Click of a tab in Ultrawebtab takes long time to display data

pavani posted over 14 years ago

Hi,

i am using Visual studio 2008 , infragistics netadvantage 2009.2.

In my application i am using an ultrawebtab with 5 tabs, with in each tab labels were there and the data was displayed from database. the problem here is that when i click the first tab the data is being displayed good , but when i click the second tab it is taking 4-5 seconds to render the second tab data.

My requirement is that the tab click and the display of the data should be fast. i used async postbacks but it is of no use.

Please find the attached code for reference.

Any help on this is greatly appreciated.

Thanks,

bowcreek.

Hi Bowcreek,

I looked at your codes and noticed following things.

1. UltraWebTab has enabled AsyncMode and it is located inside of UpdatePanel. That combination is not supported, because script managers of UpdatePanel and UltraWebTab are not compatible.

2. UltraWebTab has enabed AsyncMode and it contains PopupControlExtender as a child. That combination is not supported. AJAX controls can not be located in UltraWebTab with enabled async mode. Same reason as for #1.

3. UltraWebTab has enabled AsyncMode and enabled AutoPostBack. That combination has no sense, because AutoPostBack triggers full postback and AsyncMode becomes irrelevant.

I suggest you to
1. disable AsyncMode of UltraWebTab
or
2. remove UpdatePanel and PopupControlExtender.

If you select #2, then you should keep in mind that AsyncMode in tab does not speed-up processing time on server, but keeps page alive which async postback. It also reduces size of response-html sent by server to client compare to the size of whole page. Only content of UltraWebTab is send. But if page contains only UltraWebTab and no other "big" controls located outside UltraWebTab, then there is reduced response neither, and overall time on postback will be almost the same for full and async postbacks.

I have a similar problem. Using UltraWebTab v.7.1. Removed all the code from Tab Click event and even then it takes 5-6 secs to postback and display the page back when i click on any tabs. Any ideas?

Thanks
