Hi,

I have a gallery with 3 rows. I need to allow editing of individual rows in gallery which is working fine. I am able to save the data successfully as well.

Can please let me know on how to make the display mode as read only once the particular row is saved?

Add button OnSelect

Collect(
    yourCollection,
    {
        Name: "",
        Email: "",
        Designation: "",
        Contact: "",
        RandID:Rand()
    }
)

Add button Displaymode (to allow only 3 rows to be added)

If(
    CountRows(yourCollection) < 3,
    DisplayMode.Edit,
    DisplayMode.View
)

Gallery Items property

yourCollection

Gallery Edit icon

UpdateContext({varEditItem: ThisItem})

Displaymode of TextInput in Gallery

If(
    ThisItem.RandID = varEditItem.RandID,
    DisplayMode.Edit,
    DisplayMode.View
)

Hi Iantaylor2050

I suspect that setting varEditItem to zero will do the job. You should also do this at Screen OnVisible to initiate the variable as numeric as Blank() can be a number of possible formats.

Please click Does this answer your question if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it a Like.

Hi Iantaylor2050

Add this at the end of the Save and Delete button functions to make the local variable blank:

UpdateContext({varEditItem: Blank()})
