How to check which button was pressed

[TBBW]

Hi all,

I have a Main Dialog it has 3 buttons; Install, Support and Exit
When the Install button is pressed a License Agreement Dialog is opened using .ShowDialog();
This Dialog has two buttons Install and Cancel.
(The Install button is enabled using two radio buttons (accept and do not accept))

But I use Close(); on both the Cancel and the Install button.
So back in the main menu I need to know if the Install button was presssed or if the cancel button was hit.
I can use a global int or bool flag, but that is not C# like.

How can this be done.

regards,

Gerwin

The License Agreement Dialog is made by you? If so, provide a public get-only property on your dialog class that would return an indicator of type DialogResult, and set it to either DialogResult.OK or DialogResult.Cancel from within the button handlers. Then you can check this property when the dialog is closed. Other dialogs available in the library use this method, and the property is usually called DialogResult itself - something like this:
DialogResult DialogResult { get; private set; }

Hi Great,

Thanks for the info I only inserted the following lines:

            DialogResult dr = new DialogResult();
            LicenseAgreement LA = new LicenseAgreement();
            dr = LA.ShowDialog();
            if (dr == DialogResult.OK)
                MessageBox.Show("User clicked OK button");
            else if (dr == DialogResult.Cancel)
                MessageBox.Show("User clicked Cancel button");

thanks!

I am not entirely sure I follow. However, I think DialogResult might be helpful: http://www.dotnetperls.com/dialogresult If so, great! If not, push back an we'll try to help you some more.

Hi

try this

in the form designer set the click event for both buttons to the same function; in this case 'button_Click'

this.button6.Location = new System.Drawing.Point(243, 85);
            this.button6.Name = "button6";
            this.button6.Size = new System.Drawing.Size(85, 29);
            this.button6.TabIndex = 6;
            this.button6.Text = "button6";
            this.button6.UseVisualStyleBackColor = true;
            this.button6.Click += new System.EventHandler(this.button_Click);
            // 
            // button7
            // 
            this.button7.Location = new System.Drawing.Point(342, 84);
            this.button7.Name = "button7";
            this.button7.Size = new System.Drawing.Size(79, 29);
            this.button7.TabIndex = 7;
            this.button7.Text = "button7";
            this.button7.UseVisualStyleBackColor = true;
            this.button7.Click += new System.EventHandler(this.button_Click);

then do this in the form

private void button_Click(object sender, EventArgs e)
        {
            if (sender == button6)
                MessageBox.Show (sender.ToString());
            else if ( sender == button7 )
                MessageBox.Show (sender.ToString());
 
        }

Hope this helps

This is probably a better way to test which object is the sender rather than ==

if (object.ReferenceEquals(sender, button6 ) )
MessageBox.Show (sender.ToString());
else if (object.ReferenceEquals(sender, button7 ) )
MessageBox.Show (sender.ToString());

Thanks for contributing, but that can't be done as the buttons which are raising the evens are encapsulated inside a different form (a dialog), so they are not accessible (and are out of scope, since the dialog is closed). Anyway, this is an accidental duplicate thread, the question has already been resolved here, using the DialogResult enumeration - as suggested by
BioPhysEngr in the post above (which is a standard way to get this kind of info from a dialog).

Thanks all for the replies,

First, for some strange reason there is a duplicate post, please do not reply to that one !!

As I mentioned in the parrallel post I only use these short snip

DialogResult dr = new DialogResult();
LicenseAgreement LA = new LicenseAgreement();
dr = LA.ShowDialog();
if (dr == DialogResult.OK)
     MessageBox.Show("User clicked OK button");
else 
     MessageBox.Show("User clicked Cancel button");

Works Super!!
awaiting your comments.
