Editing a Single Row of a Gallery

Posted on by CU06081315-1

Hello,

I've created a gallery with editable rows. My edit icon is set to toggle a variable (UpdateContext({varMCDisable: true});) to set the gallery as editable. Is there a way that I can set only a single row of the gallery to be editable as opposed to the entire gallery? I'm currently attempting to allow users to edit only their own entries:

If(

User().FullName = ThisItem.Operator,

DisplayMode.Edit,

DisplayMode.View

)

This works if I use a form to edit the entries, but if I attempt to edit in the gallery, it will open every entry to edit. Thanks for any advice.

Hi @cborde3,

Instead of setting the variable to true or false (will change all rows), save ThisItem to the variable and check whether the gallery item equals the saved variable item.

Save ThisItem to a variable:

UpdateContext({varEditItem: ThisItem})

DisplayMode of the controls:

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

If you want to combine it with your current Operator logic:

If( User().FullName = ThisItem.Operator && varEditItem = ThisItem, DisplayMode.Edit, DisplayMode.View )

If this solves your question, would you be so kind as to accept it as a solution.

Thanks!

Hi @cborde3 ,

Record cannot compare with Record in the condition, so ThisItem = varEditItem is incompatible. For your scenario, you need to add a column to the data source with default false values, on edit button update the value of own entry to true.

Gallery Items:

Your Data Source that includes a Y/N column with false values in it. I assume the column called "Editable".

OnSelect of Edit button:

Update(YourDataSource, ThisItem, {Editable: true})

DisplayMode of Controls within Gallery:

If(User().FullName = ThisItem.Operator && ThisItem.Editable, DisplayMode.Edit, DisplayMode.View)

OnSelect of the Save button:

Patch(YourDataSource, ThisItem, {Column1: Control1.Text, Column2: Control2.SelectedDate, Editable:false})

Best regards,

I indeed missed one small adjustment - my apologies. As correctly stated by @v-jefferni, comparing record values is not possible.

An easy workaround would be changing the ThisItem = varEditItem to comparing a unique field of that record (e.g ID) -> ThisItem.ID = varEditItem.ID

A neat alternative @CNT introduced me to is keeping your current way of working with the boolean value and adding ThisItem.IsSelected:

If( User().FullName = ThisItem.Operator && varMCDisable && ThisItem.IsSelected, DisplayMode.Edit, DisplayMode.View )

I hope this helps!
