[Solved] Performance with RAD Ajax

[Jacques Woolston]

Hi,

I have some performance issues with RAD Ajax and am after some advice of how I can get better performance out of my app by better using my RAD controls and RAD ajax... I currently have a RAD tab strip across the top of my page containing 6 tabs each tab containing many controls and sometimes a lot of data...

I'm after a way of only posting back partial data and doing partial updates to the page but still using the RAD tab strip and reducing the amount of data passed back and forth on each AJAX request..

Any help appreciated.

I've just done a little more testing, to give you an idea of my perfromance I'm getting a response back from the server which is 104Kb and it's taking 11344ms from postback to finish. Not great!

Would AJAXifying the tabstrip and making all controls.visible=false which are not in the active tab make my page run faster?

Hi Jacques,

You have two options:

• set the RenderSelectedPageOnly property of the MultiPage control to true. This will render only the active (selected) pageview and the others will be requested on TabClick, which you can handle by ajax.
• Remove the MultiPage control and use standard asp:Panel in which you are loading corresponding data from user controls dependent on the Tab clicked.

Hope this helps.

All the best,

Hi,

We ran into this issue a while ago.  What we did was initially loaded only the first tab's data, and then on the first tab click only we did a postback to the server to obtain more data for the page views.  On subsequent tab clicks, it was all handled in javascript.  I created a sample project a while ago, but I'm not sure how to post it in here.

Telerik, can you assist me with posting that sample project?

Hi,

I have set RenderSelectedPageOnly to true and this solved my issue initaly but now I have page validation issues across the tabs, please see thread: http://www.telerik.com/community/forums/thread/b311D-baadck.aspx

If I use option 2, would this solve both of my issues? Also I'd be interesed in seeing the sample project Jim has created if this solves the problem.

Thanks
