Hi everyone, here's my problem.

I have 3 web forms. WebForm1 contains a tab control "UltraWebTab1" with just 2 tabs.
First tab displays Target URL WebForm2.
Second tab displays Target URL WebForm3.

WebForm2 contains a label lblSourceLabel with a text value of '123'.
WebForm3 contains a label lblTargetLabel with a null value.

My goal it to transfer the lblSourceLabel value to lblTargetLabel upon tab change from tab1 to tab2. I'm using JavaScript, ASP.NET and Infragistics.

Here's my code, but it's not working. What am I doing wrong?

function sendValue()
{
// Get reference to UltraWebTab
var ultraTab = igtab_getTabById("UltraWebTab1");
if (ultraTab == null)
return;
//
// Get reference to 1st tab (WebForm2 )
var tab = ultraTab.Tabs[0];
// Get reference to 2nd tab (WebForm3)
var tab1 = ultraTab.Tabs[1];
//
var source = tab.findControl("lblSourceLabel ");
var target = tab1.findControl("lblTargetLabel");
target.value = source.value;
}

I'm not familiar with this tab control. In general, JavaScript on one WebForm will not be able to reference anything on a different WebForms. This is because WebForms are server constructs, not client constructs. Am I misunderstanding the scenario?
