How to custom hc:MessageBox global?

[GF-Huang]

Hi, @ghost1372
I want to set it BorderThinkness to 0. I had read this https://hosseini.ninja/handycontrol/extend_controls/messageBox/, but I don't like show message with MessageBoxInfo every time. Is it a global way to custom it?

And why the hc:MessageBox does not show in the completion list?

Second best, even if I write as the docs, my XAML designer will crash.

Mini project to duplicate this issue. MessageBoxDemo.zip

you should overwrite messagebox style
It is definitely due to the weakness of the vs designer. There is no problem in runtime and the style is chosen correctly

🤔 I think you can inherit from control you want and in the Ctor check if DesignTime is true or not and if true return it.

public myControl()
{
if (DesignerProperties.GetIsInDesignMode(this))
{
return;
}
}

What differences if return or not?

[ghost1372]

Well, if it return, it will not be rendered in design mode, but if it is not returned, the control will be rendered.
Return means that you no longer need to initialize the control and its codes

Oh, you lost the InitializeComponent() call.
