[CLOSED] MaskConfig with icon

[bbros]

Hi, I would like to place an icon in the MaskConfig
I think I have to work on MsgCls property but I don't know which class I have to manage.
I would like to fill the white in which I put a green spot in the following image


It is enough the loader icon, or a custom one.

My code is

Ext.Net.X.Mask.Show(New MaskConfig With {.Msg = GetText("TryAuthenticationWelcome") & " " & username})
Ext.Net.X.Redirect(HttpContext.Current.Request.Url.AbsoluteUri)

Is it possible?

Thank you.
