 ASP.NET runtime error: The base class includes the field 'SFScriptManager1', but its type (Syncfusion.Web.UI.WebControls.Shared.SFScriptManager) is not compatible with the type of control (Syncfusion.Web.UI.WebControls.Shared.SFScriptManager).

Im new to syncfusion and im working with the ASP.Net 4.0 on the trial period version
my company is in evaluation of the components I m getting the above error on very first page
I think we have to rethink about syncfusion

Hi Vishalshukla,


Thanks for contacting Syncfusion forums.


From the error details provided by you, we suspect that there were conflicts between Syncfusion assemblies and .NET framework version. please refer Syncfusion assemblies v10.404.0.71 for .NET FrameWork 4 and v10.403.0.71 for .NET FrameWork 3.5. Also, the following assemblies should be referred to work with Tools controls,







We have also prepared a simple sample which can be downloaded from the following link,


Kindly try the sample.

I am having the same issues. Downloaded your example, same problem. Anytime I add any control I get the same error. Tried 4.0, 4.5, and 4.5.1 assemblies that I downloaded yesterday. Followed your getting started guide (You really should make that easier to find... seriously)

I have spent the whole day just trying to add a simple control to get started. Very disappointing to say the least. Only 28 days left in the evaluation. You should make your evals 60 or 90 days because it seems it will take a week to even get it started.

Any suggstions to get this going?

Hi Bean,


Thank you for contacting Syncfusion support.


As per the provided details the error reported may also arise if you have added AJAX Extension assembly references that mismatch with the referred assembly or if the version specified in the webconfig file varies. Please refer the solutions provided in the below general forums:




Please let us know if you require further assistance.
