Question

I have created a messagebox which returns DialogResult. Now I added checkbox on it and want to know if it is checked or not. So what should I return? The simple way I thought is to create new enum which will have all the values from DialogResult plus a value to indicate checkbox status

public enum MyDlgResult
{
    NONE = DialogResult.NONE, 
    OK = DialogResult.OK ........................, 
    CHKBOXCHECKED = 8
}

…and returning this enum MyDlgResult.
But is this correct approach? Because I have to add value in this enum every time a new functionality is added to my messagebox.
Better way to do this if any.
Thank You.

Answer 1

Just add Property to that message box, which will be a proxy to Checked property of CheckBox and on OK result form message box check that new Property.

Property to add

public bool Checked
{
   get { return yourCheckBox.Checked; }
}

And final code like this

MessBox box = new MessBox();
if(box.Show() == DialogResult.OK)
{
   bool isChecked = box.Checked;
}
