Apply custom theme in code

Hi

I have made a few custom themes using the theme editor.  They work properly when I apply them using the following code:

Me.calendar.CustomTheme = White1

where White1 is the name of the theme based on white.dll.

I want to give users the option to set a default theme and then apply the theme based on a value returned from an sql table but I'm not sure how to proceed.  For instance, something like the following:

If dr.Read Then
Me.calendar.Theme = drUser("colourScheme")

Thanks for any help...

You can do that by saving the full type name of the theme into the database. Then, when reading the theme type, you can create a new Theme object using that type and assign it to the Calendar.CustomTheme property.

The following code illustrates this. The assembly variable identifies the assembly containing your custom themes and myThemeType is a string variable containing the full type name of the theme you want to load:

Code
Select All
calendar1.CustomTheme = CType(assembly.GetType(myThemeType).GetConstructor(Type.EmptyTypes).Invoke(Nothing), MindFusion.Scheduling.WinForms.Theme)

You can put the appropriate checks to ensure that the theme loads successfully.

Hi Meppy

I think my brain isn't working right today; I'm having trouble getting this to work...

The dll I'm using is named white.dll in a namespace called BrianThemes but I'm not sure how to create a variable to identify the assembly.

Do you have any further suggestions? Thanks a lot...

I am using the Assembly.LoadFile method for this purpose. You can also use the Assembly.Load and Assembly.GetAssembly depending on where your assembly is located.

Cool; got it using the following:

Dim a As System.Reflection.Assembly
                   a = System.Reflection.Assembly.LoadFile("\\Sbdb5\db_development\calendarTest\customT
hemes\white.dll")
                   Me.calendar.CustomTheme = CType(a.GetType(Me.White1.GetType.FullName.ToString()).GetConstructor(Type.Empty
Types).Invoke(Nothing), MindFusion.Scheduling.WinForms.Theme)

Thank you
