bool accountHasValue = int.TryParse(dataGridView1.Rows[e.RowIndex].Cells["AccountNumber"].Value.ToString(), out accountNumber);
if (accountHasValue)
{
cmd.Parameters.AddWithValue("#AccountNumber", accountNumber);
}
string accounts = dataGridView1.Rows[e.RowIndex].Cells["Account"].Value.ToString();
cmd.Parameters.AddWithValue("#Account", accounts);
DateTime datetime;
bool dateTimeHasValue = DateTime.TryParse(dataGridView1.Rows[e.RowIndex].Cells["Date"].Value.ToString(), out datetime);
if (dateTimeHasValue)
{
cmd.Parameters.AddWithValue("#Date", datetime);
}
string Description = dataGridView1.Rows[e.RowIndex].Cells["Description"].Value.ToString();
cmd.Parameters.AddWithValue("#Description", Description);
string Post_Ref = dataGridView1.Rows[e.RowIndex].Cells["Post_Ref"].Value.ToString();
cmd.Parameters.AddWithValue("#Post_Ref", Post_Ref);
int debit;
bool debitHasValue = Int32.TryParse(dataGridView1.Rows[e.RowIndex].Cells["Debit"].Value.ToString(), out debit);
if (debitHasValue)
{
cmd.Parameters.AddWithValue("#Debit", debit);
}
int Credits;
bool CreditsHasValue = Int32.TryParse(dataGridView1.Rows[e.RowIndex].Cells["Credit"].Value.ToString(), out Credits);
if (CreditsHasValue)

cmd.ExecuteNonQuery();
con.Close();
Load_data();
}

The error simply means the TryParse method does not have an overload that accepts one parameter. If you look at the documentation, it takes two parameters.
For the lines of code that use TryParse, first declare a variable and use it as out parameter and pass it for seeding your database. Show me the code !!! Ok, see examples below.
//For accountNumber
int accountNumber;
bool accountHasValue = int.TryParse(dataGridView1.Rows[e.RowIndex].Cells["AccountNumber"].Value, out accountNumber);
if(accountHasValue)
{
cmd.Parameters.AddWithValue("#AccountNumber", accountNumber);
}
//For Datetime
DateTime datetime;
bool dateTimeHasValue = DateTime.TryParse(dataGridView1.Rows[e.RowIndex].Cells["Date"].Value, out datetime);
if(dateTimeHasValue)
{
cmd.Parameters.AddWithValue("#Date", datetime);
}
//For Debit
int debit;
bool debitHasValue = Int32.TryParse(dataGridView1.Rows[e.RowIndex].Cells["Debit"].Value, debit);
if(debitHasValue )
{
cmd.Parameters.AddWithValue("#Debit", debit);
}
Basically all lines of code that you use the TryParse, implement them as above.
