Here, I will explain how to change a combo box value based on a button click.

Example,

I have a SharePoint Online list [IT Service Request], that has various columns like:

Column Name	Data Type
Employee ID	Title
Employee Name	Single line of text
Issue	Choice [“Laptop”, “Network”, “Outlook”, “Other”]
Issue Handled By	Person or group

Now let’s see how to achieve it:

• Create a Blank canvas app -> Connect to the SharePoint Online list as shown below:

Step 1: [Insert a Dropdown control and connect to an above SharePoint list column]

• Insert a Dropdown control -> Set its Items property to:

Choices('IT Service Request'.Issue)

Where,

1. IT Service Request = SharePoint list name
2. Issue = SharePoint list choice column name

Step 2: [Insert a Combo box control and connect to an Office365Users]

• On the +Add data -> Connect the Data source to an Office365Users.

• Insert a Combo box control -> Set its Items property to:

Office365Users.SearchUser({searchTerm: cmb_IssueHandledBy.SearchText})

Step 3: [Insert a button control and create a variable to set a combo box value]

• Insert a Button control -> Set its OnSelect property to:

Set(
    varIssue,
    If(
        DrpIssue.Selected.Value = "Laptop",
        "Henrietta Mueller",
        If(
            DrpIssue.Selected.Value = "Outlook",
            "Lynne Robbins",
            If(
                DrpIssue.Selected.Value = "Network",
                "Lidia Holloway",
                "Megan Bowen"
            )
        )
    )
)

Where,

1. varIssue = Provide the variable name
2. DrpIssue = Dropdown control name
3. Laptop, Outlook, Network = SharePoint list choice column values

Step 4: [On the combo box control, assign a variable to set a combo box value]

• Select a Combo box control -> Set its DefaultSelectedItems to:

[varIssue]

Where,

1. varIssue = Assign the variable name here

• Save, Publish, and Preview the app, when a user selects a value from the dropdown control [Issue] and clicks on a button control. The combo box will automatically select a user who is responsible for that specific issue.
