How to move WPF DataGrid Rows using Drag and Drop?

Question

I followed an example from http://www.hardcodet.net/2009/03/moving-data-grid-rows-using-drag-and-drop I am pretty sure I copied all the codes yet strangely I can't see any Drag and Drop effects?

Anyone please have a look at the copied codes? https://www.dropbox.com/sh/e3hgg8kbfjqx21d/AADyTdHQsg1BOcPGePbBnt1ga?dl=0

Answer 1

I analyzed your code and found the issue.

the issue occurs because you've accidently used System.Windows.Controls instead of Microsoft.Windows.Controls for the reference of DataGridRow used in the following line

var row = UIHelpers.TryFindFromPoint<DataGridRow>((UIElement)sender, e.GetPosition(shareGrid));

so modify the following reference in MainWindow.xaml.cs

using System.Windows.Controls;

to

using Microsoft.Windows.Controls;

Let me know if this helps
