DataGridView.AutoResizeColumnHeadersHeight Method

Adjusts the height of the column headers to fit the contents of the largest column header.

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

public void AutoResizeColumnHeadersHeight()

This method is useful if you want to control when the column headers resize. The height of the column headers is adjusted only once per method call; if the contents of the column headers later change, the column headers will not automatically adjust. To set the column headers to automatically resize when their contents change, use the ColumnHeadersHeightSizeMode property.

For cell contents to wrap onto multiple lines when the column headers are resized, the cell style in effect for the cell must have a WrapMode property value of True.

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

The following code example demonstrates how to resize column headers and rows as a result of a button click.

private void button1_Click(object sender, System.EventArgs e)
{
    // Resize the height of the column headers. 
    dataGridView1.AutoResizeColumnHeadersHeight();

    // Resize all the row heights to fit the contents of all non-header cells.
    dataGridView1.AutoResizeRows(
        DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders);
}
