Enable and Disable buttons, labels based on some conditions

Question

I have 5 buttons and 5 labels next to each button. When i run the app i expect the first button to be enabled and the the rest disabled and greyed out with the labels. after i click the first button it should disable with the label and enable the second button, and so forth with all the other buttons.

this way is to long, is there a better way of doing this?

private void Form1_Load(object sender, EventArgs e) { btn1.Enabled = true; btn2.Enabled = false; btn3.Enabled = false; btn4.Enabled = false; btn5.Enabled = false; lblStep1.Enabled = true; lblStep2.Enabled = false; lblStep3.Enabled = false; lblStep4.Enabled = false; lblStep5.Enabled = false; } private void btn1_Click(object sender, EventArgs e) { btn1.Enabled = false; btn2.Enabled = true; btn3.Enabled = false; btn4.Enabled = false; btn5.Enabled = false; lblStep1.Enabled = false; lblStep2.Enabled = true; lblStep3.Enabled = false; lblStep4.Enabled = false; lblStep5.Enabled = false; } private void btn2_Click(object sender, EventArgs e) { btn1.Enabled = false; btn2.Enabled = false; btn3.Enabled = true; btn4.Enabled = false; btn5.Enabled = false; lblStep1.Enabled = false; lblStep2.Enabled = false; lblStep3.Enabled = true; lblStep4.Enabled = false; lblStep5.Enabled = false; } } private void btn3_Click(object sender, EventArgs e) { btn1.Enabled = false; btn2.Enabled = false; btn3.Enabled = false; btn4.Enabled = true; btn5.Enabled = false; lblStep1.Enabled = false; lblStep2.Enabled = false; lblStep3.Enabled = false; lblStep4.Enabled = true; lblStep5.Enabled = false; } private void btn4_Click(object sender, EventArgs e) { btn1.Enabled = false; btn2.Enabled = false; btn3.Enabled = false; btn4.Enabled = false; btn5.Enabled = true; lblStep1.Enabled = false; lblStep2.Enabled = false; lblStep3.Enabled = false; lblStep4.Enabled = false; lblStep5.Enabled = true; } private void btn5_Click(object sender, EventArgs e) { btn1.Enabled = true; btn2.Enabled = false; btn3.Enabled = false; btn4.Enabled = false; btn5.Enabled = false; lblStep1.Enabled = true; lblStep2.Enabled = false; lblStep3.Enabled = false; lblStep4.Enabled = false; lblStep5.Enabled = false; }

Create a bool method or just method. Then slap that err.. call the method on each button to somehow shorten the code. — P. Pat

If the controls are related in logic there should be some data structure(eg. List<Button>) to reflect this. — Lei Yang

Let all these buttons and labels are inside a container(if it doesn't mean that you can use this.Controls as well if the form contains these buttons and labels only). Let it be pnlContainer, Now you can try something like this:

public void ButtonController(Button buttonToEnable, Label labelToenable) { foreach (Control ctrl in panel1.Controls) { if (ctrl == buttonToEnable || ctrl == labelToenable) { ctrl.Enabled = true; } else { ctrl.Enabled = false; } } }

So in Form1_Load you want to enable btn1 and lblStep1 so the call should be :

ButtonController(btn1,lblStep1);

For btn1_Click the method call will be like ButtonController(btn2,lblStep2);. in short, you can pass the button and label that you want to enable to this method, which will disable rest of controls in the container.
