DataGridView::InvalidateRow Method (Int32)

 

Invalidates the specified row of the DataGridView, forcing it to be repainted.

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

public:
void InvalidateRow(
	int rowIndex
)

Parameters

rowIndex
Type: System::Int32

The index of the row to invalidate.

ArgumentOutOfRangeException

rowIndex is not in the valid range of 0 to the number of rows minus 1.

Use this method to force a row to repaint itself. This method is useful in owner-drawing scenarios where you handle the RowPrePaint or RowPostPaint events.

For more information about painting and invalidation, see Invalidate.

The following code example illustrates how to use the InvalidateRow method in a row-painting scenario. In the example, the row is invalidated when the current cell changes, forcing the row to repaint itself.

This code is part of a larger example available in How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control.
