从Form2返回数据时，如何检索表单1的其他值？

Question

Code of form1 ,

Picklist f2 = new Picklist(Query, this.Text);
f2.Show();

Code of form2 ,

DataGridViewRow Row = dgvPicklist.Rows[index];
this.Hide();
ItemMaster f2 = new ItemMaster(Row);
f2.Show();

Answer 1

Okay, to send values from form1 to form2:

In form1:

form2 F = new form2(something);  // something is the value you need to send
F.show();

In form2:

public form2(string x)  //Considering the type of your value is string, you can replace that with the required data type.
{
    string something = x;  //sets the value of x to something. Just like it was in form1.
    InitializeComponent();
}

I have considered the datatype of the value you wanted to transfer as string .

You could change it as required.

Answer 2

Use ShowModal() Instead of Show() :

 Picklist f2 = new Picklist(Query, this.Text);
 f2.ShowModal();
 string valueFromForm1 = TextBox1.Text;

ShowModal() waits till the opened form closes, and then executes the rest of the code
