After a year of answering questions at the WebParts and Personalization forum section, I consider the following items below as “frequently asked questions”.

I decided to write this so that I can point them to this post whenever I find a question that can be found here.

3. WebParts Drag and Drop not Working on FireFox using ASP.NET 2.0

This is a very known issues on ASPNET WebParts.. Basically WebParts doesn't support the Drag and Drop feature in FF browser.. The drag and drop feature will only work if you are using Visual studio 2008 /VWD 2008 with latest version of the WebPart Futures (AJAX Control Toolkit 3.5)..

You may refer below for more information:

If you are working with ASPNET 2.0 then I have written a sample snippet at the following link below on how we are going to move the WebParts in fire-fox without the Drag and Drop Feature by using Custom Verbs.

You can also use Atlas to support the drag and drop feature in firefox in ASP.NET 2.0.

If you wan’t to hide it manually then we can use the Hidden property to Hide WebParts in the Zone. See below example:

protected void Button1_Click(object sender, EventArgs e)
{
        WebPartZone1.WebParts["WebPartID"].Hidden = true;
} 

You may also close the WebParts instead using the CloseWebPart method of WPM and add it back again via PageCatalogPart.

13. How to Add Custom Verbs to WebParts?

You can add your own verbs by extending the WebPartZone base class and override the OncreateVerb method for you to add your own verbs for all the WebParts. See the example in the link below for more info.

If you wan’t to add a custom verb to a particular webpart then you can override the WebPartVerbCollection  class as demonstrated in the link below:

14. How to work WebParts with Master Page?

Basically, WebParts Personalization are stored on a page by page basis. Web Parts personalization settings for the pages that use the Master Page are stored separately from one another, preventing you from applying a single set of Web Parts to every page on the site.

# re: ASP.NET WebPart FAQ
Requesting Gravatar...
Thanks for the information. I have one question that I hope you can answer. I have a few web parts that are conencted to a search web part. When users select a particular item, I want to retrieve different information about the item in each web part. Each web part contains a user control that performs asynchronous calls to DAL and web services, but the main page is only refreshed once all the data is gathered.

Is there a way to update each web part indivisually when it's user control is done getting the data? Visually, I'd like a "Please wait" image to appear in each web part and for each one to be rendered as soon as the data is retrieved.

Thanks
Alex
