Often collection data is better presented in a tabular view and better edited in a form view. Such UX approach is referred by our clients as “Popup editing in RadGridView”.

With the help of the new RadDataForm and the good old RadGridView a few lines of code are needed to accomplish this.

To have this working we need to :

1. Bind RadGridView to a collection IEditable and INotifyPropertyChange objects.

this.RadGridView1.ItemsSource = Person.GetSampleListOfPersons();

2. Bind a RadDataForm  to the current item of RadGridView

 

 <telerik:RadDataForm CurrentItem="{Binding CurrentItem,ElementName=RadGridView1}" …

3. Handle  the button event to show RadDataForm when needed.

private void Edit_Click(object sender, RoutedEventArgs e)
        {
            this.RadGridView1.CurrentItem = ((Button)sender).DataContext;
            this.RadDataForm1.Visibility = Visibility.Visible;
            this.RadDataForm1.BeginEdit();
        }

4.Handle the EditEnded event of RadDataform to hide it when no more needed.

void RadDataForm1_EditEnded(object sender, Telerik.Windows.Controls.Data.DataForm.EditEndedEventArgs e)
    {
        this.RadDataForm1.Visibility = Visibility.Collapsed;
    }

That is all you need to have  popup editing in RadGridView .
