I have a page with an UpdatePanel and inside the UpdatePanel there is a TabContainer. The content of each TabPanel is a different User Control. I am trying to set the focus on a specific textbox on one of the TabPanels/user controls, but cannot currently get it to work. I am wondering if anyone has been successful in doing something similar ?

Thanks,

 I eventually managed to get something working.  So, in case someone else has a similar problem, here is what I did:

- In the Page_Load of the user control I pass back the ClientID of the textbox like this : 

ScriptManager.RegisterClientScriptBlock(this, GetType(), "txtSearchBarcode", "var _txtSearchBarcode = '" + txtSearchBarcode.ClientID + "';", true);

 Then on the main page(which contains the Tab Container), I added this javascript:

        function getControl_TabClicked2(sender, e) {   
               control = $get(_txtSearchBarcode);      
       }      
       function setFocus(sender, e) {   
            try{
               control.focus();   
               }
            catch(e){
                //do nothing
                }
       }

 The Tab Container line looks like this :

<cc1:TabContainer ID="tcMain" runat="server" CssClass="ajax__tab_yuitabview-theme" OnClientActiveTabChanged="setFocus">

And finally the specific TabPanel :

<cc1:TabPanel ID="tcSearch" runat="server" HeaderText="Search" OnClientClick="getControl_TabClicked2">

 This is an amalgamation of a few different solutions I found on the net, hopefully it will help someone else.

Cheers,

Jim
