Hello,

I'm trying to find a simple solution of drag & drop with C# and AJAX to move buttons in a grid. I've found this solution that is using WebPart: http://waitink.blogspot.com/2008/06/ajax-web-parts-part-1-drag-and-drop.html This solution seem's to be pretyty nice but I'm getting an error when I'm trying to execute my code because I do not have any database and I don't want to install a databse for this application.

Question is: Is it possible to use WebPartManager without database ? How ?

Thanks!

If you want to enable the personalization-related features of WebParts, you need to use some sort of personalization provider to store the data.  You can implement a custom personalization provider to store the data however you'd like.

Im not sure about it. but If you need Personalization for WebParts then Database is a necessity  because it is where the personalized data will be stored.. But if you don't need personalization then Just set the attribute Personalization-Enabled to FALSE in the WebPartManager like below

<asp:WebPartManager runat="server" id="WebPartManager1" personalization-enabled="false" /> 

Refer below for more informations

If you write a custom personalization provider, you can store and retrieve the data however you'd like (database, web service, xml file, etc.).  You could even store it in memory, though you'd lose the data when the application shut down.

For most practical purposes you either want personalization disabled, or else you want to store it in some persistent way.
