Show all items in a gallery if dropdown is blank

[Anonymous]

Hi,

I have a dropdown with information of a sharepoint list, de column of information is "Choice", so I conect the data to de dropdown with this formula:

Choices('Visitas para ventas'.'Canal Comercial')

So I have a gallery and a graphic that I need to see the information if I chose any option of the dropdown, I conect that with this formula:

Gallery

If(Dropdown1.Selected.Value = None ;'Visitas para ventas';SortByColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Dropdown1.Selected.Value);"{FilenameWithExtension}";Ascending))

Graphic

AddColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Dropdown1.Selected.Value);"Canal C";('Visitas realizadas'/'Visitas programadas'))

The problem is that I want to see all the records in the gallery and graphic if i don´t select nothing in the dropdown, Is there any code that I can use to do this.

Have you considered using the isBlank() function. 

Items = If (isBlank(Dropdown1.Selected.Value), 'Visitas para ventas', "ELSE apply the filter")

Have you try using IsBlank()?

If(IsBlank(Dropdown1.Selected.Value) ;'Visitas para ventas';SortByColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Dropdown1.Selected.Value);"{FilenameWithExtension}";Ascending))

Hi @Anonymous ,

I just tested with the same scenario. If your Choice column does not include a null value, then the default selected value will never be blank for this dropdown control. So all the above formulas won't work.

If you want to start with a blank item in the dropdown, you can set its Items property to a collection where the first element is blank. Set below formula in the OnStart property of your app:

ClearCollect(C1,{Value:""});;Collect(C1,Choices('Visitas para ventas'.'Canal Comercial'))

Then set below formula in the Items property of your dropdown control.

C1.Value

For Items property of your Gallery, set to:

If(IsBlank(Dropdown1.Selected.Value);'Visitas para ventas';SortByColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Dropdown1.Selected.Value);"{FilenameWithExtension}";Ascending)))

This works for me. Please go ahead and have a try.

Regards,

Mona

yes Mona, I remember that in one of my projects, I added a "-" to my choices and handled it that way. If we want to use the isBlank() function then we need to follow your suggestion and use a collection.

Hey @Anonymous 

By default, dropdown control selects its first item. You can have a combobox control in case you do not want to have a default value selected. You can set the "Allow Multiple Selections" toggle to off.

Can you try to update your expressions as:

Gallery
If(CountRows(Combobox1.SelectedItems) = 0 ;'Visitas para ventas';SortByColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Combobox1.Selected.Value);"{FilenameWithExtension}";Ascending))

Graphic
AddColumns(Filter('Visitas para ventas';'Canal Comercial'.Value = Combobox1.Selected.Value);"Canal C";(Value('Visitas realizadas')/Value('Visitas programadas')))

Hope this Helps!
