I was able to reproduce the problem on my side. The problem is in the RadFileExplorer
control and I have logged it in our Issue Tracking System. We will fix the issue for the next internal build and you can download it from your Telerik
account. For the time being, however, I recommend you to set a value different than "10" to the RadFileExplorer1.Grid.PageSize
property and you will not experience the problem.
Please do not hesitate to contact us if you experience any further problems.
