I'm working on a job about checking in and out of a school. And when I write ListViewItem this always gives an error:
Here is my code:
SqlDataAdapter da = new SqlDataAdapter("SELECT * FROM Alunos WHERE EntradaSaida = 0", conn);
DataTable dt = new DataTable();
da.Fill(dt);
for (int i = 0; i < dt.Rows.Count; i++)
{
DataRow dr = dt.Rows[i];
ListViewItem item = new ListViewItem(dr["ID"].ToString());
item.SubItems.Add(dr["Nome"].ToString());
item.SubItems.Add(dr["Sobrenome"].ToString());
item.SubItems.Add(dr["TurmaID"].ToString());
item.SubItems.Add(dr["Data"].ToString());
lvEntrada.Items.Add(item);
}
if (lvEntrada.SelectedItems.Count > 0)
{
conn.Open();
using (SqlCommand cmd = new SqlCommand("UPDATE Alunos SET ID =#ID EntradaSaida =#Entrada, Data = #Data ", conn))
{
cmd.Parameters.AddWithValue("#ID", ID);
cmd.Parameters.AddWithValue("#Data", DateTime.Now);
cmd.Parameters.AddWithValue("#Entrada", 1);
int rows = cmd.ExecuteNonQuery();
}
}
Add
using System.Windows.Forms;
at the top of your cs file.
Or you know what else.... don't pass in a parameter to your listView...
ListViewItem item = new ListViewItem();
item.SubItems.Add(dr["ID"].ToString());
item.SubItems.Add(dr["Nome"].ToString());
item.SubItems.Add(dr["Sobrenome"].ToString());
item.SubItems.Add(dr["TurmaID"].ToString());
item.SubItems.Add(dr["Data"].ToString());
lvEntrada.Items.Add(item);
What is lvEntrada? does it have a property named Items?
I am trying to fetch the imagepath of an image from the database and display it in an image control but the images are not being displayed. I tried :
public void FetchQimage()
{
connection.Open();
SqlCommand cmd = new SqlCommand("select image_path from Questionimage where sub_code = '" + Session["subject"] + "' ", connection);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
// for (int i = 0; i <= dt.Rows.Count - 1; i++)
// {
Image3.ImageUrl = dt.Rows[0]["image_path"].ToString();
}
}
The image path is in the format : D:\Project\projectxyz\image
I'm creating an inventory system which should display the products that needs to be restock. If the quantity of the product is only 5 it should display a message that says you need to restock now. But I don't know how to do that because I'm creating an Inventory System only and not Sales and Inventory so how should I deduct it if I don't have sales system? I'm sorry, hope u guys understand.
Here is my code:
public void all()
{
SqlConnection MySqlConnection;
DataTable p_table = new DataTable();
MySqlConnection = new SqlConnection("Data Source=christina\\sqlexpress;Initial Catalog=cafe_inventory;User ID=sa;Password=tina;");
MySqlConnection.Open();
SqlCommand command1 = new SqlCommand("Select * from inventory", MySqlConnection);
//Clear the datatable to prevent duplicate generation of data in gridview.
p_table.Clear();
SqlDataAdapter m_da = new SqlDataAdapter("Select * from inventory", MySqlConnection);
//DataSet ds = new DataSet();
//DataTable dtable = ds.Tables["empinfo1"];
m_da.Fill(p_table);
// Clear the ListView control
//listView3.Items.Clear();
// Display items in the ListView control
for (int i = 0; i < p_table.Rows.Count; i++)
{
DataRow drow = p_table.Rows[i];
// Only row that have not been deleted
if (drow.RowState != DataRowState.Deleted)
{
// Define the list items
//(drow["bnum"].ToString());
ListViewItem lvi = new ListViewItem(drow["pnum"].ToString());
lvi.SubItems.Add(drow["pname"].ToString());
lvi.SubItems.Add(drow["descr"].ToString());
lvi.SubItems.Add(((DateTime)drow["dater"]).ToShortDateString());
//lvi.SubItems.Add(drow["exp"].ToString());
lvi.SubItems.Add(((DateTime)drow["exp"]).ToShortDateString());
lvi.SubItems.Add(drow["qt"].ToString());
// Add the list items to the ListView
listView2.Items.Add(lvi);
}
}
}

Try This:
void DisplayLowQuantityItems()
{
MySqlConnection con = new MySqlConnection("Data Source=christina\\sqlexpress;
Initial Catalog=cafe_inventory;User ID=sa;Password=tina;");
MySqlCommand command = new MySqlCommand("Select pname from inventory
where qt < 5", con);
con.Open();
MySqlDataReader reader = commad.ExecuteReader();
StringBuilder productNames= new StringBuilder();
while(reader.Read())
{
productNames.Append(reader["pname"].ToString()+Environment.NewLine);
}
con.Close();
MessageBox.Show("Following Products quantity is lessthan 5\n"+productNames);
}

another way of checking your data
DataTable p_table = new DataTable();
con = new MySqlConnection("Data Source=christina\\sqlexpress;Initial
Catalog=cafe_inventory;User ID=sa;Password=tina;");
con.Open();
MySqlCommand command1 = new MySqlCommand("Select pname from inventory where
qt < 5", con);
p_table.load(command1.ExecuteReader());
As title said it all anyway I have a table is sql-server products.
Which has product id, name,price and cetegory.
what i did is i get data into 1st GridView category wise, and what i want is when i checked that particular row or multiple row and click select button it shuld show product name and price in 2nd gridview.
But what its do is it override the next selected item to previously selected item in 2nd gridview and shows onlu one row not multiple selected items.
can anybody help me ??
here is a code
protected void Button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox chbox = GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox;
if (chbox.Checked == true)
{
string conn = ConfigurationManager.ConnectionStrings["Test_T3ConnectionString2"].ConnectionString;
SqlConnection con = new SqlConnection(conn);
string query = "select prod_name,price from products where prod_id = '" + GridView1.Rows[i].Cells[1].Text + "'";
SqlCommand cmd = new SqlCommand(query, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView2.DataSource = dt;
GridView2.DataBind();
}
}
}
You binded the grid too many times.
protected void Button1_Click(object sender, EventArgs e) {
List<string> checkedIDs = new List<string>();
for (int i = 0; i < GridView1.Rows.Count; i++) {
CheckBox chbox = GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox;
if (chbox.Checked == true)
{
checkedIDs.Add("'" + GridView1.Rows[i].Cells[1].Text + "'");
}
}
string conn = ConfigurationManager.ConnectionStrings["Test_T3ConnectionString2"].ConnectionString;
SqlConnection con = new SqlConnection(conn);
string query = "select prod_name,price from products where prod_id in (" + string.Join(",", checkedIDs.ToArray()) + ")";
SqlCommand cmd = new SqlCommand(query, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView2.DataSource = dt;
GridView2.DataBind();
}
