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);
