DataGridView.AutoResizeColumnHeadersHeight Method (Int32, Boolean, Boolean)

Adjusts the height of the column headers based on changes to the contents of the header in the specified column, optionally calculating the height with the expectation that the column and/or row header widths will subsequently be adjusted.

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

protected void AutoResizeColumnHeadersHeight(
	int columnIndex,
	bool fixedRowHeadersWidth,
	bool fixedColumnWidth
)

Parameters

columnIndex
Type: System.Int32

The index of the column header whose contents should be used to determine new height.

fixedRowHeadersWidth
Type: System.Boolean

true to calculate the new height based on the current width of the row headers; false to calculate the height with the expectation that the row headers width will also be adjusted.

fixedColumnWidth
Type: System.Boolean

true to calculate the new height based on the current width of the specified column; false to calculate the height with the expectation that the column width will also be adjusted.

ExceptionCondition
ArgumentOutOfRangeException

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 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.

This overload is protected and is designed to enable you to achieve ideal cell height-to-width ratios in a derived DataGridView class. If the fixedColumnWidth or fixedRowHeadersWidth parameters are false, the height of the column headers will be calculated with the expectation that you will call the methods such as AutoResizeColumns and AutoResizeRowHeadersWidth next.
