Prevent Blanks in ComboBox Selection

 

I am trying to figure out a way to prevent blank cells from showing up in my CB selection as shown here (the series of commas are due to concatenating multiple blank fields  - these are what i am trying to get rid of):

Following is what is in ComboBox.Items:

Filter(CollPtAPrd,Value(GrpTot)=Max(CollPtAPrd,GrpTot))

 

Following is the applicable portion of the collection that is being used in the CB above:

ClearCollect(CollPtAPrd,
AddColumns(PtAProd,
     "GrpTot" , 1
   , "GrpLoc" , ""
   , "GrpBrd" , ""

There is a separate filter selection screen that works by incrementing "GrpTot" by one for each filter that is selected so that only those items with the highest 'GrpTot" value are shown in the CB. When multiple filters are selected, everything is fine in the CB. Of course, I would like the user to be able to see all products in the CB if no filters are selected. That is when I am having issues.

Hi @AGS94 ,

Which column do you use as the Display value within your ComboBox?

Do you want to remove the Blank value from your ComboBox?

 

I have made a test on my side, please take a try with the following workaround:

Set the Items property of the ComboBox to following:

 

Filter(
CollPtAPrd,
Value(GrpTot)=Max(CollPtAPrd,GrpTot),
!IsBlank(First(Split(DisplayColumn, ", ")).Result) && !IsBlank(Last(FirstN(Split(DisplayColumn, ", "), 2)).Result) && !IsBlank(Last(Split(DisplayColumn, ", ")).Result)
)

Note: The DisplayName represents the column in your CollPtAPrd collection, which you used as Display value within the ComboBox. I assume that the DisplayName column value is concatenated with three fields value.

 

 

Please take a try with above solution, check if the issue is solved.

 

In addition, if you want to see all products in the CB if no filters are selected, please consider set the OnChange property of the ComboBox to following:

 

If(
   IsBlank(ComboBox1.Selected.Value),
   ClearCollect(                              /* <-- Reset the CollPtAPrd collection */
CollPtAPrd, AddColumns(
PtAProd, "GrpTot" , 1,
"GrpLoc" , "",
"GrpBrd" , ""
) )
)
