I want the symptoms to have their own cell but the name and other things to be a single cell only.
Loop through your checked items like this:
foreach(var item in clbSymptoms.CheckedItems)
{
using (var cmd = new SqlCommand(sql, conn))
{
cmd.Parameters.Add("#fName", SqlDbType.VarChar, 50).Value = txtFName.Text.Substring(0, 1).ToUpper() + txtFName.Text.Substring(1);
cmd.Parameters.Add("#MName", SqlDbType.VarChar, 50).Value = txtMName.Text.Substring(0, 1).ToUpper() + txtMName.Text.Substring(1);
cmd.Parameters.Add("#lName", SqlDbType.VarChar, 50).Value = txtLName.Text.ToUpper();
cmd.Parameters.Add("#patientAge", SqlDbType.Int).Value = txtAge.Text;
cmd.Parameters.Add("#purok", SqlDbType.VarChar, 50).Value = cbPurok.Text;
cmd.Parameters.Add("#caseClass", SqlDbType.VarChar, 50).Value = cbClass.Text;
cmd.Parameters.Add("#questionnaire", SqlDbType.VarChar, 50).Value = "(1)" + cbQuestion1.Checked + " " + "(2)" + cbQuestion2.Checked;
cmd.Parameters.Add("#symptoms", SqlDbType.VarChar, 50).Value = item.ToString();
cmd.Parameters.Add("#date", SqlDbType.DateTime).Value = DateTime.Now;
cmd.ExecuteNonQuery();

I want to do update and insert in one button.

The problem is that you open a DataReader with the Command object cmd.
Then, before you close the DataReader, you try to re-purpose the same cmd object and Execute it.
You have to close the DataReader before you can re-use the cmd object for an insert or update.
I am trying to insert into an access database. all the fields worked except for the "passwordx" field in which I get data type mismatch in criteria expression.
string commandSql = "INSERT INTO Members ( lastName, firstName, id, dob, phone, areaCodeNo, adress, cityNo, zipCode, email, active,passwordx) VALUES ( #lastName, #firstName, #id, #dob, #phone, #areaCodeNo, #adress, #cityNo, #zipCode, #email, #active,#passwordx); ";
OleDbCommand command = new OleDbCommand(commandSql, connection);
command.Parameters.Add("#lastName", OleDbType.VarChar, 100).Value = mem.lastName;
command.Parameters.Add("#firstName", OleDbType.VarChar, 100).Value = mem.firstName;
command.Parameters.Add("#id", OleDbType.VarChar, 100).Value = mem.id;
command.Parameters.Add("#dob", OleDbType.VarChar, 100).Value = mem.dob;
command.Parameters.Add("#phone", OleDbType.VarChar, 100).Value = mem.phone;
command.Parameters.Add("#areaCodeNo", OleDbType.Integer, 100).Value = mem.areaCodeNo;
command.Parameters.Add("#adress", OleDbType.VarChar, 100).Value = mem.adress;
command.Parameters.Add("#cityNo", OleDbType.Integer, 100).Value = mem.cityNo;
command.Parameters.Add("#zipCode", OleDbType.VarChar, 100).Value = mem.zipCode;
command.Parameters.Add("#email", OleDbType.VarChar, 100).Value = mem.email;
command.Parameters.Add("#passwordx", OleDbType.VarChar, 100).Value = mem.password;
command.Parameters.Add("#active", OleDbType.Boolean, 100).Value = mem.active;
connection.Open();
affectedRows = command.ExecuteNonQuery();
connection.Close();
thanks for the help.
Shuffle the last two parameters to match the sequence of your SQL:
command.Parameters.Add("#active", OleDbType.Boolean, 100).Value = mem.active;
command.Parameters.Add("#passwordx", OleDbType.VarChar, 100).Value = mem.password;
And a Boolean doesn't have a length.
I'm new to C# coding and this website so bear with me. On the button click I want my stored procedure to execute and populate the datagridview. When I run the application and click the button I keep getting an error saying:
"No mapping exists from object type System.Windows.Forms.DataGridViewTextBoxCell to a known managed provider native type."
How do I fix this? I've tried converting the parameters to their data types which doesn't seem to work either. I've been stuck on this for a while and am struggling to find anything on the internet about my specific error. Thank you.

Your issue is that you're trying to pass the Cell into the stored procedure. You need to pass in the cells value.
Also, because you've put a ';' at the end of the foreach call, your loop around the rows isn't doing anything. Assuming you're trying to insert all the rows from the datagridview, you'll need something like this...
using (SqlConnection sqlcn1 = new SqlConnection("My Server Connection String"))
{
sqlcn1.Open();
//Stored Procedure
using (SqlCommand sqlcmddel = new SqlCommand("My_Stored_Procedure", sqlcn1))
{
sqlcmddel.CommandType = CommandType.StoredProcedure;
sqlcmddel.ExecuteNonQuery();
}
foreach (DataGridViewRow row in dataGridView1.Rows)
{
using (SqlCommand sqlcmdins = new SqlCommand("My_Stored_Procedure", sqlcn1))
{
sqlcmdins.CommandType = CommandType.StoredProcedure;
//Stored Procedure
sqlcmdins.Parameters.Add("#sugnum", SqlDbType.Int).Value = row.Cells[0].Value;
sqlcmdins.Parameters.Add("#sugtype", SqlDbType.NVarChar, 50).Value = row.Cells[1].Value;
sqlcmdins.Parameters.Add("#buyerid", SqlDbType.NVarChar, 50).Value = row.Cells[2].Value;
sqlcmdins.Parameters.Add("#duedate", SqlDbType.DateTime).Value = row.Cells[3].Value;
sqlcmdins.Parameters.Add("#xrelqty", SqlDbType.Float).Value = row.Cells[4].Value;

SqlDataReader dr1 = cmd.ExecuteReader();
//dr1 = cmd.ExecuteReader();
string st = string.Empty;
while (dr1.Read())
{
st = dr1[0].ToString();
}
st = dr1[0].ToString();
return st;
Remove this line after your while loop:-
st = dr1[0].ToString();
You need to call the Read() method to actually read the date from DataReader object.
Also, it would be better if you will wrap your code within using block:-
using (SqlDataReader dr1 = cmd.ExecuteReader())
{
while (dr1.Read())
{
st = dr1[0].ToString(); //With Index
st = dr1["ColumnName"].ToString(); //With Column Name
}
}
Update:
Based on your comment, this is an Insert SP and you were trying to read the return value so you can't use SqlDataReader, if you want to return whether SP successfully inserted data, you can return status code like 1 for successfull insertion & 0 for failure or something. You can then read this return code like this:-
SqlParameter returnParameter = cmd.Parameters.Add("StatusCd", SqlDbType.Int);
returnParameter.Direction = ParameterDirection.ReturnValue;
cmd.ExecuteNonQuery();
int statusCode = (int)returnParameter.Value;
But if you want to return a text like you have mentioned Successfully Inserted, you need to add that as Output parameter because SQL can only return interger values, you can then retrieve this output value as:-
SqlParameter output = new SqlParameter("#code", SqlDbType.Int);
output.Direction = ParameterDirection.Output;
cmd.Parameters.Add(output);
cmd.ExecuteNonQuery();
st = output.Value.ToString();
Here, #code will be the ouput parameter in your SP, which you'll set as: SET #code = 'Insert successfull'.

Is there a way to create a Class to create SqlConnection with a SqlCommand for "Select", "Update", "Delete", etc. and just provide the table, the fields, parameters and the criteria so I don't have to write all this code every time.
Any help will really appreciate it.
Linq2Sql
Entity Framework
nHibernate
Dapper
BLToolkit
create a class with Singleton and then every time you want to do anything with SqlConnection
you can use the same object.
