events

Question

I have a method

 

public void mybutton_click(object sender ,eventArgs e){

 textblock.text=1;

}

public String mymethod(){

if(textlock.text==1){

return "mixture ";

}

else {

return  "fixed";

}

}

problem is when i try to return  the values from mymethod to  a timer event  I get the error

Not all code paths return a value  .

how do i resolve so as to return a value from mymethod
