This article provides an example of how datagridview handles unbound columns in c#Share it for your reference.The implementation is as follows:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using datagridview1.DataSet1TableAdapters;
namespace datagridview1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
CustomersTableAdapter adapter = new CustomersTableAdapter();
bindingSource1.DataSource = adapter.GetData();
dataGridView1.AutoGenerateColumns = false;
int newColIndex = dataGridView1.Columns.Add("CompanyName", "CompanyName");
dataGridView1.Columns[newColIndex].DataPropertyName = "CompanyName";
newColIndex = dataGridView1.Columns.Add("ContactName", "ContactName");
dataGridView1.Columns[newColIndex].DataPropertyName = "ContactName";
newColIndex = dataGridView1.Columns.Add("Phone", "Phone");
dataGridView1.Columns[newColIndex].DataPropertyName = "Phone";
newColIndex = dataGridView1.Columns.Add("Contact", "Contact");
dataGridView1.CellFormatting += OnCellFormatting;
dataGridView1.DataSource = bindingSource1;
}
private void OnCellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (e.ColumnIndex == dataGridView1.Columns["Contact"].Index)
{
e.FormattingApplied = true;
DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
e.Value = string.Format("{0}:{1}", row.Cells["ContactName"].Value, row.Cells["Phone"].Value);
}
}
}
}
I hope that the description in this paper will be helpful to everyone's C#program design.
