I have two combo boxes "Year" & "Amount" on the top of them I do get values for user info, because there are text boxes when called with user ID text boxes fill up with correct data.
The two combo boxes are also filled with correct data but I have to manually select year and the amount corresponding to it.
I need help in when I call the data "Year" & "Amount" should appear visible in the combo box. When I select a Year then the Amount should change accordingly. Last but not the least my reset is not clearing the combo boxes.

I would be inclined to simplify things a bit. Treat the personal data and the finance data as 2 parts.
Firstly, request the personal data - keep it simple
private void btnSearch_Click(object sender, EventArgs e)
{
string sql = "SELECT MemberId, Name, Address, Cellular, Email FROM Members WHERE MemberId = #Id";
SqlConnection con = new SqlConnection("myconnectionstring");
SqlCommand cmd = new SqlCommand(sql,con);
cmd.Parameters.Add("#Id",SqlDbType.Int).Value = tbID.Text;
DataTable dt = new DataTable();
try
{
con.Open();
dt.Load(cmd.ExecuteReader());
con.Close();
}
catch (Exception ex)
{
con.Close();
Console.WriteLine(ex.Message);
}
tbID.Text = dt.Rows[0]["MemberId"].ToString();
tbName.Text = dt.Rows[0]["Name"].ToString();
tbCellular.Text = dt.Rows[0]["Cellular"].ToString();
tbEmail.Text = dt.Rows[0]["Email"].ToString();
tbAddress.Text = dt.Rows[0]["Address"].ToString();
}
Once thats done, move on to second part - the years/amounts combo (which is almost identical code)
string sql = "SELECT Year, Amount FROM Payments WHERE MemberId = #Id"
SqlConnection con = new SqlConnection("myconnectionstring");
SqlCommand cmd = new SqlCommand(sql,con);
cmd.Parameters.Add("#Id",SqlDbType.Int).Value = tbID.Text;
DataTable dt = new DataTable();
try
{
con.Open();
dt.Load(cmd.ExecuteReader());
con.Close();
}
catch (Exception ex)
{
con.Close();
Console.WriteLine(ex.Message);
}
cmbYear.DataSource = dt;
cmbYear.DisplayMember = "Year";
cmbYear.ValueMember = "Amount";
And finally, tell the textbox what it needs to read by using
private void cmbYear_SelectionChangeCommitted(object sender, EventArgs e)
{
amountTxt.Text = cmbYear.SelectedValue.ToString();
}
in the combobox's SelectionChangeCommitted event
And that should have you sorted!

Basically, what I want to delete an entry form a dataviewtable which pulls data through from MySql. I thought this would be done fairly by effectively copying the modify code and substituting it for 'DELETE'. However, from the code below, you can clearly see that hasn't worked. I will copy most of my code for you:
private void button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=DESKTOP-HNR3NJB\\mysql;Initial Catalog=stock;Integrated Security=True");
var sqlQuery = "";
if (IfProductsExists(con, textboxProductID.Text))
{
con.Open();
sqlQuery = #"DELETE FROM [Products] WHERE [ProductID] = '" + textboxProductID.Text + "'";
SqlCommand cmd = new SqlCommand(sqlQuery, con);
cmd.ExecuteNonQuery();
con.Close();
}
else
{
MessageBox.Show("Record doesn't exist!", "ERROR:", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
//Reading Data
LoadData();
}
So that's the delete button's code now for the add button and load data function
Add button:
private void button2_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(#"Data Source=DESKTOP-HNR3NJB\mysql;Initial Catalog=stock;Integrated Security=True");
//insert logic
con.Open();
if(textboxProductID.Text == "" || textboxProductName.Text == "")
{
MessageBox.Show("You have to enter either a product ID or product name", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
else
{
bool status = false;
if (comboboxStatus.SelectedIndex == 0)
{
status = true;
}
else
{
status = false;
}
var sqlQuery = "";
if (IfProductsExists(con, textboxProductID.Text))
{
sqlQuery = #"UPDATE [Products] SET [ProductName] = '" + textboxProductName.Text + "' ,[ProductStatus] = '" + status + "' WHERE [ProductID] = '" + textboxProductID.Text + "'";
}
else
{
sqlQuery = #"INSERT INTO [Stock].[dbo].[Products] ([ProductID],[ProductName],[ProductStatus]) VALUES
('" + textboxProductID.Text + "','" + textboxProductName.Text + "','" + status + "')";
}
SqlCommand cmd = new SqlCommand(sqlQuery, con);
cmd.ExecuteNonQuery();
con.Close();
textboxProductID.Clear();
textboxProductName.Clear();
LoadData();
}
}
LoadData function:
public void LoadData()
{
SqlConnection con = new SqlConnection(#"Data Source=DESKTOP-HNR3NJB\mysql;Initial Catalog=stock;Integrated Security=True");
//reading data from sql
SqlDataAdapter sda = new SqlDataAdapter("Select * From [stock].[dbo].[Products]", con);
DataTable dt = new DataTable();
sda.Fill(dt);
dataGridView1.Rows.Clear();
foreach (DataRow item in dt.Rows)
{
int n = dataGridView1.Rows.Add();
dataGridView1.Rows[n].Cells[0].Value = item["ProductID"].ToString();
dataGridView1.Rows[n].Cells[1].Value = item["ProductName"].ToString();
if ((bool)item["ProductStatus"])
{
dataGridView1.Rows[n].Cells[2].Value = "Active";
}
else
{
dataGridView1.Rows[n].Cells[2].Value = "Deactive";
}
}
}
You're going to need the IfProductsExists method too:
private bool IfProductsExists(SqlConnection con, string productCode)
{
SqlDataAdapter sda = new SqlDataAdapter("Select 1 From [Products] WHERE [ProductID]='" + productCode + "'", con);
DataTable dt = new DataTable();
if (dt.Rows.Count > 0)
return true;
else
return false;
}
It's going to be an inventory system that's going to be used at work for the sale and inventory management of IT equipment.

SqlConnection con = new SqlConnection(ss);

How can I insert and save data into the database using Visual Studio and C#?
This code throws an error. Anyone please give the suggestion to me to solve the error.

At first make sure your the data type of different column of customer table.
Then make sure what type of data you have to save for combobox.
you have to get the selected value from your Combobox. combobox1,combobox2,combobox3 retuns only the class name
System.Windows.Forms.ComboBox
Besides others, it is recommended to use parameter .. like this:
You can follow this example
private void button1_Click(object sender, EventArgs e)
{
using(SqlConnection con = new SqlConnection(#"Data Source=(LocalDB)\v11.0;AttachDbFilename=c:\users\abdul samad\documents\visual studio 2013\Projects\newpro\newpro\Database1.mdf;Integrated Security=True"))
{
try
{
using (var cmd = new SqlCommand("INSERT INTO registor (Name, FullName, Password, Email, Gander) VALUES (#Name,#Fullname,#Password,#Email, #Gander)"))
{
cmd.Connection = con;
cmd.Parameters.Add("#Name", txtfname.Text);
cmd.Parameters.Add("#Fullname", txtfname.Text);
cmd.Parameters.Add("#Password", txtpass.Text);
cmd.Parameters.Add("#Email", txtemail.Text);
cmd.Parameters.Add("#Gander", comboBox1.GetItemText(comboBox1.SelectedItem));
con.Open()
if(cmd.ExecuteNonQuery() > 0)
{
MessageBox.Show("Record inserted");
}
else
{
MessageBox.Show("Record failed");
}
}
}
catch (Exception e)
{
MessageBox.Show("Error during insert: " + e.Message);
}
}
}
The comments are getting a bit busy, so this is the sort of thing you need to do (including parameterising the query):
Specifically, you don't need a reader for an insert statement as it doesn't return a result set.
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
var sql = "insert into dbo.customer ...";
using (var con = new SqlConnection(ss))
{
var cmd = new SqlCommand(sql , con);
con.Open();
cmd.ExecuteScalar();
MessageBox.Show("Welcome to our gym");
}
}
Hi check that customer table is available in gym Database.
else try this link
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand("insert into customer (name,weight,height,add_class,gender,fees) values(#name,#weight,#height,#add_class,#gender,#fees)", con);
cmd.Parameters.AddWithValue("name", this.textBox1.Text);
if (con.State == ConnectionState.Closed)
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
I found that your connection string declaration is wrong
public string ss = "Data Source=D\\SQLEXPRESS;Initial Catalog=gym;Integrated Security=True";
need to update like below
public string ss = "Data Source=abc\\SQLEXPRESS;Initial Catalog=gym; user id=sa; Password=123456";
Data source will be not be D, It should be Server name.

I have two textboxes and two buttons on one site. The problem is that this second textbox and second button doesn't work. First textbox+button doing well:
int NoOfDigTextBoxEngine;
protected void TextBoxADDEngine_TextChanged(object sender, EventArgs e)
{
NoOfDigTextBoxEngine = TextBoxADDEngine.Text.Length;
}
protected void ButtonADDEngine_Click(object sender, EventArgs e)
{
String strConnString = ConfigurationManager.ConnectionStrings["AppConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(strConnString))
{
SqlCommand cmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
DataSet ds = new DataSet();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT Engine, Created, LastChange, WhoInserted, WhoLastModified, Disable FROM PartsEngine";
cmd.Connection = con;
sda.SelectCommand = cmd;
if (FillWhoIsLogged > 0) // ----------------Wypełnianie tebeli kiedy jest ktos zalogowany--- //
{
if (NoOfDigTextBoxEngine == 7)
{
try
{
Convert.ToInt32(TextBoxADDEngine.Text);
con.Open();
cmd.CommandText = ("INSERT INTO PartsEngine ([Engine], [Created], [WhoInserted], [Disabled]) VALUES ('" + TextBoxADDEngine.Text + "', GETDATE(), '" + FillWhoIsLogged + "', '1');");
cmd.ExecuteNonQuery();
GridView3.DataBind();
TextBoxADDEngine.Text = string.Empty;
con.Close();
}
catch
{
Response.Write("<script type='text/javascript'> alert('Nr Silnika może zawierać jedynie cyfry.')</script>");
TextBoxADDEngine.Text = string.Empty;
}
}
else
{
Response.Write("<script type='text/javascript'> alert('Nr Silnika musi mieć 7 cyfr.Podano: " + NoOfDigTextBoxEngine + " ')</script>");
TextBoxADDEngine.Text = string.Empty;
}
}
}
}
But the second (is the same) don't want to work.
int NoOfDigTextBoxGear;
protected void TextBoxADDGear_TextChanged(object sender, EventArgs e)
{
NoOfDigTextBoxGear = TextBoxADDGear.Text.Length;
}
protected void ButtonADDGear_Click(object sender, EventArgs e)
{
String strConnString = ConfigurationManager.ConnectionStrings["AppConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(strConnString))
{
SqlCommand cmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
DataSet ds = new DataSet();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT Gear, Created, LastChange, WhoInserted, WhoLastModified, Disable FROM PartsGear";
cmd.Connection = con;
sda.SelectCommand = cmd;
if (FillWhoIsLogged > 0) // ----------------Wypełnianie tebeli kiedy jest ktos zalogowany--- //
{
if (NoOfDigTextBoxGear == 7)
{
try
{
Convert.ToInt32(TextBoxADDGear.Text);
con.Open();
cmd.CommandText = ("INSERT INTO PartsGear ([Gear], [Created], [WhoInserted], [Disabled]) VALUES ('" + TextBoxADDGear.Text + "', GETDATE(), '" + FillWhoIsLogged + "', '1');");
cmd.ExecuteNonQuery();
GridView5.DataBind();
TextBoxADDGear.Text = string.Empty;
con.Close();
}
catch
{
Response.Write("<script type='text/javascript'> alert('Nr Skrzyni może zawierać jedynie cyfry.')</script>");
TextBoxADDGear.Text = string.Empty;
}
}
else
{
Response.Write("<script type='text/javascript'> alert('Nr Skrzyni musi mieć 7 cyfr. Podano: "+ NoOfDigTextBoxGear +" ')</script>");
TextBoxADDGear.Text = string.Empty;
}
}
}
}
When i write something in second textbox and then click button- always NoOfDigTextBoxGear = 0...why?
It's not make any sense for me because this code(for second textbox and button) is the same like the the first one(for first textbox and button).
Oh... i just saw this:
<asp:TextBox ID="TextBoxADDGear" runat="server" Visible="False"
Width="96px"></asp:TextBox>
I didn't add ontextchanged(!)
ontextchanged="TextBoxADDGear_TextChanged"
Now everything is ok.
I have this basic WinForms application user interface:
And I want to add the data both to the DataGridView and the sql table, when the "Gem" button is clicked. I have this following code:
private void Form2_Load(object sender, EventArgs e)
{
try
{
con = new SqlConnection();
con.ConnectionString = #"Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Produkt.mdf;Integrated Security=True";
con.Open();
//adap = new SqlDataAdapter("select SN, FName as 'Navn', MName as 'Vare nr', LName as 'Antal', Age from Produkt", con);
string sql = "SELECT Navn, Varenr, Antal, Enhed, Priseksklmoms, Konto FROM ProduktTable";
adap = new SqlDataAdapter(sql, con);
ds = new System.Data.DataSet();
adap.Fill(ds, "ProduktTable");
dataGridView1.DataSource = ds.Tables["ProduktTable"];
}
catch (Exception ex)
{
MessageBox.Show("Error\n" + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
private void button1_Click(object sender, EventArgs e)
{
string navn = textBox2.Text;
int varenr = int.Parse(textBox3.Text);
float antal = (float)Convert.ToDouble(textBox4.Text);
string enhed = textBox5.Text;
string konto = comboBox2.Text;
float pris = (float)Convert.ToDouble(textBox6.Text);
dataGridView1.Rows[0].Cells[0].Value = navn;
dataGridView1.Rows[0].Cells[1].Value = varenr;
string StrQuery;
try
{
SqlCommand comm = new SqlCommand();
comm.Connection = con;
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
StrQuery = #"INSERT INTO ProduktTable VALUES ('"
+ dataGridView1.Rows[i].Cells[0].Value + "',' "
+ dataGridView1.Rows[i].Cells[1].Value + "');";
comm.CommandText = StrQuery;
comm.ExecuteNonQuery();
}
}
catch (Exception ex)
{
MessageBox.Show("Error\n" + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
This is just an example with the purpose for storing the string "navn" and the integer "Varenr" in the DataGridView and the sql. When Im running the application and clicking on the button, following error occurs:
My column names for my ProduktTable table are exactly the same as the column names for the dataGridView.
Thanks in advance
Explicitly set your column names in the insert statement...
StrQuery = #"INSERT INTO ProduktTable (Navn, Varenr) VALUES ('"
+ dataGridView1.Rows[i].Cells[0].Value + "',' "
+ dataGridView1.Rows[i].Cells[1].Value + "');";
Can anybody tell me why my database isn't updating? Here's my code:
protected void editSection_selected(object sender, EventArgs e) {
int index = grdPhone.SelectedIndex;
GridViewRow row = grdPhone.Rows[index+1];
string values = ((DropDownList)sender).SelectedValue;
int tempVal = Convert.ToInt32(values);
int caseage = Convert.ToInt32(keyId);
int value = tempVal;
/*OleDbConnection con = new OleDbConnection(strConnstring);
//string query = "Update Categories set HRS_LEVEL_AMOUNT=" + tempVal + " where parent_id=65 and ID=" + caseage;
string query = "Delete HRS_LEVEL_AMOUNT from Categories where parent_id=65 and id=" + caseage;
OleDbCommand cmd = new OleDbCommand(query, con);
con.Open();
cmd.ExecuteNonQuery();
con.Dispose();
cmd.Dispose();
con.Close();
accPhoneNumbers.UpdateCommand = "Update Categories set HRS_LEVEL_AMOUNT=" + tempVal + " where parent_id=65 and ID=" + caseage;
*/
string str = "UPDATE Categories SET HRS_LEVEL_AMOUNT = ? WHERE ID=?";
using (OleDbConnection con = new OleDbConnection(strConnstring))
{
using (OleDbCommand cmd = new OleDbCommand(str, con))
{
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("HRS_LEVEL_AMOUNT", tempVal);
cmd.Parameters.AddWithValue("ID", caseage);
con.Open();
cmd.ExecuteNonQuery();
}
}
Label1.Text += " editSection Success! (B) " + tempVal;
}
The commented part is my first solution (including the accPhoneNumbers.UpdateCommand).
I really need your help guys.
I hope this can help you:
string str = "UPDATE Categories SET HRS_LEVEL_AMOUNT = #value1 WHERE ID=#value2";
using (OleDbConnection con = new OleDbConnection(strConnstring))
{
using (OleDbCommand cmd = new OleDbCommand(str, con))
{
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("#value1", tempVal);
cmd.Parameters.AddWithValue("#value2", caseage);
con.Open();
cmd.ExecuteNonQuery();
con.close();
}
}
