DataGridViewRowPostPaintEventArgs.RowIndex Property

Gets the index of the current DataGridViewRow.

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

public int RowIndex { get; }

Property Value

Type: System.Int32
The index of the current DataGridViewRow.

The row index can be used to access the current row within a DataGridViewRowCollection.

The following code example demonstrates how to use the RowIndex property to access the current row. The code gets the value of the cell at the intersection of the selected row and the third column, and then paints this value over the entire row. The variable, e, is of type DataGridViewRowPostPaintEventArgs. This code example is part of a larger example provided in How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control.

// Get the content that spans multiple columns.
object recipe =

if (recipe != null)
    String text = recipe.ToString();

    // Calculate the bounds for the content that spans multiple  
    // columns, adjusting for the horizontal scrolling position  
    // and the current row height, and displaying only whole 
    // lines of text.
    Rectangle textArea = rowBounds;
    textArea.X -= this.dataGridView1.HorizontalScrollingOffset;
    textArea.Width += this.dataGridView1.HorizontalScrollingOffset;
    textArea.Y += rowBounds.Height - e.InheritedRowStyle.Padding.Bottom;
    textArea.Height -= rowBounds.Height -
    textArea.Height = (textArea.Height / e.InheritedRowStyle.Font.Height) *

    // Calculate the portion of the text area that needs painting.
    RectangleF clip = textArea;
    clip.Width -= this.dataGridView1.RowHeadersWidth + 1 - clip.X;
    clip.X = this.dataGridView1.RowHeadersWidth + 1;
    RectangleF oldClip = e.Graphics.ClipBounds;

    // Draw the content that spans multiple columns.
        text, e.InheritedRowStyle.Font, forebrush, textArea);
