Unable to set ScrollPosition in Sub Activity_Create

[Pantelis]

Hi

I am trying to set the Scrollposition property of one HorizontalScrollView with the code:: LongLayout.ScrollPosition = 700
If i put the code in a sub event of a button like button1_click it works ok.
But if i put the same code just before the end of "Sub Activity_Create" nothing happens. The ScrollView remains in its original scroll position.
Setting another property like "LongLayout.Height = 300" work ok on "Sub Activity_Create"
Why this happens?

Thanks

This happens because the HorizontalScrollView smoothly scrolls to the position. You should change your code to:

LongLayout.ScrollPosition = 700
DoEvents
LongLayout.ScrollPosition = 700
DoEvents

Note that this code is also wrong. You should use 700dip.

Thank you Erel. The code must be writen twice as in your example?

If I remember correctly it needs to be set twice.

So far I have used this "technique". Is it still valid?

Yes for B4A til version 6.80

Since version 7.00, try to use use this:

Sleep(0)
LongLayout.ScrollPosition = 700dip

At least it works with the ScrollView.
