Cursor Not Changing on GridSplitter - Community Toolkit

Question

Trying out the Community Toolkit GridSplitter, but the cursor does not change when I hover over the splitter bar. Changing the GripperCursor or CursorBehavior properties has no effect. It stays with the default cursor.

It resizes the panes when clicked and dragged, but the mouse cursor does not behave as expected.

I am using packages WindowsAppSDK 1.3.2305,
CommunityToolkit.WinUI.UI 7.1.2 and CommunityToolkit.WinUI.UI.Controls.Layout 7.1.2

I'm not sure but I guess the cursor of the GridSplitter doesn't work on WinUI 3 apps.

You should try the GridSplitter from the CommunityToolkit.Labs.WinUI.SizerBase NuGet package. I can confirm that its cursor works.

1. Add a new NuGet package source.

   Feed URL: https://pkgs.dev.azure.com/dotnet/CommunityToolkit/_packaging/CommunityToolkit-Labs/nuget/v3/index.json

2. Temporarily, disable other package sources, including nuget.org. I don't know why but I couldn't install the CommunityToolkit.Labs.WinUI.SizerBase with other sources enabled.

3. Enable Include prerelease.

4. Add the CommunityToolkit.Labs.WinUI.SizerBase package.

And use it like this:

            <RowDefinition MinHeight="100" />
        </Grid.RowDefinitions>

        <Grid Grid.Row="0">
            <TextBlock
                Margin="10,10,0,0"
                Text="Top Row." />
        </Grid>

        <controls:GridSplitter
            Grid.Row="1"
            Cursor="UniversalNo" />

        <Grid Grid.Row="2">
            <TextBlock Text="Bottom Row." />
        </Grid>
    </Grid>
