Hello Frank,

I wanted to know if you were able to solve your issue based on these suggestions or you still need help. Please let me know.

Hi Boris

No, I was not able to solve the problem.
Because the Appearance will be set at runtime,
I cannot use a Image, I dont know the BackColor.

Regards
Frank Uray

Hello Frank,

If you at least know what your backcolor is at runtime the only option I could think of would be to use a drawfilter for this, to draw a straight line with the width of the tab header and the desired color.

Hello Frank,

I am checking about the progress of this issue. Please let me know If you need any further assistance on this.

Hi Boris

Would it be possible for you the make a little sample
because I am a bit lost with this. At runtime, I know all the colors.

I have two additional questions to this:
How can I change the height of the Tab Header ?
As you can see in the attached picture, when a tab is selected
there is a little dotted border arround the text. How can I
switch this off ?

Thanks a lot and best regards
Frank Uray

Finally I did it but still 1 problem.

when i click the currently selected tab then the border location and width changes. so that i disable the selected tab which works fine.

But when focus is removed from the form and when again when focus is given to the form, border width changes in top tab and, border disappear in others tab.

I can't get, Why this happens?? 

(I used vertical/left tab orientation )

hello,

I'm also facing exactly same problem.

1) remove dotted rectangle 

2) border on left side of the selected tab header. (tab orientation is verticle)

I'm not getting the idea of above class. how to implement that??

Thanks in advance.

Hello Frank,

Yes, the values will depend on your exact scenario and control settings. I am glad to hear that you were able to solve this!

Please feel free to let me know if a question about our tool set comes up on your mind.

drawParams.Element.Offset(0, 0); works. :-)

Thanks and best regards

Hello Frank,

Could you please try to add the following line of code:

     drawParams.Element.Offset(0, -4);

Between the two lines in the else clause, so it goes like this:

                        drawParams.Element.Rect = new System.Drawing.Rectangle(drawParams.Element.Rect.Location, new System.Drawing.Size(drawParams.Element.Rect.Width, 5));
                        drawParams.Element.Offset(0, -4);
                        drawParams.Graphics.FillRectangle(new System.Drawing.SolidBrush(private_LineColor), drawParams.Element.Rect);
