Hi,

Yes you can use Javascript functions inside widgets. But there is a trick.

We create your widget after an async postback and a dashboard may have multiple instances of your widget. So to prevent dublication, I recommed you to put all your javascript functions inside a seperate js file and reference this file from the page in which DashboardSurface control is located. Then you can use your functions.

If you just need to set a hidden variable you can also use inline javascript like

<button onclick="javascript:alert('xxx') > ...

-tansu

if your control is server control you can call your control shown below.

<button onclick="javascript:alert(document.getElementById('<%= YourControl.ClientID%>').value) >

Regards.
