TabControlExt preload

Hello

Is there a way to preload content in TabContolExt to avoid delay when a new TabItem with big content is added ?

Thank You

Hi Janusz,

Currently, we don’t have an option to Preload the tab item content in TabControlExt to avoid the time delay. However, we have a solution that, whether it meets your requirements or not, is dependent on the application and control loaded in the tab item. So, please kindly check the solution from the below sample,

Sample: https://www.syncfusion.com/downloads/support/forum/172467/ze/TabControlLoad1985206796

Please let us know your concerns.

Regards,
Sudharsan

I would like to programmatically add TabItem with big content which should be previously preloaded to avoid display delay. Could You please look at attached sample project ?

Hi Janusz,

You can be able to achieve the “TabControlExt PreLoad the TabItem” requirement by invoking TabControl loaded event and load the tab item content. So, we have modified the sample and attached from the below location,

Sample: https://www.syncfusion.com/downloads/support/forum/172467/ze/TabControlExPreload-2025723080

Please check the above sample and let us know. If we misunderstood the query, Please share more details about the requirement. So, it will be helpful to provide you the solution at the earliest.

Thank You, but that is not exactly what I need. I have found that Sacha Barber's solution

 (https://stackoverflow.com/questions/2193166/how-do-i-prerender-the-controls-on-a-tabitem-in-wpf)

does the trick.

It applies to to stanard TabControl. Is this solution possible when inheriting from Syncfusion's TabControlExt ?


Kind regards

Janusz Bieńkowski.

Hi Janusz,

Sorry for the delay.

Now, we have modified your sample as in the Syncfusion TabControlExt control. Now, it works by preloading the content in the TabControlExt as the same as MS TabControl. Please find the sample below,

Sample:  https://www.syncfusion.com/downloads/support/forum/172467/ze/TabControlExPreload791118308

Please check the sample and let us know your concerns. We are happy to assist you.
