Combobox Default

Posted on by R45

Hi all,

I have created a form where the records can be viewed again after submission (selected from left container thus populating the right container). The values inputted via text are shown using Parent.Default and ThisItem.'Field' for the dates. However, neither option works for the combo boxes' "default selected items property". See below submitted form where the bottom 3 fields are combo boxes and are not populated.

What is the best way to load the submitted data in the combo box, as shown for other fields? I have achieved the desired result for the "General Condition" field using a label over the combo box and setting default to ThisItem.'General Condition'. However, this has proven unreliable. Hoping for a better solution.

Thanks in advance.

@R45 - assuming the data types for all three fields are Single Line Text, the typical workaround is to apply the below onto the DefaultSelectedItems property:

{Value: Parent.Default}

Or:

{Value: ThisItem.'General Condition'}

Or alternatively force the correct record if using complex data types using:

LookUp( 'Your Data Source', 'General Condition' = Parent.Default )

Thanks for your response. I have reloaded the app and some of the text fields that were working before now no longer show. Is there a way to prevent this? It appears to not be an issue with a particular data type as it shows for some. I am using SQL Server as a data connection.

@R45 - they stopped working after you made a change to the DefaultSelectedItems property? or is this an unrelated question?

They stopped working once I reloaded the app, despite having made no changes to the default selected items property. If I add a new record it will show all of the values, however, this won't be the case upon restarting the app for some reason.

Thanks

@R45 - just so I understand it, you have now have a new issue unrelated to your initial question.

The issue is associated to specific DataCards (bound to Single Line Text fields in your data source) not populating with any values when you first start the app?

@R45 - I will need more clarity here.

Depending on what you have on the Item property of that Edit Form control, I would not typically expect the Form to be populated with anything when you first start the App. It will only populated once you have associated it to a record (e.g. from a Gallery selection).

So as I understand it, the Edit Form is correctly displaying nothing when you first start the app, but when you select an Item from the Gallery, all DataCards are not being populated?

I see the form as below when I open the app:
Where only part of the form is populated. I then click on the gallery and the fields are still not populated. The app works as intended if I add a new record though.

@R45 - could you create a new EditForm but without any of the customisations you made. Set the DataSource property to the same data source as the Gallery control, and set the Item property of the EditForm to something along the lines of:

'Your Gallery Name'.Selected

Then check if the DataCards correctly populate with the data based on the Gallery selection. I want to identify if the problem is to do with whatever customisations you might have made to your current EditForm.
