Problem with $find(=<%RadControl.ClientID %>) function in web user control

[Jeppe]

Hi.

I have this problem with calling the $find function (inside a web user controL). I have a situation where a change of dirent radcontrols (specifically a combobox) will set the selected index of a multipage control and other operations. And it works fine client side. But if i want to reflect changes made on serverside (for instance after a page load) I run into problems

The following type of code works when hooking up to the OnClientSelectedIndexChanged event of a RadCombobox:

function

OnClientSelectedIndexChanged(sender, eventArgs) {

var index = sender.get_selectedIndex();

var multipage = $find("<%=RadMultiPageParameterValueKind.ClientID %>");

multipage.set_selectedIndex(index);

}

However if the same type of code is called from OnClientLoad event. The $find function returns null.

NB! In the top Hierachy there is a MasterPage with a RadScriptManager. And this code is inside a Web User Control.

Hello Jeppe,

Any JavaScript function named pageLoad() will automatically wireup as an Application.Load handler (basically, the client-side version of Page_Load). For details on the matter please refer to the following ASP.NET article.
