DataGridView.AutoResizeColumns Method

Adjusts the width of all columns to fit the contents of all their cells, including the header cells.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public void AutoResizeColumns()

This method is useful if you want to control when columns resize. The column widths are adjusted only once per method call; if the contents of the columns later change, the columns will not automatically adjust. To resize a specific column, use the AutoResizeColumn method. To set the columns to automatically resize whenever their contents change, use the AutoSizeColumnsMode property or the column AutoSizeMode property.

For more information about programmatic resizing, see Sizing Options in the Windows Forms DataGridView Control.

The following code example resizes all columns to fit the contents of the columns and the column headers. This code example is part of a larger example provided in How to: Programmatically Resize Cells to Fit Content in the Windows Forms DataGridView Control.

private void SizeAllColumns(Object sender, EventArgs e)
{
    dataGridView1.AutoResizeColumns(
        DataGridViewAutoSizeColumnsMode.AllCells);
}
