How do Telerik controls programmatically register their scripts with the ScriptManager? I have created a custom control and the only way I can get the scripts to register is by explicitly referencing the script in the page's markup.

<asp:ScriptManager runat="server" ID="ScriptManager1">
<Scripts>
<asp:ScriptReference Assembly="Core.WebBase" Name="Core.Resources.Scripts.ScriptTest.js" />
</Scripts>
</asp:ScriptManager>

But how to do this programmatically? I cannot expect my users to know to do this for every page they use the control on. I've used the ClientScript to do this like so: Page.ClientScript.RegisterClientScriptResource(typeof(ScriptTest), "Atl.Core.Resources.Scripts.ScriptTest.js"); but this does not work with asynchronous postbacks. Whats the trick? :)

Well, I figured it out. It is as simple as using

ScriptManager.RegisterClientScriptResource(this, typeof(ScriptTest), "Core.Resources.Scripts.ScriptTest.js");

instead of

Page.ClientScript.RegisterClientScriptResource(typeof(ScriptTest), "Core.Resources.Scripts.ScriptTest.js");

I was confused because I didn't realize RegisterClientScriptResource is a static method on the ScriptManager class. I thought I had to get a reference of the ScriptManager from the Page.

Hi Jonathan,

I am glad to see that you have managed to find the solution on your own - yes, we are also registering our scripts as ClientScriptResources of the ScriptManager.

You can also find useful the following MSDN article explaining the usage of the RegisterClientScriptResource method:
