Question

How can I get a value returned from the checkbox_CheckChanged event please? Its a winforms app, and both the form and the checkbox are created programmatically. Thanks for all and any help.

Answer 1

The Controls event handlers are always “void” and you cant change the return type. Instead you can take an external variable and you change that value only in when the CheckedChanged Event occurs.

public bool checkedthecheckbox { get; set; }

CheckBox testchbox = new CheckBox();

private void Form1_Load(object sender, EventArgs e)
{
    testchbox.CheckedChanged += new EventHandler(testchbox_CheckedChanged);
}

void testchbox_CheckedChanged(object sender, EventArgs e)
{
    if (testchbox.Checked)
        checkedthecheckbox = true;
    else
        checkedthecheckbox = false;
}
