Programatically bringing a Datagrid row into view in WPF, MVVM

datagrid, mvvm, wpf

Solution

For the regular WPF `DataGrid` you can use `ScrollIntoView`. In your view hookup the SelectionChanged event to the following in your view code-behind cs file.

private void OnSelectionChanged( object sender, SelectionChangedEventArgs e )
{
    Selector selector = sender as Selector;
    DataGrid dataGrid = selector as DataGrid;
    if ( dataGrid != null && selector.SelectedItem != null && dataGrid.SelectedIndex >= 0 )
    {
        dataGrid.ScrollIntoView( selector.SelectedItem );
    }
}

Problem

I would like to bring a row of my data grid into view programatically. I have a more than 100 rows. When I create a row(which I am doing by adding an item to a observable collection) I would like that new row to be selected and bring that into view. I was able to select the new row in my code but could not do the scrolling. More over I want the first cell of the row to be in edit mode so that the user can input text. I am following MVVM pattern for the application and would like to keep zero code in my views. How Can I achieve this? Any help or suggestion will be appreciated.... Update: This what I did in my XAML ``` <telerik:RadGridView ItemsSource="{Binding AllPartClasses}" SelectedItem="{Binding SelectedPartClassViewModel, Mode=TwoWay}" SelectionMode="Single" IsSynchronizedWithCurrentItem="True"> ``` in my view model I did this ``` void AddNewPartClassExecute() { PartClass newPartClass = new PartClass(); PartClassViewModel tempPartClass = new PartClassViewModel(newPartClass); tempPartClass.IsInValid = true; AllPartClasses.Add(tempPartClass); SelectedPartClassViewModel = tempPartClass; Global.DbContext.PartClasses.AddObject(newPartClass); //OnPropertyChanged("AllPartClasses"); } public PartClassViewModel SelectedPartClassViewModel { get { return _selectedPartClassViewModel; } set { _selectedPartClassViewModel = value; OnPropertyChanged("SelectedPartClassViewModel"); } } ``` It did not work for me.
