asked on

the use of DialogResult question.

Hi,
can you please explain the use of DialogResult in this code? I have two forms. Form1 opens Form2 as a modal dialog using a button. For that action, I used f2.ShowDialog(); when 'open' button is clicked on Form1.
Now, in Form2 when I click 'Save' button, the values in Form2 will be saved.

private void button1_Click(object sender, EventArgs e)
{
// Do somthing for saving result.
this.DialogResult = DialogResult.OK;
}

But, when I add the last line(this.DialogResult = DialogResult.OK; ), Form2 is closed. I don't understand the last line of code. I don't know how this line of code close Form2. What does 'DialogResult.OK' really mean in this code?

Hi muffintwinkly;

You can use this property to determine how a dialog box is closed in order to properly process the actions performed in the dialog box by the caller.

Form.DialogResult Property can be found here.

Possible values for DialogResult and there meaning can be found here

Setting the Form.DialogResult Property to anything other then DialogResult.None will hide the form after executing the command.

Thanks, it helped me alot already. But, I want to know what know is what 'DialogResult.Ok' means. I read MSDN, but still don't understand what 'The dialog box return value is OK ' means. - I know that this value is from Form2. but, does it mean 'Form2 is opened correctly?' or something else? I guee that 'this.DialogResult' means Form2's DialogResult. What is 'DialogResult.OK' and why do whe this value to Form2's DialogResult?
