We overrode the ListViews View using a GridView so that we could display the data in the format our users required. The issue that we encountered was that after we introduced MultiSelect, our drag and drop didn’t work as expected.

You could select multiple rows, but when you then clicked on the selection area to “drag” them, then it would unselect everything but the one you specifically clicked on.

Not the greatest of behaviors.

So the trick is rather simple, yet strange. Override the ListViewItem class, and use it to override the generated items.

Your new ListView

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Controls;
using System.Windows;
using System.Collections.ObjectModel;
using System.Collections;
using System.Collections.Specialized;
using System.Windows.Controls.Primitives; 

namespace Seekford{
    public class MyListView: ListView    {
        protected override DependencyObject GetContainerForItemOverride()
        {            return new MyListItem();
       }
     protected override bool IsItemItsOwnContainerOverride(object item)
      {
           return item is MyListItem;
       } 

     }
}

Your new ListViewItem

using System;
using System.Windows.Controls;
using System.Windows.Input;
using System.ComponentModel;

namespace Seekford{
      public class MyListItem : ListViewItem	{

        protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
        {
            if (IsSelected)
                return;
            base.OnMouseLeftButtonDown(e);
       }

        protected override void OnMouseLeftButtonUp(MouseButtonEventArgs e)
        {
            if(IsSelected)
                base.OnMouseLeftButtonDown(e);
        }
 }
}

Nice and easy! Kludgy, but seems to work.

Happy Coding!
