How to reduce the padding/margin of DataGridView cells?

[Hans Merkl]

Hi,

It seems by default the text that is drawn within a DataGridView control
has several pixels of margin or padding around it. For my application I
need a very compact display so I would like to reduce that padding but I
can't figure out how to do it.
I have found the Padding property of DefaultCellStyle but that is already
set to 0 so the padding I am seeing must come from somewhere else.

Does anybody know how to reduce the padding?

Thanks

Hans

Hi Hans,

Thank you for posting.

The Padding property of the DataGridView.DefaultCellStyle represents the
space between the edge of a DataGridViewCell and its content. Setting the
Padding property only affects where the editing control of the
DataGridViewCell is drawn.

The margin or padding you see in the cells is between the text and the cell
bound. If you want to reduce the padding, I think you should handle the
DataGridView's CellPainting event to draw the cells by yourself.

Here is a sample for you.

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.dataGridView1.CellPainting += new
DataGridViewCellPaintingEventHandler(dataGridView1_CellPainting);
}

void dataGridView1_CellPainting(object sender,
DataGridViewCellPaintingEventArgs e)
{
// ignore the column header and row header cells
if (e.RowIndex != -1 && e.ColumnIndex != -1)
{
e.PaintBackground(e.ClipBounds, true);
e.Graphics.DrawString(Convert.ToString(e.FormattedValue),
e.CellStyle.Font, Brushes.Black, e.CellBounds.X, e.CellBounds.Y,
StringFormat.GenericDefault);
e.Handled = true;
}
}
}

Hope this is helpful to you.
