When checkbox is checked as true, it is calling the checkedChanged event handler.

C#

this.signedChkBx.Checked = true;

If it is checked as false it is not calling the checkedChanged event handler.

C#

this.signedChkBx.Checked = false;

My CheckedChanged event handler is

C#

private void signedChkBx_CheckedChanged(object sender, EventArgs e)
        {
            if (this.signedChkBx.Checked == false)
            {
                ChangedSettings.changedReason = 0;
            } // if
            else
            {
                ChangedSettings.changedSignedBy = 1;
            } // else
        }

What can the reason be for not calling in case of false?

It will depend on order of these lines of code. If on form load, you are setting checked as false, that is not a check change since by default the check box is unchecked. Can you update your question with some more code? Where are you setting this as false and how are you binding event handler?

Hmm, Strange. Code looks good.
Can you try using debugger ? Or you might want to change the order of your change event.

Is there any javascript code is injected for the checkbox. Please recheck.

If CheckedChanged handler isnt working, you can try these 3 things:

1). Create your own bool method like, isChecked(checkBox1):

Code:

C#

public bool isChecked(CheckBox checkbox){
  if (checkbox.CheckState == CheckState.Checked) return true;
  else return false;
}

Example:

C#

if (isChecked(checkBox1)) {
  MessageBox.Show("Checked");
} else {
  MessageBox.Show("Not Checked");
}

2). Try using CheckStateChanged Handler.
3). Clean build the project.

I recommend the first one :) .
