如何在C＃中使用不同的线程连续填充两个dataGridView？

问题描述

我创建了两个dataGridViews和一个开始按钮。



当我按下开始按钮时，使用代理MyDel创建了两个线程t1和t2。



实际上，我希望连续填充dataGridView1和dataGridView2。但只有dataGridView2会不断更新。 dataGridView2完成后，dataGridView1开始更新。



任何人都可以给我建议如何解决这个问题？

I have created two dataGridViews and a start button.

When I press the Start button two threads t1 and t2 are created using the delegate MyDel.

Actually, I want both dataGridView1 and dataGridView2 to be populated continuously. But only dataGridView2 is getting updated continuously. After the completion of dataGridView2, dataGridView1 starts updating.

Can anyone please give me suggestion how to fix this?

using System;
using System.Windows.Forms;
using System.Threading;

namespace MultiThreadedDataGridViewDemo
{
    public partial class Form1 : Form
    {
        private delegate void MyDel();

        int count=0;
        int count_1 = 0;

        public Form1()
        {    
            InitializeComponent();
            for (int p = 0; p < 37; p++)
            {
                dataGridView1.Columns.Add("", "");// dynamic cloumn adding
                dataGridView1.Rows.Add();//dynamic row adding
                dataGridView1.Columns[p].SortMode = DataGridViewColumnSortMode.NotSortable;//Disables the column header sorting
                dataGridView1.Columns[p].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
                dataGridView1.Columns[p].Width = 70;

                dataGridView2.Columns.Add("", "");// dynamic cloumn adding
                dataGridView2.Rows.Add();//dynamic row adding
                dataGridView2.Columns[p].SortMode = DataGridViewColumnSortMode.NotSortable;//Disables the column header sorting
                dataGridView2.Columns[p].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
                dataGridView2.Columns[p].Width = 70;

            }
        }
        //Populates dataGridView1
        public void Method1()
        {
            while (count < 10000)
            {
                for (int i = 0; i < dataGridView1.Rows.Count; i++)
                {
                    for (int k = 0; k < dataGridView1.Columns.Count; k++)
                    {

                        dataGridView1.Rows[i].Cells[k].Value = count;
                    }
                }
                count++;
            }
        }
        //Populates dataGridView2
        public void Method2()
        {
            while (count_1 < 10000)
            {
                for (int i = 0; i < dataGridView2.Rows.Count; i++)
                {
                    for (int k = 0; k < dataGridView2.Columns.Count; k++)
                    {
                        dataGridView2.Rows[i].Cells[k].Value = count_1;
                    }
                }
                count_1++;
            }                  
        }

        //Starts the threads to populate dataGridView1 and dataGridView1
        private void btn_Start_Click(object sender, EventArgs e)
        {
                MyDel del_1 = new MyDel(Method1);
                Thread t1 = new Thread(new ThreadStart(del_1));
                t1.Start();

                MyDel del_2 = new MyDel(Method2);
                Thread t2 = new Thread(new ThreadStart(del_2));
                t2.Start();
        }
    }
}
