Bind Power Apps text input values in a dropdown control

[Hemashree]

Hi Members,

I have a requirement in Power Apps where I want to populate or bind the text input values in a Dropdown control.

Scenario:

I have a Power Apps Text input control [Single line], Dropdown control, and Button Control. I will enter one value inside the text input box and then click the Button.

For example, if the user provides Completed in the text input control and clicks on the button 5 times, the dropdown will have the 5 values of Completed.

But in my case, the text values are binding in the dropdown control but if I click on the button control again and again, the dropdown values do not increase.

For example, If I click on the button control 4 times, the dropdown value is only 1 item Completed. But I need the four values of completed.

In the button control's OnSelect property, I have put the below code:

UpdateContext({Status3:Split(txt_Status_1.Text, Char(10))})

Can anyone please suggest how I can resolve this? Thanks in advance!

Hi @Hemashree ,

It looks like you are trying to split the text entered in the 'txt_Status_1' input control by a newline character (Char(10)) and then update a context variable ('Status3') with the result. However, if you want to accumulate the values in the dropdown each time you click the button, you should use a different approach.

The 'UpdateContext' function sets a context variable to a specified value, and it doesn't accumulate the values. Instead, you can use a collection to store the values. 

1. Create a collection to store the values. In the 'OnSelect' property of the Add button insert this formula:

Collect(StatusCollection, Split(txt_Status_1.Text, Char(10)))

Here, 'StatusCollection' is the name of the collection. You should create this collection in the 'OnStart' property of your app or somewhere else appropriate. Make sure it's created before you use it.

2. Bind the dropdown control to the collection, In the 'Items' property of the dropdown control insert this collection name,

StatusCollection

This will make the dropdown show the values from the collection and add the new values to the existing ones in the collection.

Now, each time you click the button, it will add new values to the collection, and the dropdown will show all the accumulated values.

Remember to initialize the 'StatusCollection' collection appropriately, for example, in the 'OnStart' property of your app:

ClearCollect(StatusCollection, [])

This initializes an empty collection at the start of your app.

Thanks!!!
