Access 2003 db
Field Name Data Type
CriminalOffence Text
VS 2010 C#
Using a groupbox, I can store data from radiobutton into my db. I have databinded both groupbox and radiobuttons to my db. When I use my nativgation buttons I see the data that has been stored where the groupbox text is. So the problem is I don't know how to properly retrieve data for the radiobutton. Retrieving data from textbox and combox is showing as it should be. Also when I want to insert new data the radiobutton does not get cleared. So...
I have two radiobuttons named, 1) rBYes 2) rBNo
I have the following method for inserting record...
private void btnInsert_Click(object sender, EventArgs e)
{
OleDbCommand cmd = new OleDbCommand(@"INSERT INTO Table1
(ID, AgeGroup, Gender, CriminalOffence)
VALUES(@txtID, @AcBAG, @cBGender, @CriminalOffence)", myCon);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@ID", txtID.Text);
cmd.Parameters.AddWithValue("@AgeGroup", cBAG.Text);
cmd.Parameters.AddWithValue("@Gender", cBGender.Text);
string str = "";
if (rBYes.Checked)
{
str = "Yes";
}
if (rBNo.Checked)
{
str = "No";
}
cmd.Parameters.AddWithValue("@CriminalOffence", SqlDbType.NVarChar).Value =
str;
}
And a method for creating a new record
private void btnNew_Click(object sender, EventArgs e)
{
txtID.Text = "";
cBAG.Text = "";
cBGender.Text = "";
rBYes.Text = "";
rBNo.Text = "";
}
An example of navigation button..
private void btnNextRec_Click(object sender, EventArgs e)
{
this.table1BindingSource.MoveNext();
}
ConnectionString...
myCon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\..
\Database1.mdb");
Please can someone help me here, thanks in advance
Parameter names must match the parameters in the SQL insert statement.

cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@ID", txtID.Text);
cmd.Parameters.AddWithValue("@AgeGroup", cbAG.Text);
cmd.Parameters.AddWithValue("@Gender", cbGender.Text);
cmd.Parameters.AddWithValue("@CriminalOffence", ((rBYes.Checked)? "Yes":"No"));
myCon.Open();
cmd.ExecuteNonQuery();
myCon.Close();
