Select All option for combobox

(0) Share

Posted on by Incident-Manage

In the application I am building, I have a combo box that I am using the selection from to filter the gallery. If I select every available option in the combo box it filters correctly. I wanted to add a "Select All" ability as the combo box list has 36 items to accomplish this I added a check box that has the code similar to below and then set my combo box DefaultSelectedItems to the variable I am using that I called SelectedItems. My issue is when I select the check box it correctly selects all the items in the combo box but it doesn't engage the filter on the gallery.

If(
 Checkbox1.Value,
 Set(
 SelectedItems,
 [
 "Item 1",
 "Item 2",
 "Item 3",

 ]
 ),
 Set(
 SelectedItems,
 []
 )
)

hey @Incident-Manage

can u try this:

If( Checkbox1.Value, Set( SelectedItems, Filter(YourDataSource, true) // Replace YourDataSource with the actual data source name ), Set( SelectedItems, [] ) ); // After setting the SelectedItems, refresh the gallery Refresh(YourGallery); // Replace YourGallery with the actual gallery control name

Could you share your query for gallery?
If the combobox items fill up correct based on checkbox, you should get correct SelectedItems.

@Meekou below is the query for the gallery.
Filter( 'Application List', IsBlank(ComboBox1.Selected.Title) || ComboBox1.Selected.Title in ThisRecord.'Hospital(s)'.Value )

Hi @Incident-Manage ,

I assume 'Hospital(s)' is a multi-value Choice column and you are selecting multiple values in the Combo Box. If so

If( Len(ComboBox1.Selected.Title) = 0, 'Application List', Ungroup( ForAll( ComboBox1.SelectedItems As _Items, Filter( 'Application List', _Items.Title in 'Hospital(s)'.Value ) ), Value ) )
