Silverlight webpart drag and drop not working

I wrote a new Silverlight webpart and was using Drag and Drop functionality. But as soon as I use this inside share point, drag and drop stopped working.

As I was using OOTB Silverlight webpart to load the XAP. Silverlight webpart set Windowless property to TRUE by default and this is what caused the issue.

So I exported the exisiting ootb webpart definition DWP file on desktop, edited the Windowless property to False and uploaded the webpart again and it works.

Also you can copy the below XML into a DWP file and upload it to sharepoint.


Code ( Silverlight_WindowLess_Webpart.dwp ):

<webPart xmlns="">
<type name="Microsoft.SharePoint.WebPartPages.SilverlightWebPart, Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />

Edit the Webpart > In Advanced Section > Under export section > make sure Export All is selected > once you save that setting.. under Edit the webpart you will see Export option now....
