I am experimenting with an application that will give me CPU Usage, Memory Usage, and I want to expand it from there. Right now it goes to two Text Boxes. I combined it into the first text box 

How do I display each value in two GridView Columns?

Here is what I have now;

using System;
using System.Diagnostics;
using System.Data;
using System.Windows.Forms;
 
namespace MemOV
{
    public partial class FrmMain : Form
    {
        private PerformanceCounter cpuCounter;
        private PerformanceCounter ramCounter;
 
        public FrmMain()
        {
            InitializeComponent();
            InitializeCpuCounter();
            InitializeRamCounter();
            updateTimer.Start();
        }
 
        private void UpdateTimerTick(object sender, EventArgs e)
        {
            this.textBox1.Text = "CPU Usage: " + Convert.ToInt32(cpuCounter.NextValue()).ToString() + "%" + "  | " + "Memory Usage: " + Convert.ToInt32(ramCounter.NextValue()).ToString() + "Mb";
            this.textBox2.Text = Convert.ToInt32(ramCounter.NextValue()).ToString() + "Mb";
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
 
        }
 
        private void InitializeCpuCounter()
        {
            cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);
        }
 
        private void InitializeRamCounter()
        {
            ramCounter = new PerformanceCounter("Memory", "Available MBytes", true);
        }
    }
}

Hi Brian,

Thank you for contacting us.

First you can add the two columns to the grid:
public Form1()
{
    InitializeComponent();
 
    GridViewTextBoxColumn cpuColumn= new GridViewTextBoxColumn("CPU");
    cpuColumn.Width = 250;
    cpuColumn.ReadOnly = true;
    radGridView1.Columns.Add(cpuColumn);
 
    GridViewTextBoxColumn ramColumn = new GridViewTextBoxColumn("RAM");
    ramColumn.Width = 70;
    ramColumn.ReadOnly = true;
    radGridView1.Columns.Add(ramColumn);
 
    radGridView1.AllowAddNewRow = false;
    radGridView1.Rows.AddNew();
}

Then you can directly set the column values in the tick event:
private void UpdateTimerTick(object sender, EventArgs e)
{
    radGridView1.Rows[0].Cells["CPU"].Value = "CPU Usage: " + Convert.ToInt32(cpuCounter.NextValue()).ToString() + "%" + "  | " + "Memory Usage: " + Convert.ToInt32(ramCounter.NextValue()).ToString() + "Mb";
 
    radGridView1.Rows[0].Cells["RAM"].Value = Convert.ToInt32(ramCounter.NextValue()).ToString() + "Mb";
}

Please let me know if there is something else I can help you with.

Dimitar, thank you. That is exactly what I am looking for. I have a follow on question. If I want to add the Private working memory of a process, say Notepad.exe for example how would I add that in?

Thanks

Hello Brian,

Thank you for writing back.

You can add new row and set the value of the cell just like before:
Process[] currentProcesess;
  
public Form1()
{
    InitializeComponent();
    
    currentProcesess = System.Diagnostics.Process.GetProcessesByName("notepad");
      
    foreach (Process item in currentProcesess)
    {
        radGridView1.Rows.Add(item.ProcessName + " " + item.WorkingSet64);
    }
}
  
private void UpdateTimerTick(object sender, EventArgs e)
{
    for (int i = 0; i < currentProcesess.Length; i++)
    {
        radGridView1.Rows[i + 1].Cells["CPU"].Value = currentProcesess[i].ProcessName + " " + currentProcesess[i].WorkingSet64; //assumes that you already have one row for the cpu usage
    }
}

I hope this helps.

Thanks Dimitar, I see that it adds it as a separate row item. I added another column.

This is what I have now; I left the TextBoxes that I first used just so I could validate the correct data made in in the field, so that can be removed.

I will take a look at the videos you referenced. Thanks!
