Multiple Gallery Selection

(0) ShareShare
ReportReport
Posted on by daniellerodris 40

Hello!

 

I have a gallery with various items. On each line, I have a checkbox to select it from, and I also have a checkbox that selects all the lines. I need to create a lock so that when I reach 299 selected lines, I won't let any more be selected.

How to do this?

    @daniellerodris 

    Place a label outside of your Gallery (you can set the Visible to false as this is just a helper label) and set the Text property to:   CountRows(Filter(yourGallery.AllItems, yourCheckBox.Value))

     

    Set the DisplayMode of your gallery checkbox to :

        If(Value(theLabelNamefromAbove.Text)>=299 && !Self.Value, Disabled, Edit)

     

    You are done!

     

    This will disable all unchecked checkboxes while leaving the checked ones available in case the user wants to uncheck one.

     

    I hope this is helpful for you.
