[jinyistudio]

Hi, I use UpdateTopbarItem to showing time. But Could i how to chage its size and color ?

Sub timer1_Tick
    Timer1.Interval=1000   
    Dim comp As ABMContainer = page.NavigationBar.SideBarTopComponent   
    DateTime.TimeFormat="HH:mm:ss"
    page.NavigationBar.UseTheme("topTime")
    page.NavigationBar.UpdateTopbarItem("datetime","",DateTime.Time(DateTime.Now))
End Sub

I think you can do it using the theme settings...
Almost every component has a forecolor, forecolor tensity, backgroundcolor and backgroundcolorintensity

I have try page.NavigationBar.UseTheme("topTime") but it is invalid.

Have you created the theme in the buildTheme or in ABMShared?
My theme.AddTopNavigationBar("topTime")
MyTheme.TopNavigationBar("topTime").ForeColor = ....

This is to be considered as pseudo-code as I am not at my pc to be sure of it

My version 2.51 has AddNavigationBarTheme. It hasn't AddNavigationBarTheme

my code as

theme.AddNavigationBarTheme("topTime")
    theme.NavigationBar("topTime").TopBarBold = True
    theme.NavigationBar("topTime").TopBarFontSize = "18px"
    theme.NavigationBar("topTime").TopBarForeColor=ABM.COLOR_RED

Try setting page.NavigationBar.UseTheme("topTime") not in the timer, but in the ConnectPage().
UpdateTopbarItem() can not change the color at run time.
