DataGridView.AutoResizeRow Method (Int32)
Adjusts the height of the specified row to fit the contents of all its cells including the header cell.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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.
For more information about programmatic resizing, see Sizing Options in the Windows Forms DataGridView Control.
The following code example resizes the third row in a DataGridView to fit the column contents. 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.
