What I perceive from above description is that, you need to get values in Main Form (Form1) TextBox(s) controls on the Selection of row in a DataGridView in Sub-Form(Form2). If it is like that, then you just need to write some code in Selection_Changed event of Sub-Form(Form2) DataGridView and Assign the Selected Row Cells Value to TextBox Controls in MainForm. (If you need help in code then please mention your code, so I can figure out what is missing).

If form2 known in from1:

C#

public partial class Form1 : Form
{
    Form2 form2;
    public Form1()
    {
        InitializeComponent();

        dataGridView1.Rows.Add(new object[] { "A1", "A2" });
        dataGridView1.Rows.Add(new object[] { "B1", "B2" });
        dataGridView1.Rows.Add(new object[] { "C1", "C2" });
    }

    private void dataGridView1_CurrentCellChanged(object sender, EventArgs e)
    {
        if (null != dataGridView1.CurrentRow)
            form2.ShowDataGridViewRow(dataGridView1.CurrentRow);
    }

    private void Form1_Shown(object sender, EventArgs e)
    {
        form2 = new Form2();
        form2.Show();
    }
}

C#

public partial class Form2 : Form
{
    public Form2()
    {
        InitializeComponent();
    }

    internal void ShowDataGridViewRow(DataGridViewRow dataGridViewRow)
    {
        label1.Text = dataGridViewRow.Cells[0].Value.ToString();
        label2.Text = dataGridViewRow.Cells[1].Value.ToString();
    }
}

the rest should be obvious ...

You need to write that code in dataGridView1_SelectionChanged Event instead of dataGridView1_CellClick Event. And use this object

FrmUsers fpc = new FrmUsers();

instead of creating new object in event handler.

Its Very Simple Your method will not work because you make object of form1 each object has its own memory...So it will defiantly not going to be work so for that..
Make one static variable name Id (If u have id in table 'login')
or you can use whatever field you may like to use instead of id
In form1...

C#

public static Int32 UserID;

private void btnsearch_Click(object sender, EventArgs e) 
{ 
Form2 f2 = new Form2(); 
fr2.ShowDialog();

if (UserID != 0)
{
//Fill The TextBox Using The UserID
....
//Set UserID again to 0
               
UserID= 0;

}

}

in Form2 at click event..

C#

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) 
{ 
//just set UserID because it is staic we can easily give it value

Form1.UserID = 12;//Give your value for UserID

this.close();
}

Or Use can make more static variables each for user-password,user-role and so on...but i will not suggest that method...Use Above method it is easiest way...Gud Luck
