Question

ASP.NET VB PostBack within an Update Panel

I’m trying to have a JS function load on this error (closes Loading overlay & pop-up w/ error should come up). When I try to display the label it works without a problem (of course it’s covered by the overlay).

Me.lblerrormsg.Visible = True 

I’ve tried 3 different approaches I’ve found for Registering a Script:

Dim errorScript = "<script>alert('WTF');</script>" '<-- not even this works

Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "errorDemoManual",
     errorScript, True)

'Tried this one with the Panel & Page itself...
ScriptManager.RegisterStartupScript(pnlPatientInfo, pnlPatientInfo.GetType(), 
     "ErrorDemo", errorScript, True)

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "errorScript",
     errorScript, True)

None have worked… Is there something I’m missing here??

The problem was I needed to be using RadScriptManager – part of Telerik UpdatePanels to get it working.

RadScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "errorDemoManual", "errorDemoManual();", True)
