Hi,

All of my widgets are using async request to fetch their data source business object.

But somehow I discovered that my widgets not longer fetched their data source business object asynchronously once I have used the daynamic dashboard.

p.s. I was using the webpart control that comes with .net 4 and my widget do request their datasource object asynchronously.

anyone have any ideal?

Thanks

Did you sniff the packs with fiddler ?

then we can learn that it sends async request or not .

Hi Berkay,

I am new to Fiddler, I can't see Fiddler able to sniff the packs from my widgets.

I will be much appreciate if you can contact me directly regarding this issue, so that I can direct you to one of our test site and try it out.

thanks.

Hi Berkay,

I have finally found out what is causing the problem.

Each of my widget is a user control that create by (contains within) another user control that has a control called - iucon:PartialUpdatePanel.
(http://www.codeproject.com/Articles/23768/Load-and-Display-Page-Contents-Asynchronously-with)

The reason for that is we want the user sees a loading icons while the widget fetching the data. If you have time to take a look at this PartialUpdatePanel from the link above you will see how it works...

The problem was when I have put this 'layer' in between Dynamic dashboard and my widget, the Async request does not works. But if I removed this 'layer', the Async request does works.

Could you possibly tell me whether it is possible to achieve this without using that PartialUpdatePanel? i.e. user see each widget with a loading icon while the widget fetching its data.

Thank you very much for your help.....

Regards

Hi Porson,

First way,

You can show loading icon by using postback mask property of widget type. If you set this property in every widget type from widget types editor , every widget shows loading mask separetly.

Second way,

You can use UpdateProgress control in your widgets. There is a sample in Dashboard Editor Page in sample application .

Hi Berkay,

Thanks again for the reply.

Regarding the methods that you mentioned, do these methods apply to when the page first load, not just when the widget is doing a post back.

The ideal is when user FIRST goes to the page, all the widgets on page will show their outer panel (header) with loading icon in the middle (or something) while they fetching the data asynchronously.

The contains of each widget will then appears whoever get their data first.

Meanwhile, I will try your suggestions and see.

BTW, All of the widgets already has the Postback Mask set with 'Processing...' but I couldn't see where this postback mask appears. Everytime I refresh an indivdual widget by clicking the refresh button, I can see 'refreshing ...' but not the postback mask 'Processing...'

And when I first go to the page, the complete page doesn't appears until all the widgets have the data.

????

Regards

Hello Porson,

If updatemode of updatepanel is conditional , widgets could not wait other widgets loading.

You can see this example from here.

There are many asynchrone widgets in this page.

Hi Berkay,

I had a look at the sample application related to the Asynchrone Widgets. Could you please let me know which one is the asynchrone widget please?

Is it the GoogleMap, Rss Reader,.... is it any of those widget with a timer control?

If so, is the timer control only used to trigger the post back to the server to check whether data is ready so the widget can do a databind?

Thanks again for the help

Regards.

Rss Reader and Silverlight widget load data asynchronously.

The Other widgets don't wait Rss Reader and Silverligt Widget loading process.
