It is one that are included with netadvantage suite

here is the method that i use :

 Public Function LoadStyleTemplate(ByVal aTheme As PStyleTemplate) As Boolean

            Dim themePath As New StringBuilder

            themePath.Append(Application.StartupPath).Append("\Assets\Styles\").Append(aTheme.Path)

            If themePath IsNot Nothing AndAlso File.Exists(themePath.ToString) Then

                AppStyling.StyleManager.Load(themePath.ToString)

                InfoSession.SelectedTheme = aTheme


                Return True

            Else
                Return False
            End If

        End Function

I know this is an old topic but I'm also having the same freezing issue with our application. I did recently open a ticket regarding this, as I only had the issue locally on my dev machine, however now we've had clients report the issue as we sent out an update to the application.

I'm using v16.2.20162.2111 of Infragistics WIN FORMS - so quite a few versions later than the original poster. When the application first loads I load in the theme, then a login form is displayed for the user, when the user logs in, it will then load the theme that the user has selected previously (filename saved in db), if no theme selected, then it will load our default theme again. As we don't supply any other themes to the user at the moment, it's always the default one.

Q) Can I pull the filename out of the stylemanager after it's loaded then maybe I don't need to load again if it's the same file???

I can't replicate this on a small demo app at all, and only had it locally a couple of times - mostly when running from VS2017 - when I break the code after it's hung it breaks on the line:

StyleManager.Load(themeFile.FullName);

and won't continue on.

The clients we have that are reporting the issue seem to be on larger environments, and some on terminal servers running the same application, and possibly accessing the same file.

Is there anything in the Stylemanager code that could cause this hang??? I'm at a loss on what I can do at my end.

Thanks

Having the same issue here:

Infragistics.Win.AppStyling.StyleManager.Load(@"styles\black.isl");

Using version 18.1.20181.88

Completely freezes the application..no exception nothing. 

Did you get an answer on this?

Thanks,
