无法使用 Windows 社区工具包中的 GridView 控件

Question

I'm having a problem getting the GridView control from the Windows Community Toolkit working in my WinUI project. I've added the Microsoft.Toolkit.Uwp.UI.Control nuget package, which has installed successfully, and I can see it added to the correct project in solution explorer.

My XAML (some irrelevant code removed for brevity) is as follows:

<Window
    x:Class="SampleApp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" SizeChanged="SizeChanged"
    mc:Ignorable="d">
        (other controls/content removed for brevity)
        <controls:DataGrid (code removed for brevity)>
        </controls:DataGrid>
</Window>

When trying to add the control to the XAML file, the line xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls" gives the compiler error:

XLS0429 Undefined namespace. The 'using' URI refers to a namespace 'Microsoft.Toolkit.Uwp.UI.Controls' that could not be found.

...and the line starting <controls:DataGrid gives the compiler error:

XLS0414 The type 'controls:DataGrid' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

I've been following examples such as this one , but I'm not getting anywhere.

Can anyone point me in the right direction?

Answer 1

You've used the tag 'winui-3' yet your package is for UWP / WinUI 2.

Pick one and try again.
