is added in the 2009.3 1208 and later versions of the controls In the an earlier versions of the controls, this method does not exist. In your case I strongly recommend you to update to the recent version of the control.
The provided information is not enough for me to determine the exact reason for the problem and I need some additional information about the issue.
- Could you please check whether the DeletePaths is correctly set in the RadFileExplorer's configuration?
- Could you please run the project in debug mode and let me know whether the DeleteFile method (in the content provider) is called when a file is deleted? Could you please do the same for the CreateDirectory method which is called when a folder is created.
- If the DeleteFile (the same as is for CreateDirectory) method is fired, then please make sure that there is not an exception throw in the method. If an exception is thrown this mean that the application (respectively the RadFileExplorer control) does not have enough permissions to complete the operation - Delete or Create a file/folder. In this case the exception message will show you what permissions are required to avoid the exception.
- A possible reason for the freezing behavior might be that the RadFileExplorer control is updated by using UpdatePanel, RadAjaxManager or RadAjaxPanel control. Please note that the RadFileExplorer control cannot be AJAXified, because it initiates asynchronous callbacks in order to load its items and when two or more nested AJAX requests are initiated then the result will be unpredictable. If this is the case, you need to move the RadFileExplorer control outside of the partially updated zone.
I am looking forward to hearing from you.
