How do i stop Drag Select on Themed Data Grid ?

Hello,

The open source DataGrid add-on we provide just has some extensions for the native WPF DataGrid.  Could you tell us exactly how to repro this scenario in one of our samples so that we can see what you mean, and whether it's something that would need to change in our code or in the native WPF DataGrid?

Hi

Its thee simplest case --

XAML Code

<Window x:Class="ActiproDragSelectSample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:datagrid="http://schemas.actiprosoftware.com/winfx/xaml/datagrid"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <datagrid:ThemedDataGrid ItemsSource="{Binding Items}">
            <DataGrid.Columns>
                <DataGridTextColumn Width="Auto"
                                        Binding="{Binding Path=.}"
                                        Header="Name" />
            </DataGrid.Columns>
        </datagrid:ThemedDataGrid>
    </Grid>
</Window>

 c# code

using System.Collections.ObjectModel;
using System.Windows;

namespace ActiproDragSelectSample
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.DataContext = this;
            Items = new ObservableCollection<string>();
            Items.Add("Hi");
            Items.Add("Hello");
            Items.Add("1");
            Items.Add("2");
            Items.Add("3");
            Items.Add("4");
            Items.Add("5");
            Items.Add("6");
            Items.Add("7");

            InitializeComponent();
        }

        public ObservableCollection<string> Items { get; set; }
    }
}

in this example, if you mouse down on row  and move your mouse to rows below, it selects all the rows, i want to stop this behaviour.

it should only select when shift or ctrol keys are pressed that too on click not on mouse move.

selection on mouse move makes drag drop impossible.

Thanks

hi

any solution that you can suggest ?

Thanks

Hello, in our last post we suggested possibly overriding OnMouseMove since that's where most of Microsoft's logic for this seems to be.  If you use Reflector, you can browse it and see for yourself.
