I’m using a Combo box control in Power Apps for a new app, but its default selection isn’t loading the expected data.

@AiswaryaKrishnakumar,

Hope you are setting the value in the DefaultSelectedItems property of the combo box?

What is the formula (Power Fx) you written in that ?

In my case, the registration form is split across two screens. On the first screen, I store the input values into a collection. On the second screen, I hide the fields from the first screen and set their default values using the LookUp function to retrieve data from the collection.

However, when I hide these fields, I receive an error indicating that required fields are missing (as they are marked required).

If I change them to not required, the record is created successfully, but the selected values in all combo boxes appear blank.

When I keep the fields visible and submit the form, all combo boxes retain their selected values correctly

Hi @MS.Ragavendar

Screen 1

ClearCollect(

col_new_proj_firstscreen,

{

var_ProjectName: DataCardValue_pmoob_projname_2.Value,

var_RequestDate: DataCardValue7.SelectedDate,

var_Program: DataCardValue_pmoob_program_2.Selected.'Program Name',

var_Entity: DataCardValue_pmob_entity_2.Selected.Value,

var_classification: DataCardValue_requestroute.Selected.Value,//classification

var_BriefScope: DataCardValue_pmoob_briefscope_2.Value,

var_Grouping: DataCardValue_Drp_Grouping.Selected.Value,

var_StrategicAlignment: DataCardValue_ExecInfoStrategicAlignment.Selected.Value,

var_ID: DataCardValue101.Value,var_comments:DataCardValue86.Value, var_Approvalpath:DataCardValue3_1.Selected.Value,var_Procurement:DataCardValue3_1.Selected.Value

}

);

Highligted fields except program is choices . Program is a lookup .In all these fields I used combobox .

In Second screen I have these fields hidden and their datacard values default selected property is set to

LookUp(Choices('StrategicAlignmentChoices'),Value= First(col_new_proj_firstscreen).var_StrategicAlignment)

LookUp(Choices('EntityChoice'),Value= First(col_new_proj_firstscreen).var_Entity),

LookUp(Choices('RequestTypeChoice'),Value= First(col_new_proj_firstscreen).var_classification)

LookUp('Program Registrations','Program Name'= First(col_new_proj_firstscreen).var_Program)
