I am using using TitleBar on windows form which is having minimize, maximize and close buttons but while I click on the maximize button the button image needs to be changed, attaching the the title bar maximize button image refer image TitleBarMaximize.PNG
I want to change the maximize button images
1. When the window is in maximized state show like in the image ExcelMaximized.PNG and
2. When the window is in resize state show like in the image ExcelResize.PNG
Currently the application is showing having only one button image as like in TitleBarMaximize.PNG in both resize state and maximized state.
How do I change the button image in title bar according to the above.
Any Immediate help will be much appreciated.
