DataGrid clear all text on Ctrl + C, Version: 0.10.0-preview5

[sn4k3]

When copy data with Ctrl + C all selected rows are emptied Data is copied to clipboard as expected

Version: 0.10.0-preview5

<DataGrid 
                    CanUserReorderColumns="True"
                    CanUserResizeColumns="True"
                    CanUserSortColumns="True"
                    GridLinesVisibility="All"
                    IsReadOnly="True"
                    ClipboardCopyMode="IncludeHeader"
                    Items="{Binding SlicerProperties}">

Before Copy:

2 row copied

Ctrl + A & Ctrl +C

Any updates?

There is a PR to fix this problem https://github.com/AvaloniaUI/Avalonia/pull/4722

But it is better to solve problem with TwoWay bindings instead, because current DataGrid clipboard implementation should "just work" https://github.com/AvaloniaUI/Avalonia/issues/4721

[FoggyFinder]

Yeah, I saw these PRs/issues, maybe there is some workaround for now?

[FoggyFinder]

Answering to myself, an obvious one:

1. Set ClipboardCopyMode to None
2. Subscribe to KeyUp (or similar) event and write logic there

Further note:

I'm also getting this: System.NotSupportedException: 'Two way bindings are not supported with a string format'

When using this property as bidding:

public IEnumerable IssuesGridItems 
        {
            get
            {
                if (!IsFileLoaded || DataContext is null) return null;
                if (Settings.Issues.DataGridGroupByType || Settings.Issues.DataGridGroupByLayerIndex)
                {
                    var groupView = new DataGridCollectionView(SlicerFile.IssueManager);
                    if (Settings.Issues.DataGridGroupByType) groupView.GroupDescriptions.Add(new DataGridPathGroupDescription("Type"));
                    if (Settings.Issues.DataGridGroupByLayerIndex) groupView.GroupDescriptions.Add(new DataGridPathGroupDescription("StartLayerIndex"));

                    return groupView;
                }

                return SlicerFile.IssueManager;
            }
        }

Wont happen if i feed DataGrid.Items="{Binding SlicerFile.IssueManager}" directly on XAMAL

Hey @sn4k3 if you're still looking for a solution, you can set ClipboardContentBinding and this will let the copy command work as expected.

Happy coding, Tim

Any sample arround that?

[timunie]

Sure

<DataGrid Items="{Binding MyItems}">
    <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Title}"
                            ClipboardContentBinding="{Binding Title}"
                            Header="Title"  />
          [ ... ]
    </DataGrid.Columns>
</DataGrid>
