Hello,
I migrated recently all the way from dhtmlx 3.6 and I can’t seem to find a way to keep tabs loaded in the memory when they’re not selected.
I have iframes inside the tab content and it looks like it’s reloading each time I switch tabs.
How can I avoid that and keep them loaded when they’re not selected ?
Thanks
Unfortunately due to the VDOM usage, it is not available to keep the tabs in memory after the tab change
I understand the use of the VDOM, but there is no BeforeChange event that can be leveraged to let users know that they will loose whatever they are doing on that tab if they switch before saving in the case of an IFrame. Most users won’t find that acceptable. Please let me know if you have a solution to this issue.
We’re planning to add the beforeChange event for the tabbar in the next dhx.Suite update.
We have added the beforeChange event for the dhx.Tabbar in the latest dhx.Suite update (7.3).
It is allowing to validate and block the tab change if it is needed returning “false” from the beforeChange event

Here is a simple snippet as an example:
