Question

I have a xaml names Customer.xaml like this:

<Grid x:Name="customview" >
   <StackPanel x:Name="CustomPanel" > 
      <TextBox x:Name="CustomText" />
    </StackPanel>
</Grid

Using MVVM I have created ICustomerviewmodel and Customerviewmodel like this:

public interface ICustomerviewmodel 
{
     ICommand SaveClientCommand { get; }
}

public class Customerviewmodel : ICustomerviewmodel , INotifyPropertyChanged
{
   ......
   private void ExecuteSaveClient()
   {
     //
   }

My question is how I could get the value of
inside the function ExecuteSaveClient() to save this?

• You should declare a string property in your view model say:

  public string CustomText { get; set; }

• Assign datacontext of customview to be your viewmodel int the constructor, hope this grid is in a UserControl or Window:

  this.customview.DataContext = new CustomerViewModel();

• Bind to that property:

  <TextBox x:Name="CustomText" Text="{Binding CustomText}"/>

• Implement INotifyPropertyChanged, if TwoWay binding and notification are required.
