datagridview adding rows from a thread

yasser_ja asked:

Open original thread
hi,

I'm trying to test threading using datagridview.
The scenario is:

1- A form has (button1), (datagridview1).
2- Once I click (button1) a thread will start and start adding rows until I click again the (button1).

I did it like this:

C#
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;


private void button1_Click(object sender, EventArgs e)
        {
            

            Thread thread = new Thread(new ThreadStart(WorkThreadFunction));
            if (thread.ThreadState == ThreadState.Running)
            {
                thread.Abort();
                return;
            }
            thread.Start();
        }
public void WorkThreadFunction()
        {
            try
            {
                dataGridView1.Rows.Add(new object[] { "test" });

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }




But unfortunately, it didn't work and I got an error:
Cross-thread operation not valid



Please help me with an easy tips (edit my code if you can) because I'm not that much experienced with such things.


Thanks,

  4. Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.
