primary your personal sended code nobody see then nobody help.

volatile uint8_t count = 0;
			HAL_GPIO_TogglePin(GPIOB, Red_Led_Pin);
			HAL_Delay(100);

For ISR variables need volatile. Your count++ and if else is litle complicated. 

And your code isnt timer interrupt in GPIO. You only start timer with IT method aplied...

HAL_TIM_Base_Start_IT(&htim3);

And use Delay in callback is mistake if systick isnt higher priority code hang here

If I press the user button for 2 sec.  Then red led will tern on .... Again I press button then red led will tern off.....If I continue press the button led will be tern off........ 

I did some changes but my problem is not solved ...

Dude, tell the people what you want to achieve.

Even your starting post "How to use timer interrupt in GPIO interrupt" is ridiculous, we have no time for guessing.

Extremely  Sorry ... next time definitely I will try
