Arithmetic Exception

[Ulrich]

Hello Telerik Team,

I am facing a rather strange problem with the telerik dropdownlist and listbox.

I am developing an application which relies on a couple of nonmanaged driver-dlls. As soon as I load one particular dll, after that I cannot instanianate ANY telerik dropdownlist or listbox. As soon as the controls ctor is called, an arithmeticexception is thrown. The call stack is as follows:

bei Telerik.WinControls.UI.RadScrollBarElement.get_ThumbLengthProportion()
bei Telerik.WinControls.UI.RadScrollBarElement.SetupThumb(Int32 newValue, Boolean thumbLocationOnly)
bei Telerik.WinControls.UI.RadScrollBarElement.set_Maximum(Int32 value)

Do you have any idea how I could work around this problem?

Hello Ulrich,

Can you please provide some more information, some code snippets, a small sample, or anything from which i can start working on a solution for your problem?

Best regards,

Hello Emanuel,

I will try to make a package where you can debug the problem.

I am well aware that the problem might stem from a third party component and might not be directly a bug from telerik, but all standard user controls work. That's why I thought I post since the telerik team has a deeper knowledge about what happens inside their controls than I have.

I will try to provide you with a package tomorrow, I just have to make sure that the dll in question loads without the needed hardware attached to the computer, so you can take a look at the problem.

best regards

Hello Ulrich, 

Thank you for writing.

The provided information is not enough for us to determine the reason for the exception. This is why I would like to kindly ask you to prepare a sample project where this exception is thrown. Please note that you should open a ticket in order to attach the project. This will allow me to investigate your case locally and provide you with further assistance.

I am looking forward to your reply.

Greetings,
Stefan
the Telerik team
