Hi guys,

I'm new the this forum where I'm hoping to get some friendly advice for a bit-of-a-newbie C# programmer. I've been through 2 differnt beginners courses on the code so now i'm ready to get my hands in the code!

I'm currently having a problem with loading all data from Columns into a list view I made. The SQL Database was being read fine and eahc line was being pulled into 3 seperate text boxes but I decided I wanted it all in a list view.

However, I'm not to sure how to alter my code to show this. Below I have attached my working code:

 private void NavigateRecords()
        {
            DataRow dRow = ds1.Tables["Workers"].Rows[inc];

            ListViewItem item = new ListViewItem(dRow.ItemArray.GetValue(1).ToString());
            item.SubItems.Add(dRow.ItemArray.GetValue(2).ToString());
            item.SubItems.Add(dRow.ItemArray.GetValue(3).ToString());

            listView1.Items.Add(item);

As you can see I know that the 'Get Value' is only pointing to 1 line in the table. Is there an easy was to modifying this code to pull through all the data from the 3 columns at once? Sorry its a real n00b question but I really want to crack this one.

Thanks for any help you can offer!

regards
Mark.

How about using a foreach loop?

foreach (DataRow row in table.Rows)
{
    item.SubItems.Add(row["name of the column of that row"].ToString());
}

Hope this answer your question.

Hi wen,

Thanks for your response. I have tried that but I canot get it to work.. Below I have posted more of the code to show people what I'm trying to do:

       private void Form1_Load(object sender, EventArgs e)
        {
            con = new System.Data.SqlClient.SqlConnection();
            ds1 = new DataSet();

            con.ConnectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\MyWorkers.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";



            string sql = "SELECT * FROM tblWorkers";
            da = new System.Data.SqlClient.SqlDataAdapter(sql, con);

            con.Open();

            da.Fill(ds1, "Workers");
            NavigateRecords();
            MaxRows = ds1.Tables["Workers"].Rows.Count;

            con.Close();




        }

        private void NavigateRecords()
        {

            DataRow dRow = ds1.Tables["Workers"].Rows[inc];



            ListViewItem item = new ListViewItem(dRow["first_Name"].ToString());

            item.SubItems.Add(dRow["last_Name"].ToString());
            item.SubItems.Add(dRow["job_Title"].ToString());

            listView1.Items.Add(item);

            //textBox1.Text = dRow.ItemArray.GetValue(1).ToString();
            //textBox2.Text = dRow.ItemArray.GetValue(2).ToString();
            //textBox3.Text = dRow.ItemArray.GetValue(3).ToString();

        }

I welcome any help available.

Kind regards
Mark

Good morning, Anyone up this bright and early that can offer some advice on where to put the 'foreach' looping statement?

Hi Mark,

Just trying to clear the air. I was wondering if you have an error or could mention what seems to be the problem? Can you retrieve the information (like display the information on a textbox)? Because if you can, then I can assume your database connection is alright, and all you need to do is to assign the value into a list using a loop.

If I were to give an answer now, I think you should add the for loop starting from line 28. Hope to hear from you soon.

Regards,
Wen

Good morning Wen, Thank you for your reply.

Please note, that I was able to fix it.. I used the following code:

       private void NavigateRecords()
        {

            DataTable dtable = ds1.Tables["Workers"];


            for (int i = 0; i < dtable.Rows.Count; i++)
            {

                DataRow dRow = ds1.Tables["Workers"].Rows[inc];



                ListViewItem item = new ListViewItem(dRow["first_Name"].ToString());

                item.SubItems.Add(dRow["last_Name"].ToString());
                item.SubItems.Add(dRow["job_Title"].ToString());

                listView1.Items.Add(item);

            }

            //textBox1.Text = dRow.ItemArray.GetValue(1).ToString();
            //textBox2.Text = dRow.ItemArray.GetValue(2).ToString();
            //textBox3.Text = dRow.ItemArray.GetValue(3).ToString();

        }

I needed to add ' DataTable dtable = ds1.Tables["Workers"];' and then...

for (int i = 0; i < dtable.Rows.Count; i++)

thanks for your help guys.
