I am trying to set up a method which allows me to archive a record which has been returned via a search box.
I have got the search query working however when I run the update query, the record still appears when searched for.
Can someone help?

I suspect the error is actually in your search query. When parenthesis are omitted the order of AND's and OR's are grouped. Try:
WHERE Contacts.Archived = 0 AND ((Surname = '" + textBox3.Text + "' OR Initial = '" + textBox3.Text + "') OR ([Post Town] = '" + textBox3.Text + "' OR[Post Code] = '" + textBox3 + "'))"

So i'm writing a program with C# and Sql, i created a database in visual studio and DataSet, and connected it to DataGridView. But the problem is, when i insert something into DataGridView row, all strings are presented as question marks, but with "int" type everything is okay.

I'll be glad to any help!
Edit: added code of the form for clarification
You can try the following steps to solve the problem about question marks in the datagirdview.
First, you could create the following table in your database.
CREATE TABLE [dbo].[Patient] (
[Id] INT NOT NULL,
[Name] NVARCHAR (50) NOT NULL,
[Age] INT NOT NULL,
[Address] NVARCHAR (50) NOT NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
Second, Please try the following code to use SqlParameters to insert data to database.
SqlConnection conn = new SqlConnection(#"CONNSTR");
void populate()
{
conn.Open();
string query = "select * from Patient";
SqlDataAdapter da = new SqlDataAdapter(query, conn);
SqlCommandBuilder builder = new SqlCommandBuilder(da);
var ds = new DataSet();
da.Fill(ds);
dataGridView1.DataSource = ds.Tables[0];
conn.Close();
}
private void Form1_Load(object sender, EventArgs e)
{
populate();
}
private void button1_Click(object sender, EventArgs e)
{
if (txtId.Text == "" || txtName.Text == "" || txtAge.Text == "" || txtAddress.Text == "" )
MessageBox.Show("Пустые поля не принимаются!");
else
{
conn.Open();
string query = "insert into Patient(Id,Name,Age,Address)values(#Id,#Name,#Age,#Address)";
SqlCommand cmd = new SqlCommand(query, conn);
cmd.Parameters.AddWithValue("#Id",Convert.ToInt32(txtId.Text));
cmd.Parameters.AddWithValue("#Name", txtName.Text);
cmd.Parameters.AddWithValue("#Age", Convert.ToInt32(txtAge.Text));
cmd.Parameters.AddWithValue("#Address", txtAddress.Text);
cmd.ExecuteNonQuery();
MessageBox.Show("Запись успешно добавлена!");
conn.Close();
populate();
}
}
Result:

using System.Collections.Generic;

using System.Data;
using System.Data.SqlClient;
using System.Drawing;

textBox2.Text = supName;
textBox3.Text = cno;
textBox4.Text = email;

textBox6.Text = city;

this is for update the record
i want to reload datagridview after clicking on refresh button

here i want to refresh my Datagridview after clicking Button5
private void button5_Click(object sender, EventArgs e)

con.Close();
dataGridView1.DataSource = ds.Tables;
dataGridView1.RefreshEdit();
}
catch (Exception exp)
{
MessageBox.Show("Error : "+ exp);
}
}
}
}
i was tried lots of solution but these are not working for my code
add this code for refresh the dataGridView
this.supplierTableAdapter.Fill(this.shopManagerDataSet.supplier);
this.dataGridView1.DataSource = this.shopManagerDataSet.supplier;
this.dataGridView1.Refresh();
I wanted to add an if statement to this code that says..
IF i click this button , it will check if the ListU.SelectedValue is empty or not , and if it is empty , a messagebox saying "please pick a name before continuing" , and if it is not empty , the code then runs.
how do i do that?
this is the code for the button click. (i know , my code needs some parameter , we can ignore that for the moment)
private void button4_Click(object sender, EventArgs e)
{
//update code//
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "Data Source=PEWPEWDIEPIE\\SQLEXPRESS;Initial Catalog=master;Integrated Security=True";
conn.Open();
SqlDataAdapter daCount = new SqlDataAdapter("select iCount from ComDet where cName = #cName", conn);
daCount.SelectCommand.Parameters.Add("#cName", SqlDbType.VarChar).Value = ListU.SelectedValue;
DataTable dtC = new DataTable();
daCount.Fill(dtC);
DataRow firstRow = dtC.Rows[0];
string x = firstRow["iCount"].ToString();
int y = Int32.Parse(x);
int z = y + 1;
SqlCommand cmdC = conn.CreateCommand();
cmdC.CommandText = "Update ComDet set iCount = " + z + ", ViewTime = '" + lblTime.Text + "', LastView = '" + txtUser2.Text + "' Where cName = '" + ListU.SelectedValue.ToString() + "'";
cmdC.ExecuteNonQuery();
conn.Close();
var ufdet = new UserFullDetail(ListU.SelectedValue.ToString());
ufdet.ShowDialog();
}
private void button4_Click(object sender, EventArgs e)
{
if(ListU.SelectedValue == null || ListU.SelectedValue.ToString() == string.Empty)
{
MessageBox.Show("Select something from the listbox, please");
return;
}
.....
Try like this
private void button4_Click(object sender, EventArgs e)
{
if(ListU.SelectedValue == null || ListU.SelectedValue.ToString() == string.Empty)
{
MessageBox.Show("Select something from the listbox, please");
}
else
{
//update code//
SqlConnection conn = new SqlConnection();
conn.ConnectionString = "Data Source=PEWPEWDIEPIE\\SQLEXPRESS;Initial Catalog=master;Integrated Security=True";
conn.Open();
SqlDataAdapter daCount = new SqlDataAdapter("select iCount from ComDet where cName = #cName", conn);
daCount.SelectCommand.Parameters.Add("#cName", SqlDbType.VarChar).Value = ListU.SelectedValue;
DataTable dtC = new DataTable();
daCount.Fill(dtC);
DataRow firstRow = dtC.Rows[0];
string x = firstRow["iCount"].ToString();
int y = Int32.Parse(x);
int z = y + 1;
SqlCommand cmdC = conn.CreateCommand();
cmdC.CommandText = "Update ComDet set iCount = " + z + ", ViewTime = '" + lblTime.Text + "', LastView = '" + txtUser2.Text + "' Where cName = '" + ListU.SelectedValue.ToString() + "'";
cmdC.ExecuteNonQuery();
conn.Close();
var ufdet = new UserFullDetail(ListU.SelectedValue.ToString());
ufdet.ShowDialog();
}
}
I prefer this:
private void button4_Click(object sender, EventArgs e)
{
if (ListU.SelectedItem == null)
{
MessageBox.Show("Please pick a name before continuing.");
}
else
{
// Run the code.
}
}
This makes the else condition explicit, rather than implied as in Steve's example.
Another approach would be to only enable button4 if something is selected in ListU, e.g.,
private void ListU_SelectedIndexChanged(object sender, System.EventArgs e)
{
button4.Enabled = ListU.SelectedItem != null;
}
Try this:
private void button4_Click(object sender, EventArgs e)
{
if(ListU.SelectedValue == null || string.IsNullOrEmpty(Convert.ToString(ListU.SelectedValue)))
{
MessageBox.Show("Select something from the listbox.");
return;
}
.....

You declare and initialise trid to 100 at the top of your code example;
static int trid = 100;
Nowhere in your example are you then setting its value to anything returned from your database query.
If you are storing the increment value in your database, you need to obtain the value using a query and then assign the value to trid before you use it.
If you are not storing the increment value in your database, you could use the number of rows returned in a query as an increment value and assign that to trid.
