I have created two dataGridViews and a start button as shown in the Figrue.
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();
//Cells are created in dataGridView1 and dataGridView2
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;
}
}
//Method to populate 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++;
}
}
//Method to populate 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++;
}
}
//Creates 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();
}
}
}
