Load listview using custom class in C#.net

Step 1: Create a window application

Step 2: Add a Listview(lsvUserDetails) and Button(btnShow)

             Add three columns and name it as
                       i)No
                      ii)Name
                      iii)Department
               
                 Modify Listview Properties
                     i) Change the  view  to Details   
                     ii)Change GridLines  to True


                 

Step 3:Create the datatable(dtUserDetails) globally as below 

           DataTable dtUserDetails = new DataTable();

 

 Step 4: Write a method CreateDatatable

public void CreateDatatable()

        {

            //Create a datatable and add three columns

            dtUserDetails.Columns.Add("No", typeof(int));

            dtUserDetails.Columns.Add("Name", typeof(string));

            dtUserDetails.Columns.Add("Department", typeof(string));

            //Add values to the datatable

            DataRow drow1 = dtUserDetails.NewRow();

            drow1["No"] = 1;

            drow1["Name"] = "Vivekanandan";

            drow1["Department"] = "Software Engineer";

            DataRow drow2 = dtUserDetails.NewRow();

            drow2["No"] = 2;

            drow2["Name"] = "Ismail";

            drow2["Department"] = "Software Engineer";

            DataRow drow3 = dtUserDetails.NewRow();

            drow3["No"] = 3;

            drow3["Name"] = "Velmurugan";

            drow3["Department"] = "Team Leader";

            dtUserDetails.Rows.Add(drow1);

            dtUserDetails.Rows.Add(drow2);

            dtUserDetails.Rows.Add(drow3);

        }

 Step 5: Write a custom class (clsLsvUserDetails)

private class clsLsvUserDetails : ListViewItem

        {

            private DataRow _drData = null;

            public clsLsvUserDetails(DataRow dr): base()

            {

                _drData = dr;

                this.Text = _drData["No"].ToString();

                this.SubItems.Add(_drData["Name"].ToString());

                this.SubItems.Add(_drData["Department"].ToString());

            }

        }

 

Step 6: On button click event(btnShow_Click) write the below code

private void btnShow_Click(object sender, EventArgs e)

        {

            CreateDatatable();

            lsvUserDetails.Items.Clear();

            clsLsvUserDetails oItem = null;

            if (dtUserDetails != null)

            {

                foreach (DataRow dr in dtUserDetails.Rows)

                {

                    oItem = new clsLsvUserDetails(dr);

                    lsvUserDetails.Items.Add(oItem);

                }

            }

        }

Step 7: Click the Show button
