Run Startup JS Code after Telerik JS Objects Exist

[Eric]

// Find the RadControl client object, if null then exit the function
sb.Append(String.Format("var co = $find(\"{0}\");", c.ClientID));
sb.Append("if (co == null) return;");

When I register this code with the Page.ClientScript.RegisterStartupScript method it attempts to execute before the Telerik Control Javascript objects are created resulting in "co" being assigned a null value.  How do I register startup Javascript code that executes AFTER the Telerik javascript objects are created.

Hi Eric,

The client-side objects of the controls are available after the MS AJAX framework has been initialized. You need to either place your code in a function named pageLoad or use the load event of Sys.Application:

Copy Code

function pageLoad()
{
}

// OR

// Attach a handler to the load event.
Sys.Application.add_load(applicationLoad);

function applicationLoad()
{
}

I hope this helps.

All the best,
