Performance delay occurs when creating new instance of my custom class on while loop

Question

I have one custom popup wpf control ( Repeater Items control), In the repeater control, every time when press up/down creating im creating new instance of item control added to repeater item collection.

My problem:

I have one progress bar and my custom repeater item control in my application.

Eg: When press up/down keys in my custom control, progress bar animation stops for few milliseconds. this delay when occurs due to , creating new instance of item control when press up/down keys.

Creating instance of certain class cause performance delay in my case.

Any suggestion on this.

Thanks

Welcome to our Microsoft Q&A platform!

You can use Task when creating new instance of my custom class on while loop

 Task.Run(() =>
            {
              while loop
            });

Thanks.
