    I would need the possibility to change the font (colors and attributes) of each Tab seperately as seen in a screenshot of an older app. An easy try with easy html in the .text propert doesnt seem to work.

    Is there an easy way to achieve this?

    Thank you.

    Is this possible with a “themed” docking tab?

    Hi Andreas,

    actually, there are properties “C1DockingTabPage.TabBackColor / TabBackColorSelected / TabForeColor / TabForeColorSelected” to change the colors. But it seems they are ignored when using a VisualStyle (here, only the “…Selected” properties work) or a C1Theme (don’t work at all).

    C1, could you take a look at this? We use custom back/fore colors, too, and I just noticed that this went broken…

    There is no simple way to change the font . You could owner draw the tab area by handling the event “C1DockingTab.DrawTab” => but here, you would have to take care for drawing all the tab area, including borders and selection, which will probably not result in the same layout that C1 provides :-).

    The api for rendering (namespace “C1.Win.C1Command.Docking.Drawing”) is private API, otherwise you might e.g. subclass one of the renderers and provide custom colors for certain items.

    Best regards

    Hello,

    Thank you, Wolfgang.

    Andreas, as per our observations (with Build Version 4.0.20181.307), the TabForeColor, TabForeColorSelected, TabBackColor, TabBackColorSelected properties related to C1DockingTabPage work fine even when the VisualStyles are set. However, when a theme is applied, the tabpages seem to lose the formatting based on these properties. We have reported this issue to the concerned team [Internal Tracking ID: 327692] and will get back to you once we hear from them.

    Also, we are discussing if the other font related attributes can be set for the tab page’s text.

    Best Regards,

    Esha

    I will examine what happens if I first set the theme , then set it to “nothing” 4 the control and then set the mentioned TabBackColor etc. properties… (that s my hope :slight_smile: ) … I ll report

    In the meantime … mobile greets and thanx

    Hello,

    Which old apps are you referring to? Do you mind sharing one here?

    Seems like you are talking about MS TabControl. “C1DockingTab.DrawTab” is the drawing related event corresponding to C1DockingTab.

    Thanks,

    Hi Esha,

    the BackColor does not work when a VisualStyle is set, see attached sample (using .307): tab 2 should have a yellow background, but it is only shown when the mouse is hovering over it. I expect it to be yellow always.

    Best regards

    The “old” app I have to re-program (to add some new features) is a c and win32api app. you can see a small screenshot in my first post. The tabheaders in that old app were ownerdrawn. However I have come over with the customer that we will use a certain theme and the tab control will not be themed but its colors will be set to the themecolors, so I can set the tabheaders to other colors if needed. This is more important than that the app is themable for the users.

    If there is a solution from C1 this however would be nice …

    Thank you.
