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.

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. As you can see from the first examples, manually defining the items of a ComboBox control is easy using XAML, but you will likely soon run into a situation where you need the items to come from some kind of data source, like a database or just an in-memory list. Using WPF data binding and a custom template, we can easily render a list of colors, including a preview of the color:. It's actually quite simple: In the Code-behind, I obtain a list of all the colors using a Reflection based approach with the Colors class. This gives us a complete list of colors, with minimal effort - and it looks pretty good too, right? In the first examples, the user was only able to select from our list of items, but one of the cool things about the ComboBox is that it supports the possibility of letting the user both select from a list of items or enter their own value. This is extremely useful in situations where you want to help the user by giving them a pre-defined set of options, while still giving them the option to manually enter the desired value.

Name Gets or sets the identifying name of the object. When that happens, I read the selected color once again using Reflection, as described above and then use the selected color to create a new background brush for the Window.
