Switch images with variable value

Posted on by DennisJarnstal

Hi,

I am building a function that turn pages and have setup a switch function for the text on each page that works great. However when i try to setup the function for images it doesnt work and i am unable to figure out why.

Switch(varPage;1;ThisItem.Pic1;2;ThisItem.Pic2)

Pic1 and Pic2 are the column names. Each time i click the next button the variable increases by 1, so this function will go on for about 20 columns. Just using ThisItem.Pic1 works of course but when put in the switch function it doesnt, and the same function on the text field works great and switches between texts no problem.

Thanks for any help possible.

@DennisJarnstal - I would suggest to use variable inside switch and update the value to the same variable.
Switch(varPage;1; Set(image,ThisItem.Pic1);2;Set(image,ThisItem.Pic2))

@Bilakanti where should i be updating this variable image? If i set the image value to image variable i need to update that variable switch somewhere else but i dont think i understand where i should do that.

If i set the image value to the mentioned code it wont accept since its only setting variable but not using the variable.

Setting it in the button for next gives an error, tried to set it up like this on the button: Set(varPage; varPage + 1) && Switch(varPage;1;Set(varImage;ThisItem.Pic1);2;Set(varImage;ThisItem.Pic2))

Thanks for your quick reply earlier 🙂

@Bilakanti Sorry if im explaining it poorly 🙂 I will explain more what i mean.

The button that updates my current text fields has this code in the OnSelect field:
Set(varPage; varPage + 1)
and the text field change with this code in the Text field, this works fine:
Switch(varPage;1;ThisItem.Textsid1;2;ThisItem.Textsid2)

I am trying to update the image to change with the varPage update and tried putting the following in the image property:
Switch(varPage;1;ThisItem.Pic1;2;ThisItem.Pic2)
This however doesnt work, and I now tried your approach but I cant see where i would set and update a new variable for the image. I called it varImage in the code you mentioned and tried setting the image property to varImage and updateing it along with the varPage update in the OnSelect of the button, but that didnt work, and i tried the code directly in the image property aswell. I have images attached.

Hi @DennisJarnstal,

So Pic1, Pic2 are image columns in SharePoint and you are absolutely sure there are images stored in those columns?

@Akser yes there are images in the image columns, but empty columns give no error when displayed so i dont think it needs to be, or am i incorrect? If i for example use Pic3 column, with ThisItem.Pic3, which has no image it just displays and emtpy image field in power apps but no error

@DennisJarnstal can we try the following just for testing purposes?

Let's introduce a test variable after you set your page variable:

Set(varPage, varPage + 1); Set(varTest, false); Set(varTest, true);

And use this instead

If(varPage = 1 And varTest, ThisItem.Pic1, varPage = 2 And varTest, ThisItem.Pic2)

@DennisJarnstal Can you try it using If condition?
If(varPage1 = 1, ThisItem.Pic1,If(varPage = 2,ThisItem.Pic2))
