Hi,

I have an error with the previewer. Code works fine but have no preview available.

Here is the code :

<Window xmlns="http://schemas.alternetsoft.com/ui/2021"
        xmlns:x="http://schemas.alternetsoft.com/ui/2021/uixml"
        x:Class="Mig2AlternetUI.MainWindow"
        Title="Mig2AlternetUI"
		Width="400" Height="600">
	<StackPanel Orientation="Vertical" Padding="10" Grid.Column="0">
		<Label Text="C# Project Path :" />
		<TextBox Text="Enter Project path" Name="txtboxPath" Margin="0,0,50,0" TextChanged="txtboxPath_TextChanged" MouseLeftButtonDown="txtboxPath_Click"/>
		<Button Text="..." Name="btnPath" Margin="318,-23,0,0" Width="10" Click="btnPath_Click"/>
		<Button Text="Create Report" Name="btnReport" Click="btnReport_Click"/>
		<TextBox Text="" Name="txtboxDebug" Height="445" Multiline="True"/>
		<Label Text="" Name="lblResult" Margin="4"/>
		<Label Text="" Name="lblOutput" Margin="4,0,0,0"/>
	</StackPanel>
</Window>

Here is error :

Error come from "MouseLeftButtonDown" semms to be not "understand" by previewer.

Thank you for your help.

Hi,

Can you tell me if you reproduce this error and if you have a solution or an approximate date to correct this ?

Thanks.

Hi NeoXeo,

We reproduced this problem when editing this UIXML, and it seems to be related to the MouseLeftButtonDown event handler. If you define the event handler itself like this, the preview seems to work correctly. We will try to fix this issue very shortly.

    private void TxtboxPath_MouseLeftButtonDown(object sender, Alternet.UI.MouseButtonEventArgs e)
    {
        
    }

Kind regards,
Dmitry

I have updated issue on AlterNet UI GitHub repository with version 0.9.153. Error still present and solution to declare event handler into code doesn’t work.
Thank for your help.
