Syncfusion and AjaxControlToolkit ScriptManager Error

Question

I'm developing a web site using AjaxControlToolkit. To do so, i've to use ToolkitScriptManager that comes with it. It uses some different version of MicrosoftAjax.js.

Now i'm trying to use a grid from Syncfusion Essencial Tools, but it doesn't work with the ToolkitScriptManager. The syncfusion lib works with the standard Microsoft's ScriptManager and also comes with a SfScriptManager but, if i use any of them, the AjaxControlToolkit stop to work...

I can't find a workaround for this. I think that there are 3 ways to do this:

1. Use the ToolkitScriptManager and add references manually to all scripts on Syncfusion;
2. Or use the SfScriptManager and add references manually to all scripts on AjaxControlToolkit;
3. Or use the standard ScriptManager and add references manually to all scripts on AjaxControlToolkit and Syncfusion.

The problem is that i don't know exactly which scripts to add the references, neither where can I find all of them.
