两个控件先于其他控件

Question

I have on a form a UserControl that I use as a Data-Entry form. I show and hide it constantly with new data.

Often (not all the times) the same two memo-boxes are shown on the screen first for a second, and then the full control is visible.

I found this link, I'm not sure if that's my solution, but in any case I don't know where to call it and when.

EDIT: I noticed that it happens 'only' if the program is idle for a couple of minutes. I could show and hide the control 10 times one after the other no problem. but if I hide it and show it again after 2-3 minutes then I get this behavior.

I guess it has to do with the time it takes to reconnect to the MsSQL database to pull the data. But how can I tell this 2 boxes to stay invisible like there parent until the parent is ready to show?

Answer 1

This is really sloppy and there is probably a better solution but what if you tried something like this.

If SlowControl.visible = True Then
FastControl1.visible = True
FastControl2.visible = True
End If

I'm not sure if that will work since i don't know how to replicate the problem to test but try it out and see if it delays the 2 that are ahead of the game a bit and doesn't show them until the others show.
