I couldn’t find a right term to search about this in the feature.
I have a control that will load a very heavy data that embedding within a tab of of my MainWindow.
Test Case:
For testing I have a window, within this windows there are 2 tab. the first tab contain notthing. 2nd tab contain this user control.
In the 2nd tab I have a MessageBox.
Run this program and MessageBox popup right after the MainWindow was loaded.
How can I delay load this usercontrol/page until the tab is active?
Have you tried calling your load code only when the user control is visible?
The other suggestion would be to create you own tab control that only loads the content when the tab is visible. This would also allow you to create animations when a tab becomes hidden before the new tab is visible.
