Implicit Conversion From Data Type Datetime To Int Is Not Allowed. Use The CONVERT Function To Run This Query.

Hey im trying to store a category name and the date into a database. For some reason i keep getting this error

 Implicit conversion from data type datetime to int is not allowed. Use the CONVERT function to run this query.

This error is the error im getting back from the database. the datetime field in the database is a datatype (DateTime) so what exactly is going on ?protected void InsertNewCat_Click(object sender, EventArgs e)

{                    string insertSql = "INSERT into Category (CategoryName,Date) VALUES (@Category, @Date)";

                    string conString = WebConfigurationManager.ConnectionStrings["ProCo"].ConnectionString;                    SqlConnection con = new SqlConnection(conString);

                    SqlCommand cmd = new SqlCommand(insertSql, con);                   cmd.Parameters.AddWithValue("@Category", NewCat.Text);

                    cmd.Parameters.AddWithValue("@Date",DateTime.Now);

 

try

{

              con.Open();             int update = cmd.ExecuteNonQuery();            CatInsertStatus.Text = update.ToString() + " record updated.";

}catch (Exception Err)

{

             CatInsertStatus.Text = Err.Message;

}

finally

{

             con.Close();

}

}
