanels = new TabPanel[NumNewTabs];

for ( iCnt = 0; iCnt < 3; iCnt++)

{

newpanels[iCnt] = new TabPanel();

newpanels[iCnt].HeaderText = String.Concat("New Panel" + iCnt);

TabContainer1.Tabs.Add(newpanels[iCnt]);

}

The bad news is that if your AJAX application si doing page postbacks, your added tabs don't survive a postback so you will have to keep that of what you've added and RE-created the added Tabs in the Page_Init method.

I just downloaded the Ajax Control Toolkit 3.5 for VS 2008. However, after loading the controls into my toolbox, I see the TabContainer control, but not the TabPanel control which is used in the video.

JoeStagner : On March 15, 2008 9:48 AM said:

TabContainer is the root control.

Panels are like templates inside the container.

Hi Joe,

I am trying to start using the AjaxControlToolkit. I followed all the

instructions on the following page:

ajax.asp.net/.../Setup.aspx

The only thing I did differently is I did not create my website from the

"ASP.NET AJAX Web Site" template, because my site already exists, and I

don't want to recreate the whole thing. I can see all the "AJAX Extensions"

and "AJAX Control Toolkit" controls listed in Visual Studio .NET 2005's

Toolbox.

The control i am making use of is tab control.

I have added a script manager and a tab control. Then a tab panel inside the tab control. Added contenttemplate to the tab panel.

when i run the application, nothing gets displayed.

please find my code.

NettaA : On March 25, 2008 7:47 AM said:

you have to use css, like here:

www.asp.net/.../Tabs.aspx

(i'm working on it right now...)

NettaA : On March 25, 2008 7:58 AM said:

Hi Joe, I have a question..

I want my tabs-headers to have rounded-corners + shadows.

I almost got everything OK, using CSS, but it is still not 100%.

So I thought maby i should put tables in the HeaderTemplates, this way:

<tr>

</td>

bla bla

</td>

</td>

</tr>

</table>

</div>

</HeaderTemplate>

my question is: can i use different HeaderTemplate for active and non-active tab ?

Thanks

Chris Rivard : On March 25, 2008 9:46 AM said:

Is there a way to move the tabs from the top to the bottom? Would this be via CSS? If so, could you provide an example. Thanks!

fizch : On March 31, 2008 11:15 AM said:

How do I get the tab panel to postback on a client click event? The tab container has the active tab changed event, but that fires after the tab has changed, and the content that was on the previous tab is out of scope. The client clic event actually fires at the correct time.

LukeNLaura : On March 31, 2008 1:31 PM said:

Hi,

I need help on TabContainers where it appears on a modalpopup. The controls that are within the TabPanels are getting rendered on the screen but stepping through the code, the values of the controls (eg. textboxes) are null. So when I try to reference the textbox to get the value, the application returns back an null reference error.

I am new to AJAX controls and so any help will be greatly appreciated.

JoeStagner : On April 01, 2008 7:09 AM said:

Chris - relocating the tabs is not supported in this version of the control, but you could modify the source.

Fizch - You can postback with the ScriptManager (I'll post a video this week.) The fact that the orrigioal Tabs content is not visible doesn't mean that it's not still on the form and therefore posted back.)

LukeNLaura - a TabCotainer inside a Modal Dialog may not work. Feel free to email me (use the contact link on my blog at www.JoeOn.net) and I'll try to help.

Hi Joe,

I am have a tab container with 21 tab panels on my page.

To reach to the 21st panel I have to scroll the page horizontally instead of this I want to add a small button or kind of drop down list in which I can see the rest or the complete list of the tab panels.

Thanks.

pardo : On April 01, 2008 10:40 PM said:

The tabs control works great. However, I'm generating mine at runtime. When I wire up:

tabContainer1.attributes.add("OnClientActiveTabChanged", "SwitchTabs();")

My function "SwitchTabs();" doesn't execute. I'm able to fire execute the function if I create the control at design time, but this doesn't serve my needs. Any advice?

Thanks

JoeStagner : On April 03, 2008 6:20 PM said:

Guys - great that your pushing the limits. In order to do those kinds of things that the control is not designed to do you will need to customize the code. Luckilly, it's open source !

Dollarjunkie : On April 16, 2008 3:29 PM said:

I have a question. From the video tutorial I noticed you mentioned over and over that one could place any HTML and dynamic content within the content tags of the TabPanel Control and I wanted to know if the dynamic content could include, say, a repeater control or any other server side controls? I tried those a couple of time and wanted to get info from the expert if it is even possible to do such.

Hi Joe

I have two questions here

first is:I like the form of using tab control to navigate for my whole site because the user doesn't need to leave this page and every thing around (outside) tab control not going to effect if the user click each tab to display each page. The question is if those tab contain lots of memory to collect for example video files and sound and a lot more. Will it effect the loading time to open the home page which shown by default using the first tab.

second question: you metion we can use any kind of file in tab container for the tab to call that function to be display or used. Say my site have 3 tabs being used as a main menu for the site. first tab use for "home" page, second called "watch video" and use for calling this page have a silverlight video set to auto play and the third tab call log in and call third named "Login" to work.

Now what is the code to put in tab container to call the video page to work when the user click the second tab.

I don't know that make sense

Thank for reading Joe

nkellogg : On May 18, 2008 6:25 PM said:

Joe,

How do I have the TabPanel height adjust to a datalist that is bound at page_load? The panel shows the data but does not expand to incorporate the data within the panel...

<ajaxToolkit:TabPanel ID="WomensTabPanel" runat="server" HeaderText="Women's" TabIndex="0">

But nothing changed.

Any ideas ?

please help....

Freon22 : On June 25, 2008 4:10 PM said:

Hi songoshin,

I also had a hard time with changing the tab control styles. I guess that accounts for why there are so many third party tab controls out there. I found a blog that was great help. acushen.spaces.live.com/blog

So what I did was to copy the Css styles for the tab control into my own css.

Then I copyed all the gif for the tab control into my own image file. By the way if you download the source code all the picture (gif) are there just copy them to you own file.

I then renamed the .ajax__tab_xp to .ajax_tab_xp2

so it shows in my css file like so

/* xp theme */

.ajax__tab_xp2 .ajax__tab_header

{

font-family:verdana,tahoma,helvetica;

font-size:11px;

background:url(../admin/adminImages/tab-line.gif) repeat-x bottom;

}

.ajax__tab_xp2 .ajax__tab_outer

{

/*padding-right:4px;*/

background:url(../admin/adminImages/tab-right.gif) no-repeat right;

height:21px;

}

.ajax__tab_xp2 .ajax__tab_inner

{

padding-left:3px;

background:url(../admin/adminImages/tab-left.gif) no-repeat;

}

.ajax__tab_xp2 .ajax__tab_tab

{

height:13px;

padding:4px;

margin:0;

background:url(../images/tab.gif) repeat-x;

}

.ajax__tab_xp2 .ajax__tab_hover .ajax__tab_outer

{

background:url(../images/tab-hover-right.gif) no-repeat right;

}

.ajax__tab_xp2 .ajax__tab_hover .ajax__tab_inner

{

background:url(../images/tab-hover-left.gif) no-repeat;

}

.ajax__tab_xp2 .ajax__tab_hover .ajax__tab_tab

{

background:url(../images/tab-hover.gif) repeat-x;

}

.ajax__tab_xp2 .ajax__tab_active .ajax__tab_outer

{

background:url(../images/tab-active-right.gif) no-repeat right;

}

.ajax__tab_xp2 .ajax__tab_active .ajax__tab_inner

{

background:url(../images/tab-active-left.gif) no-repeat;

}

.ajax__tab_xp2 .ajax__tab_active .ajax__tab_tab

{

background:url(../images/tab-active.gif) repeat-x;

}

.ajax__tab_xp2 .ajax__tab_body

{

font-family:verdana,tahoma,helvetica;

font-size:10pt;

border:1px solid #999999;

border-top:0;

padding:8px;

background-color: Gray;

}

Now the last thing you need to do is apply the CssClass so my TabContainer looks like this.

<cc1:TabContainer ID="TabContainer1" runat="server"

Height="300px" Width="600px" ScrollBars="Vertical"

CssClass="ajax__tab_xp2" >

<cc1:TabPanel ID="TabPanel1" runat="server" HeaderText="Page 1">

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

</ContentTemplate>

</cc1:TabPanel>

<cc1:TabPanel ID="TabPanel2" runat="server" HeaderText="Page 2">

Page 2

</ContentTemplate>

</cc1:TabPanel>

<cc1:TabPanel ID="tabPanel3" runat="server" HeaderText="Page 3">

Page 3

</ContentTemplate>

</cc1:TabPanel>

</cc1:TabContainer>

You now have full control over the tab control style. Or I should say more control then you had before. LOL

jmurekezi : On July 09, 2008 8:14 AM said:

Hello,

How can you add a dynamic gridview(gv2) on let say tabpannel2 where the contents of gv2 has values passed by gv1 in Tabpannel1.

When a user selectvalue in gv1 he will be directed to the pannel2 and then gv2 be populated by values where the ID of the selectedValue matches the value in database.

Thanks

skendrot : On July 10, 2008 4:15 PM said:

punitmdoshi,

I have done the add part. But I have for deleting tabs.

On my tabs, I place a [x] button (to close) which has an onclick event that sets a bool variable (closeTab) to true;

I subscribe to the OnClientActiveTabChanged event of the TabContainer. That method is below.

function TabAreaActiveTabChanged(sender, e)

{

if(sender == null) return;

if(closeTab)

{

var tabs = sender.get_tabs();

var activeTabIndex = sender._activeTabIndex;

if((activeTabIndex >= 0) && (activeTabIndex < tabs.length))

{

//Set to false so that we do not get back in here when the tab is hidden

closeTab = false;

var tab = tabs[activeTabIndex];

tab._hide();

Array.remove(tabs, tab);

}

skendrot : On July 10, 2008 4:18 PM said:

Hmm.. no way to edit a post.

Sorry, I have NOT done the add part, but have done the delete. I have noticed a problem when you delete the second to last tab. I'm not sure if this is a bug in the toolkit, or something I am doing wrong.

Hope this helps!

The video is really great.

I am trying to create a tabbed page with three tabs on it. I added the AJAX Web form and now I am not too sure what I have to do.

and when I am trying to go to the Source page it doesn't give me the Client and Objects page .. I think the Scripting page.

Could you please let me know what exactly do I have to do.

I was wodering if I could make the tab headers in a special design i.e. put some extra space between them / add special design to a specific tab header and so on.

is it possible?

I have manually developed one in JavaScript but it's really ugly especially if there is an way to use Ajax.

here: farm4.static.flickr.com/.../2727414530_b793984afb_o.jpg iss what I developed.

What about nested tabs. Lets say I have an Admin tab, user clicks on that tab and I want to see a 2nd row of tabs and so on.

example:

cse-mjmcl.cse.bris.ac.uk/.../nested.html

dba123 : On August 13, 2008 5:37 PM said:

I have found this control to be a pain in the ass. Managing postbacks, and doing something as simple as loading a page when you click a hyperlink is something not easy.

Here are other issues and problems I came across:

1) I have a nested tab setup. The panel in both controls has a blank header because I always want those to load by default.

a) how to get those two to always load by default. I do not see a way to target a certain panel and furthermore if you click on lets say a root parent panel, how to target a sub panel if you wanted to based on the click of the first. But just for starters, I don't see a way to specify default panels on page loads.

2) I tried adding a repeater to one of my tab's controls (.ascx). I bound it using a generic list. I stepped through with the dubugger and sure enough the grid has values but nothing is rendered to the page. This is just more wierdness with this tab control in general. I should not have to think twice about something like a simple binding to a repeater, etc.

3) It seems like all tabs are being loaded at runtime. That's horrible. Only the default tab should load first and then when you cilck on a tab, that page does a partial postback or even full, I don't care but either way, if my entire site is loading everything every time you do an initial post or even postback, everytime is not good loading every page in every tab.

4) If I have a hyperlink in one of my tab's pages, I want the user to see a new tab to view whatever page they are redirected to. Like in Firefox. This seems simple enough but I bet you that you must do some extensive javascript to do this. Rather than without tabs, you just redirect in a normal asp.net application. So dealing with things such as redirection, postbacks becomes a huge burden in this control

5) Maintaining tab state. I still do not see how this is done if you can at all. If I refresh my page, somehow client-side should maintain state and not jump to your default tab again.
