Introduction

In this article we will see how to disable and grey out any specific listviewitem based on condition.

Step 1: Create windows forms application

Form.cs

  1. using System;
  2. using System.Collections.Generic;
  3. using System.ComponentModel;
  4. using System.Data;
  5. using System.Drawing;
  6. using System.Linq;
  7. using System.Text;
  8. using System.Threading.Tasks;
  9. using System.Windows.Forms;
  11. namespace ListView_DisableSpecificItem
  12. {
  13. public partial class Form1 : Form
  14. {
  15. public Form1()
  16. {
  17. InitializeComponent();
  18. }
  20. SchoolManagementEntities objSchoolManagementEntities = new SchoolManagementEntities();
  21. private void Form1_Load(object sender, EventArgs e)
  22. {
  23. var query = from r in objSchoolManagementEntities.Students select r;
  27. foreach (var p in query)
  28. {
  29. ListViewItem item = new ListViewItem();
  31. item.Text = p.FirstName;
  33. if (item.Text == "Andy")
  34. {
  35. item.BackColor = System.Drawing.Color.Gray;
  36. }
  38. listView1.Items.Add(item);
  39. }
  40. }
  42. private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
  43. {
  44. if (e.IsSelected && e.Item.Text == "Andy")
  45. {
  46. e.Item.Selected = false;
  47. }
  48. }
  49. }
  50. }

Output of the application looks like this
