Like i would do in winforms dialog

if(MessageBox.Show("Exit?", "Close UP", 
     MessageBoxButtons.YesNo)== DialogResult.Yes)

Any idea how i do so ?

Answer 1

You can use the DialogResult Property of the Button on your Dialog form and set it to DialogResult Enumeration like:

//in your dialog form
button1.DialogResult = DialogResult.OK;

then in your main form :

//Create an instance of your dialog form
Form2 testDialog = new Form2();

// Show testDialog as a modal dialog and determine if DialogResult = OK.
if (testDialog.ShowDialog(this) == DialogResult.OK)
{
   //do processing
}
else
{
   //do processing
}

Map the AcceptButton property on the Form to Set button in the designer.

Or in the Set button click handler you could set some value.

        private void HandleOnSetButtonClick(object sender, EventArgs e)
        {
            this.IsSetClicked = true;
            this.Close();

            //or 
            this.DialogResult = System.Windows.Forms.DialogResult.OK;
            this.Close();
        }   

        public Boolean IsSetClicked
        {
           get;
           private set;
        }
