Simple- How To select an Item from a WPF combo box using coded UI

I have worked with coded UI for web applications but for the first time I am trying to leverage Coded UI for WPF. I want to perform a click on an item from a combobox But, I am unable to achieve the same here in WPF. I tried to loop through the items inside the combo box but It did not work. Tried with Search Property - No result. Also, was trying to figure out the AutomationElement stuff but not able to get a solution. It would be great if I can get an idea of the approach that needs to be followed to achieve the requirement.

I have captured the controls and want to play around with them. No record and playback.

You can use the WpfComboBox's SelectedItem property which takes the name of the item you want to select (as mentioned in my comment in yonder answer)

var myComboBox = this.UIMap.UIMainWindowWindow.UIItemComboBox;
var items = myComboBox.Items;
myComboBox.SelectedItem = items[0].Name;

or you can simply set the SelectedIndex if you already know the index of the item you want to set

var myComboBox = this.UIMap.UIMainWindowWindow.UIItemComboBox;
var items = myComboBox.Items;
myComboBox.SelectedIndex = 0;

or you can first click the combobox to get it expanded and then get the UITestControl for the item element and perform a click on it (unfortunately you have to manually click the combobox because it seems that the ExpandWhileSearching configuration it doesn't work on it)

var myComboBox = this.UIMap.UIMainWindowWindow.UIItemComboBox;
var items = myComboBox.Items;
Mouse.Click(myComboBox);
Mouse.Click(items[0]);

or

var myComboBox = this.UIMap.UIMainWindowWindow.UIItemComboBox;
var items = myComboBox.Items;
myComboBox.Expanded = true;
Mouse.Click(items[0]);

You would create the combobox object the same way you would in Html, just using Microsoft.VisualStudio.TestTools.UITesting.WpfControls namespace. For example:

public WpfComboBox tester
{
    get
    {
        WpfComboBox target = new WpfComboBox();
        return target;
    }
}

Then, you will create a UITestControlCollection object to store the .Items of the combo box.

UITestControlCollection comboBoxItems = tester.Items;

From here, you should be able to edit and set selected items ( tester.SelectedItem = comboBoxItems[0].ToString();) at will.
