Drag file in sharepoint

[P]

Hello,
I am using the RadUploadDropPanel and bound it to RadUpload to upload files on the server. This is part of silverlight application. 

If i use classic C# web application to host the silverlight app, the drag works fine.

But when i add the silverlight web part in sharepoint 2010, i am no longer able to drag'n drop file. Instead of drop the browser actually opens the file. Also, i have added AllowDrop = true for both the drag panel as well as raduplod controls.

Any help would be greatly appreciated.

thanks,

Hi P,

We are not aware of such issues with the RadUpload and RadUploadDropPanel controls in Windows. I attached a sample project that works as expected on our side. However, please keep in mind that this solution is testes in Win2008R2 server and there are known limitations to dropping files in the RadUpload controls under Mac and Safari.

Best wishes,

Tina,
After my reply i suspected that i would be how we are adding web part to the sharepoint, and i was right. 

If you add the XAP as silverlight webpart, it doesn't work.

If you add it as a custom webpart, it works fine. 

Since, we are using Client Object Model, we have to use Silverlight WebPart in SharePoint. Can you help to get this working with silverlight webpart as well.

thanks,

Hi P,

This issue is caused by the default Windoless mode of the SL WebPart. Basically when you add the XAP as silverlight webpart by default the SL plug-in is in Windowless mode:

<object id="SilverlightObjectTag_WebPartctl00_m_g_7e5626f6_2a6f_4bfb_bbdb_f9bcaae030f0" data="data:application/x-silverlight-2," type="application/x-silverlight-2" style="display:block" height="700px" width="100%" class="ms-dlgDisable">
    <param name="source" value="/XAPs1/383164_UploadExample.xap"/>
    <param name="onerror" value="_spOnSilverlightError_WebPartctl00_m_g_7e5626f6_2a6f_4bfb_bbdb_f9bcaae030f0" />
    <param name="background" value="white" />
    <param name="initParams" value="MS.SP.url=http%3A%2F%2Flocalhost,MS.SP.formDigest=0xBEF354F52076E9CC587E547C0BD878210F1FE50E0C378B2F9B941E13CAD0C5ED9932E9EC32D2CBC8BBB5D88499CACFCE1A5FB3CF7A6571736B456B6003D32CA8%2C31%20Aug%202011%2011%3A52%3A14%20%2D0000,MS.SP.formDigestTimeoutSeconds=1800,%3Cproperty%20name=%22WindowlessMode%22%20type%3D%22bool%22%3Efalse%3C%2Fproperty%3E" />
    <param name="windowless" value="true" />
    <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration: none;">
        <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
    </a>
</object>

However, when in windowless mode the drag/drop functionality doesn't work so you need to edit the WebPart definition to set the windowless mode to false (read more).
