Using HorizontalViewPager1 instead of Canvas and Imagespirite

[raberan2023]

Hello Tim,

I have tried since two weeks to select an image by select page number 604 from select page menu which is the last item in the menu but when I move to the right and left side there is some error and should restart the app again.

Probably the logic shown here:

Using HorizontalViewPager1 instead of Canvas and Imagespirite

Perhaps something like this: hzpLogicRTLLastPageListSelect.aia (61.2 KB) I used a listpicker to display the pages that "can" be picked: [image] then afterPicking, assigned the desired pages to each of the vertical arrangements, then scrolling to the "first" pager component. [image] Note: this could be onerous once you have hundreds of pages, so your textbox approach for setting the page number may be better, with a check that it can be picked.

Hello Tim,

I think I have done something different in my app because when I select the last item in select page menu it shows

I have replaced to this block instead of the previous one

You will need to debug your app to find out what is happening:

Here is your problem, as indicated in the error message:

You requested the 6th item of the list, but there are only 5 items (one of them repeated...)

Hello Tim,

Would you please help me to solve the problem. I have replace the variable block and put sura instead of currPageList to show sura items in the ListPicker.

I hope you can solve the problem for me.
Thank you so much Tim

You have the working blocks and variables. Look at what you need to change.

I need to show part1, part2... like this

but when I select part6 and move to the right it shows error

[raberan2023]

Hello Tim,

I am sorry to disturb you.
I tried to do it but believe me I am not able to do it

part1, part2,part3,part4,part5,part6 in Sura variable are subjects inside a page

1,1,4,6,6,6 in listStream variable are page1,page1,page4,page6,page6,page6

Hello Tim,
