c# - Initialization of tabs in tabControl -

-

I am using tab control with multiple tabs (& gt; 10), and each tab has UserContol but Tabs start each app when I start my app. This is slowing down my program. I want to run my user control only when I click on it How do I do this?

You should improve your user control that they do not display content as long as you get active / visible Give them a way to activate , when the tab has a tabront call when the selected tab is created.

Alternatively, you can not add user control to the tab page content in the designer. Instead of activating tabs, create your UserTrint instead But this will make them invisible in the designer.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
