I'm using a TabContainer. Is there a way to refresh/rebind everything once a tab is selected? Currently, it does not matter if the tab as changed or not, nothing in the selected tab is updated.

First of all tell me are u using Ajax toolkit controls?

If you are using a Ajax toolkit's tabcontainer there is property of tabpanel as onclick and onclientclick events

onclick  makes a post back . and where as onclientclick is to call a javascript function on client side...

You should go in source code of aspx file and check the propertieds if it!

I see. Yes, I'm using Ajax Control Toolkit tabcontainer control.

use asp.net menus control if you want to postback the tabs instead of ajax tabs.

 If you want to rebind the data control inside tabpanel, you can define OnActiveTabChanged event to rebind the datasource of the corresponding control.

Thanks! I'll give that a try.

make autopostback properties of tab container is true and 

write code in the event ActiveTabChanged

sample code:------

protected void ajaxtabDRCamp_ActiveTabChanged(object sender, EventArgs e)

 {

       switch (ajaxtabDRCamp.ActiveTabIndex)

        {

             case 0:

                  if (ViewState["BaseHosCount"] == null)

                  {

                   Bind Data();

                     ViewState["BaseHosCount"] = "1";

                 }

                   break;

             case 1:

               if (ViewState["ScreenCount"] == null)

             {

                  Bind Data2();

                    ViewState["ScreenCount"] = "1";

                }            

             break;

        case 2:

          if (ViewState["AwareCount"] == null)

                {

                   DRAwarenessEdit();    

             }   

              break;

                       }

Rakeshkr, thank you so much for the sample code. I'll definitely give that a try.

Hi

You can use what is mentioned by "Vince" , the property OnActiveTabChanged event and attach an event handler in your client side code.In that you can either use asp.net ajax web service to perform DB operation or use javascript __doPostback() method to fire a complete page postback.

Also you can chk out my blog explaining on how you can get more hold on AjaxControlToolkit by inspecting the internals of its extender control source code.Following is the URL :-

Quick question. Why do I need a swtich...case if all I want is re-bind the data again? Can you explain the idea behind the swithc...case?

Okay, here's a dumb question.

Why can't I type in Databind() inside of the ActiveTabChanged method? I tried it and it's not working.

 Did you use any updatepanel there? If you trigger ActiveTabChanged event, it will do full postback and execute databind. If you used updatepanel, you had better use it to wrap the entire tabcontainer.

That's a good idea but as I said in my previous post, DataBind() inside of the ActiveTabChanged method does not work.

Was it able to do postback? Could you please post your code behind and html code?

Hi,

its depends upon your no. of tab using in your application

if no. of tab is more than better to use switch 

it make your application faster than if else laddder statement.
