Add new font for all the cells in a DataGridView

Introduction

In this article, we will Add new font for all the cells in a DataGridView.

Straight to Experiment

Let us create a "Windows Forms Application" and add a "DataGridView" as under

Next in the code behind create a class as under

public class FileInformation        
{
	public string FileName { get; set; }
	public string Download { get { return "Download File"; } }        
}

This class holds the information about "FileName" and the "Download" link.

Next let us write the code that will give a good look and fell to our grid

private void PrepareGrid()
{

	var fileNameColumn = new DataGridViewTextBoxColumn
	{
		Name = @"FileName",
		HeaderText = "File Name",
		DataPropertyName = @"FileName",
		AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill,
		ReadOnly = false,
		Frozen = false
	};
	dataGridView1.Columns.Add(fileNameColumn);

	var downloadColumn = new DataGridViewLinkColumn

	{
		Name = @"Download",
		HeaderText = @"Download",
		DataPropertyName = @"Download",
		AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill,
		ReadOnly = true
	};
	dataGridView1.Columns.Add(downloadColumn);
	this.dataGridView1.AllowUserToAddRows = false;
	this.dataGridView1.AllowUserToDeleteRows = false;
	this.dataGridView1.AllowUserToResizeRows = false;
	this.dataGridView1.RowHeadersVisible = false;
	this.dataGridView1.MultiSelect = false;
	this.dataGridView1.SelectionMode = DataGridViewSelectionMode.RowHeaderSelect;
	this.dataGridView1.AutoGenerateColumns = false; 
}

In the "PrepareGrid()" method, we are giving mainly a Name, HeaderText and DataPropertyName to the columns that should participate in the DataGridViewControl.

Once done, the next task is to populate the grid content

private void DisplayResult()
{
	FileInformationList = LoadItems();
	dataGridView1.DataSource = FileInformationList;
}

private List<FileInformation> LoadItems()
{
	var lstScriptInfo = new List<FileInformation>();
	for (int i = 1; i <= 5; i++)
	{
		lstScriptInfo.Add(new FileInformation { FileName = "File" + i.ToString() + ".txt" });
	}
	return lstScriptInfo;
}

The code is preety straight forward.We are preparing a list of 5 items and binding the same to the grid

Next write the code in the Cell Painting event of the DataGridViewControl

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
	string familyName = "Courier New";
	float emSize = 8.5f;
	dataGridView1.Columns["FileName"].DefaultCellStyle.Font = new System.Drawing.Font(familyName, emSize);
	dataGridView1.Columns["Download"].DefaultCellStyle.Font = new System.Drawing.Font(familyName, emSize);

}

We are adding the needed font family name and size to the cells.
