delete screen confirmation

[Anonymous]

How can i do for make a validation screen when user delete data ?

When user use gallery for read data i give to him a possibility to delete some items, when he click on icon all is ok with the remove function.

i want better way, after he clic on icon, he have a new screen "are you sure you want to delete this entry ?" and he have choice beteween yes or no.

- If yes item is delete and navigate to other screen

- If no nothing happens and back to list of item

Hi Giulian,

It can be achieved by using Updatecontext function in you app. Please check this documentation for a reference:
https://powerapps.microsoft.com/en-us/tutorials/function-updatecontext/

And hope what I have done could be a reference for you:
1. Add three screens, on my app, they are Screen3, Screen4, Screen5.
2. My app is connecting to SharePoint list.
3. On Screen3, add a Gallery control, set its Items property as the data source “ListB”. Then add a Button control to the Gallery and name it as “Delete”, set its OnSelect property as:
Navigate(Screen4,ScreenTransition.Fade,{Text:"are you sure to delete the item",show:true})
4. On Screen4, add a Text box control, set its Text property as “Text”.
Add two button controls, Name them “Yes” and “No”, set the Visible property of them as “show”.
5. Then set the “Yes” button’s OnSelect property as: Remove(ListB,Gallery1.Selected);Navigate(Screen5,ScreenTransition.Fade)
“No” button’s OnSelect property as: Back(ScreenTransition.Fade)

Hope my steps could be a reference for you. Please try if this and let me know if this works for you.

If you need more help please feel free reply.
