# Working with Radio Buttons

I have a [program](https://www.mindstick.com/blog/12337/scaling-up-your-mentorship-program) which executes a code in 2 different ways based on the [radio button](https://www.mindstick.com/articles/12743/radio-button-in-android) selected(user's choice). My [problem](https://yourviews.mindstick.com/view/81399/tackling-the-problem-of-unemployment-during-corona-pandemic) is am not able to get what user has selected, meaning the code where it is suppose to [execute](https://www.mindstick.com/interview/49/how-can-i-execute-a-php-script-using-command-line) in different ways based on the radio button [selection](https://www.mindstick.com/blog/60/populate-records-in-second-listbox-according-to-the-selection-in-first-list-box) , that code [segment](https://www.mindstick.com/interview/1910/explain-the-difference-between-a-data-block-an-extent-and-a-segment) does not execute.

Here is what i have done :-

This is the part where i determine what user has selected from the radio buttons

public Airplane_Simulation()

{

InitializeComponent();

if (rbZero.Checked==true) //checks whether it is selected

{

[section](https://yourviews.mindstick.com/view/297/reservation-for-economically-weaker-section) = rbZero.Text; //if true assigns it's text to a [variable](https://www.mindstick.com/articles/1807/objective-c-data-types-variables-object-creation).

}

else

if (rbOne.Checked == true)

{

section = rbOne.Text;

}

[semaphore](https://www.mindstick.com/interview/1509/difference-between-critical-section-mutex-and-semaphore) = new Semaphore();

buff = new Buffer();

btnPnlT1 = new ButtonPanelThread(new Point(40, 5), 50, pnlArrival, false, Color.Red, semaphore, buff, btnGo);

waitingTakeOff = new waitPanels(new Point(490, 5), 50, pnlTakeOff, false, Color.Green, semaphore, buff,section);

thread1 = new Thread(new ThreadStart(btnPnlT1.start));

thread3 = new Thread(new ThreadStart(waitingTakeOff.start));

thread1.Start();

thread3.Start();

}

This is the code which is supposed to execute based on the user choice

if(section.Equals("0")) //if the variable match 0 it should this code

{

for (int k = 0; k < 15; k++)

{

panel.Invalidate();

this.movePlane(xDelta, yDelta);

[Thread.Sleep](https://www.mindstick.com/forum/161218/what-is-the-role-of-thread-sleep-in-multithreading-and-when-should-it-be-avoided)(delay);

}

}

else

if (section.Equals("1")) //if variable matches 1 it

//should execute this code

{

for (int k = 0; k < 40; k++)

{

panel.Invalidate();

this.movePlane(xDelta, yDelta);

Thread.Sleep(delay);

}

I tried assigning the value directly to variable section without taking from a radio button then it worked. So i am sure it's something to do with assigning when using radio buttons.

Thank you for your time.

Hi Royce,

Your only checking which one is selected when your form first opens, the user doesn't get chance to choose one, you need to create a selection changed event

By the way, else if on two lines is probably creating a nested if statement instead of an else if or else.

One way you can do this is,

public Airplane_Simulation()

{

InitializeComponent();

CheckedChanged();

rbZero.CheckedChanged += (s,e) => { CheckedChanged(); }

rbOne.CheckedChanged += (s,e) => { CheckedChanged(); }

public void CheckedChanged()

{

section = rbZero.Checked ? rbZero.Text : rbOne.Text;

}

Otherwise double click on a radio button in design mode.
