How to populate a combobox value based on a text column?

Hello,

I have an app with a SharePoint list column that is a single line of text and in Power Apps it was a textinput. Due to data entry inconsistencies, the textinput was covered with a combobox of predetermined values. The combobox values are a collection of a separate sharepoint list items.

Within power apps, for submission, users now select the value from the combobox and the combobox populates the value into the textinput.

A new feature lets users come back and edit the values within a new powerapps screen. On opening the selected item, the textinput populates with the correct text data for ThisItem.column1 but the combobox understandably stays blank.

How do I get that combobox to also populate with the submitted value for ThisItem until the user selects a new value which should update the combobox AND the textinput?

@ngreen - seems highly overengineered to keep both a Text Input control and a ComboBox control in sync. Regardless, you can "force" a Value into the DefaultSelectedItems property of the ComboBox using:

{ Value: ThisItem.column1 }

Or alternatively populate the DefaultSelectedItems property with a Record:

LookUp( 'Your Collection', Column1 = ThisItem.Column1 )

It is over engineered, but I was worried about data loss to switch the column fully to a choice column. I will test your feedback tomorrow morning and get back to you on if it worked for me or not. Thank you!

@ngreen - you are not changing data types - you can continue to keep the Single Line Text field. You just do need to remove Text Input control and run everything from your ComboBox control.
