A ComboBox control is an items control that works as a ListBox control but only one item from the collection is visible at a time and clicking on the ComboBox makes the collection visible and allows users to pick an item from the collection. Unlike a ListBox control, a ComboBox does not have multiple item selection. The Button control is used to show or hide available items and Popup control displays items and lets user select one item from the list. The TextBox control then displays the selected item. The Width and Height properties represent the width and the height of a ComboBox. The x:Name property represents the name of the control, which is a unique identifier of a control. The Margin property sets the location of a ComboBox on the parent control. The HorizontalAlignment and VerticalAlignment properties are used to set horizontal and vertical alignments. The code snippet in Listing 1 creates a ComboBox control and sets the name, height, and width of a ComboBox control. The code also sets the vertical and horizontal alignment of the ComboBox and sets the margin. The following code snippet sets the IsSelected property of a ComboBox. Now we will add items to a ComboBox at run-time.

Hi, I want to store ComboBox selected Item in a Variable so, that I can call or retrieve the variable later according to my needs. But I don't know How Can I do that? I give you an example, suppose if my ComboBox name is cmb1 and I want to store it's selected Index into an integer variable then my variable declaration would be. But I don't know How Can I do for ComboBox selected Item, because selected Item is Object not any integer or string that's why most of the time I get compiler error I also try to declare it using Var but I don't get my expected result. Actually, I can do that by just storing the selected index but if there any item source changes happens then all the previous selected index will remove. I have to match the pattern somehow. You cannot rely on selected index, nor would you want to.

The ComboBox control is in many ways like the ListBox control, but takes up a lot less space, because the list of items is hidden when not needed. The ComboBox control is used many places in Windows, but to make sure that everyone knows how it looks and works, we'll jump straight into a simple example:. In the screenshot, I have activated the control by clicking it, causing the list of items to be displayed. As you can see from the code, the ComboBox, in its simple form, is very easy to use. All I've done here is manually add some items, making one of them the default selected item by setting the IsSelected property on it. In the first example we only showed text in the items, which is pretty common for the ComboBox control, but since the ComboBoxItem is a ContentControl, we can actually use pretty much anything as content. Let's try making a slightly more sophisticated list of items:. This gives us full control of the content as well as the text rendering, as you can see from the screenshot, where both text color and image indicates a color value.
