メモ : このプロパティは、.NET Framework version 2.0 で新しく追加されたものです。

現在の DataGridViewCell の行インデックスを取得します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 RowIndex As Integer

Visual Basic (使用法)

Dim instance As DataGridViewCellPaintingEventArgs
Dim value As Integer

value = instance.RowIndex

public int RowIndex { get;
 }

C++

public:
property int RowIndex {
    int get ();
}

/** @property */
public int get_RowIndex ()

JScript

public function get RowIndex
 () : int

プロパティ値
現在の DataGridViewCell の行インデックス。

解説

列ヘッダーが描画される場合、RowIndex プロパティは -1 を返します。

使用例

このメンバの使用方法を次のコード例に示します。

Visual Basic

Private Sub dataGridView1_CellPainting(ByVal
 sender As Object, _
    ByVal e As System.Windows.Forms.DataGridViewCellPaintingEventArgs)
 _
    Handles dataGridView1.CellPainting

    If Me.dataGridView1.Columns("ContactName").Index
 = _
        e.ColumnIndex AndAlso e.RowIndex >= 0 Then

        Dim newRect As New
 Rectangle(e.CellBounds.X + 1, e.CellBounds.Y + 1, _
            e.CellBounds.Width - 4, e.CellBounds.Height - 4)
        Dim backColorBrush As New
 SolidBrush(e.CellStyle.BackColor)
        Dim gridBrush As New
 SolidBrush(Me.dataGridView1.GridColor)
        Dim gridLinePen As New
 Pen(gridBrush)

        Try

            ' Erase the cell.
            e.Graphics.FillRectangle(backColorBrush, e.CellBounds)

            ' Draw the grid lines (only the right and bottom lines;
            ' DataGridView takes care of the others).
            e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, _
                e.CellBounds.Bottom - 1, e.CellBounds.Right - 1, _
                e.CellBounds.Bottom - 1)
            e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1, _
                e.CellBounds.Top, e.CellBounds.Right - 1, _
                e.CellBounds.Bottom)

            ' Draw the inset highlight box.
            e.Graphics.DrawRectangle(Pens.Blue, newRect)

            ' Draw the text content of the cell, ignoring alignment.
            If Not (e.Value Is
 Nothing) Then
                e.Graphics.DrawString(CStr(e.Value), e.CellStyle.Font, _
                Brushes.Crimson, e.CellBounds.X + 2, e.CellBounds.Y + 2, _
                StringFormat.GenericDefault)
            End If
            e.Handled = True

        Finally
