How to add user control in mvvm quick guide?


Asked by Kieran Hancock on Dec 08, 2021 FAQ



Step 3 − Add a StudentModel class in the Model folder and paste the below code in that class Step 4 − Add another StudentViewModel class into ViewModel folder and paste the following code. Step 5 − Add a new User Control (WPF) by right click Views folder and Select Add > New Item…
In this manner,
Below are a few reasons: Separation of concerns (each control has a view model only containing the information for itself, not for children); User controls are built so they can be re-used. Without the user controls to be able to have their own view models, how should one actually use user controls with MVVM?
Also Know, Now, let's have a list of records in MainViewModel according to which we need to display the child User Control in main UserControl and pass the datacontext for child control. We need to use ChildViewModel as the property of our MainViewModel and then, bind the ChildUserControl directly from XAML.
And,
Let’s have a look at a simple example in which we will be using MVVM approach. Step 1 − Create a new WPF Application project MVVMDemo. Step 2 − Add the three folders (Model, ViewModel, and Views) into your project.
Moreover,
ViewModel is the main point of MVVM application. The primary responsibility of the ViewModel is to provide data to the view, so that view can put that data on the screen. It also allows the user to interact with data and change the data.
