How to display combobox field value in Text label after submitting canvas app?

[Anonymous]

Dear all, 

I am trying to use text labels to display chosen values in the Canvas app Combobox after they have been saved to the SharePoint.

The combobox gets its values from the external SP list and uses Update ={Value:cmb_Name.Selected.Result} to submit its inputs to the SP list.

I have added a text label in another screen with Text = cmb_Name.Selected.Result in order to display users what has been entered in another screen. However, after the forms are submitted the text label appears blank even though, there is a selected item in the Combobox. 

I have tried setting Text = Text(Datacard_Name.Default), but then receive an error that the text function has invalid arguments. Probably that is not a very logical solution after all.. Perhaps someone could advise if it possible to solve it and if yes how?

@Anonymous ,

On the OnChange of the Combo Box, set a Variable

Set(varDDValue,Self.Selected.Result)

and make the Text of the Label 

varDDValue

I believe your problem is that your combobox in your form is not being set to the default items.

In order to resolve this, you will need to set the DefaultSelectedItems property of the combobox.  To do so, you need to match the record of the Items property.  

I am going to assume, since you mention Result in your formula, that you are using a Distinct function in your Items property.

If so, then set the DefaultSelectedItems property to :

{Result: Parent.Default}

I would then refer to the form updates property to get the value from the record in the label in the other screen:

Label Text property:

YourFormName.Updates.yourColumn.Value

I hope this is helpful for you.

hi @RandyHayes , thank you.

Correct, I am using Distinct function in the Combobox's Items property. I did make the changes you suggested. It work when I am filling in the form, but when it is submitted, the text label shows [object Object] value, while the Combobox shows the selected item. Is this an expected result?
