Hi Nicolas,

Thanks for contacting Syncfusion support.

We are unable to reproduce the reported query at our end. In the Listbox control, if more items are added in the control then scrollbar is enabled automatically by calculating the height and width of the content. We have attached a sample in the following location to showcase the solution, so kindly check it.

If still you face difficulties, please revert back the sample based on your application to showcase the issue at our end. Also please tell us the version that you are currently using in your application. This would be helpful for us to analyze more about your problem and provide a solution at the earliest.

thanks for the quick responce. 

The problem might has to do with the datasource i'm ussing to show the items list has. On dialog create i build an array with the itmens i need to show and when dialog opens it shows the list with those items but no scroll bar... see the attachment. i will try to replicate the problem in an example as you send me...
