Simply you can declare a flag variable and set the flag to different values .
ie
1 for button1
2 for button2

you need to compare the value and display the group of controls accordingly in the target form.

Here is how I would handle this.

On Form1 in button1_Click put the following

 Form2 frm2 = new Form2();

frm2.iMode = 1;
frm2.Show();

In button2_Click put the following

           Form2 frm2 = new Form2();
     
frm2.iMode = 2;
frm2.Show();

In Form2 put the following

    public partial class Form2 : Form
    {
        [B]public int iMode = 0;[/B]
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_Load(object sender, EventArgs e)
        {
 [B]       if (iMode == 0)
            {
                //No value was passed... don't show the form
                MessageBox.Show("Mode value not set");
                this.Close();
            }
            else if (iMode == 1)
            {
                //Show some controls
            }
            else if (iMode == 2)
            {
                //Show some other controls
            }[/B]      
       }
    }

All your doing is setting the iMode value for Form2 depending on which button is pushed. So, if button1 is pushed then the iMode is set to 1 and if button2 is pushed then iMode is set to 2 and if iMode is not set then its defaults to 0 and Form2 will not show. I hope this helps

That's a great example Torgg.
Thanks a lot!

I just wanted to add to Torgg's recommendation by reminding you that you have the Object sender, and EventArgs e variables at your disposal to. You can use the Object sender parameter to determine what object triggered the event.

Could you give me an example of what you mean? Maybe based on the sample above.

This strikes me more as a job for the constructor to me than a job for the Form load event.
Just pass a different parameter to the constructor of Form2 depending on which button was clicked in Form1.
