I'm new to C# I was wondering

When the user logins (in form1, using only their username and password), form2 should display the users employee ID number. Is this possible?

private void LginBtn_Click(object sender, EventArgs e)
{
    string query = "Select * from Employees Where [Employee Username] = '" + Username_txt.Text + "' and [Employee Password] = '" + Password_txt.Text + "'";
    OleDbDataAdapter sda = new OleDbDataAdapter(query, MAcon);

    DataTable dtbl = new DataTable();
    sda.Fill(dtbl);

    //TO-DO:Check login username & Password
    if (dtbl.Rows.Count == 1)
    {
    this.Hide();
    Dashboard main = new Dashboard();
    main.Show();

    }

What I have tried:

private void LginBtn_Click(object sender, EventArgs e)
{
    string query = "Select * from Employees Where [Employee Username] = '" + Username_txt.Text + "' and [Employee Password] = '" + Password_txt.Text + "'";
    OleDbDataAdapter sda = new OleDbDataAdapter(query, MAcon);

    DataTable dtbl = new DataTable();
    sda.Fill(dtbl);

    //TO-DO:Check login username & Password
    if (dtbl.Rows.Count == 1)
    {
    this.Hide();
    Dashboard main = new Dashboard();
    main.Show();

    }

This is very possible. I'm assuming DashBoard is your "form2"? If so create property in your Dashboard form2 class called

public string EmployeeID {get;set;}

Then do

Dashboard main = new Dashboard();
main.EmployeeID = dtbl.Rows[0]["EmployeeID"];
main.Show();

Replace "EmployeeID" with whatever the actual field name is in your data table.
this is a rough pseudo code, so it may not be syntactically precise, but its close.

You could also create a property of

public DataTable Employee{get;set;}

and pass the whole datatable if you want and access its info on your dashboard form.
However you want.

Many possibilities.
