Hi. I have a problem on the user control. My user control is movable, but most frequently, when I move the user control to other place inside the form, my user control disappear. My User control is flickering. And it exceeds within the boundary of the form. Meaning, I wasn't able to view some of it because it moves/exceeds to the boundary of the form. :)

Without seeing code I would guess you are having docking issues.

There are several reasons for your problem,
this.Controls.Add(usercontrol1) may need addressing.

Here[^] is a MS link.

And Here[^] is c#Corner link.

I hope they help.

If not, please supply more information.

When you move it, do you do so from within the control, or from the form?

If the former (i.e. this.Location = new Point(x,y);) then you will need to have some way to pass the limits of it's movement through from the form. Remember that the form can be re-sized, and so the control limits are changeable.

If the latter (i.e. myControl.Locaion = new Point(x, y);) then you need to check before you set the location, and ensure it is within the body of the form.

Sorry if that seems obvious, but that's the way it goes. If you don't check limits and allow for them, then it ain't going to work correctly!
