DataGridView.AutoResizeRow Method (Int32, DataGridViewAutoSizeRowMode, Boolean)
Adjusts the height of the specified row using the specified size mode, optionally calculating the height with the expectation that column widths will subsequently be adjusted.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
'Declaration Protected Sub AutoResizeRow ( _ rowIndex As Integer, _ autoSizeRowMode As DataGridViewAutoSizeRowMode, _ fixedWidth As Boolean _ )
- Type: System.Int32
The index of the row to resize.
- Type: System.Windows.Forms.DataGridViewAutoSizeRowMode
One of the DataGridViewAutoSizeRowMode values.
- Type: System.Boolean
true to calculate the new height based on the current width of the columns; false to calculate the height with the expectation that the column widths will also be adjusted.
autoSizeRowMode is not a valid DataGridViewAutoSizeRowMode value.
rowIndex is not in the valid range of 0 to the number of rows minus 1.
This method is useful if you want to control when a row resizes. The row height is adjusted only once per method call; if the contents of the row later change, the row will not automatically adjust. To resize all rows, use the AutoResizeRows method. To set the row to automatically resize whenever its contents change, use the AutoSizeRowsMode property.
This overload lets you specify a sizing mode that calculates the new height based on values in a limited set of cells, such as those in displayed rows only. This improves performance when the control contains a large number of rows.
This overload is protected and is designed to enable you to achieve ideal cell height-to-width ratios in a derived DataGridView class. If fixedWidth is false, the row height will be calculated with the expectation that you will call the AutoResizeColumn or AutoResizeColumns method next.
