Unable to find suitable setter or adder for property Click

I’m unable to set “Click” event for Button in XAML. Adding “Click” attribute in XAML throws error during compilation (no matter if method exist or not in cs file): “Avalonia error XAMLIL: Unable to find suitable setter or adder for property Click of type Avalonia.Controls:Avalonia.Controls.Button for argument System.Runtime:System.String, available setter parameter lists are:”

Here is MainWindow.xaml:

<Window xmlns="https://github.com/avaloniaui"
        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"
        mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
        x:Class="MMHelper.MainWindow"
        Title="MMHelper">
    <Button Click="testClick" Content="Test" />
</Window>

I’ve looked into issues and found similar issue but I seems it was fixed. I’m using .Net Core 3.1 on Arch Linux, Avalonia version is 0.9.2.

Hi. I have similar problem. I am trying to add event SelectionChanged to drop box, but I get this error. Also getting same error with PointerPressed event in data grid, but LoadingRow works. So theese are events from documentation. Am I missing something? I’m using Avalonia 0.10.14 on Windows and .NET6.

<ComboBox Name="ComboBox" Width="100" Height="28" Margin="15,21,0,0" Items="{Binding SerialCards}" SelectedItem="{Binding Path=SelectedCard, Mode=TwoWay}" SelectionChanged="_DropDownClosed"/>

<DataGrid MaxHeight="300" Name="InvoicesGrid" Items="{Binding SdcImportedInvoices}" AutoGenerateColumns="False" LoadingRow="dataGrid_LoadingRows" IsReadOnly="True" PointerPressed="_OnRowClick">

Hello… I had similar problem, also, and I resolved it on a way that I’m used propper parameter in a given event method. For example, if we want use GotFocus we can use method such as:

`private void Handler(object sender, GotFocusEventArgs e)
        {
            
        }`

If we want use LostFocus we can use it such as:

`private void Handler2(object sender, RoutedEventArgs e)
        {
            
        }`

If we want use TextInput event we can use it such as:

`private void Handler3(object sender, TextInputEventArgs e)
        {
            
        }`

Where Handler, Handler2 and Handler3 are names of given event from xaml. You can see documentation, for example for textbox control: http://reference.avaloniaui.net/api/Avalonia.Controls/TextBox/
