DataGridView.AutoResizeColumnHeadersHeight Method (Int32)
Adjusts the height of the column headers based on changes to the contents of the header in the specified column.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
columnIndex is not in the valid range of 0 to the number of columns minus 1.
This method is useful if you want to control when the column headers resize if only the contents of the header in the specified column have changed as a result of user edits or changes to a bound data source. The height of the column headers is adjusted only once per method call if the content change requires it; 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 more information about programmatic resizing, see Sizing Options in the Windows Forms DataGridView Control.
