Passing of a dynamic checked box to another box.

Hi, I am new to this. i would like to pass over checked values from form1 to form2 however i am currently using the dynamic checkbox, thus the output i would like use for another sql query in form2.

Here is my code:

private void populateSalesCategory()
{
con.Connect();
string selectQuery = "SELECT * FROM SalesCategory";
using (SqlDataAdapter sda = new SqlDataAdapter(selectQuery, con.conn))
{
//Fill the DataTable with records from table
DataTable scdt = new DataTable();
sda.Fill(scdt);
//Loop and add CheckBoxes to SalesCategoryPanel.
string sc = "";
foreach (DataRow row in scdt.Rows)
{
CheckBox chk = new CheckBox();
chk.Width = 100;
chk.Text = row["CategoryName"].ToString();
chk.CheckedChanged += new EventHandler(changecheck);
salesCategoryPanel.Controls.Add(chk);
}
}
}
private void changecheck(object sender, EventArgs e)
{
CheckBox chk = sender as CheckBox;
if (chk.Checked)
{
MessageBox.Show(chk.Text);
}
}

Thanks a lot.
