Two Forms and Controls Interaction

Memento

On the Form1 I have two buttons.
Both buttons load Form2, but:
- when loaded by the btn1, dgv(on the Form2) should have ds1 as DataSource.
- when loaded by the btn2, dgv(on the Form2) should have ds2 as DataSource.

Also - Fom2_Closing Event should run this:
Form1.Text = "323";
Form1.btn1.Visible = false;

Problem in my tryings is properly establishing the relations between forms..
Could somebody help, please?

//pass string to method - you said !

Frog,
Is it the truth that the same brain invented the Chess and C# ?

ThanksMan !

This site is a real treasure.
Huge difference comparing to other "helping" pages.
One day, I hope, I could give you money, instead clicking on (is there maybe a maximum clicks, without breaking some rule?)
Is there a rellevant place where I could write my impressions (site's founder or similar)?

Both solutions are so different, and both - Works.

Just a question to Frog:
How about if I instead: Form1.Text = "323";
want: Form1.Text = Form2.dgv2.CurrentCell.Value.ToString();
I probably need to declare somewhere this string as public, and tried on both forms but got error - Index is out of Range....

And another way

In Form2, add some private fields and change the constructor as follows:

class Form2 : Form
{
private Form1 f1;

private DataSet ds;

public Form2(Form1 f1, DataSet ds)
{
InitializeComponent();
this.f1 = f1;
this.ds = ds;
dgv.DataSource = ds;
}

// other methods

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
f1.Text = "323";
f1.Controls["btn1"].Visible = false;
f1.f2 = null;
}
}

Now from Form1:

// add this field
internal Form2 f2;

private void btn1_Click(object sender, EventArgs e)
{
if (f2 == null)
{
f2 = new Form2(this, ds1);
f2.Show();
}
}

private void btn2_Click(object sender, EventArgs e)
{
if (f2 == null)
{
f2 = new Form2(this, ds2);
f2.Show();
}
}
