System.Windows.Forms.dll

Sumber:

DataGridViewRowPostPaintEventArgs.cs

Mendapatkan indeks dari .DataGridViewRow

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

public int RowIndex { get; }

member this.RowIndex : int

Public ReadOnly Property RowIndex As Integer

Nilai Properti

Int32

Indeks dari .DataGridViewRow

Contoh

Contoh kode berikut menunjukkan cara menggunakan RowIndex properti untuk mengakses baris saat ini. Kode mendapatkan nilai sel di persimpangan baris yang dipilih dan kolom ketiga, lalu melukis nilai ini di seluruh baris. Variabel, e, berjenis DataGridViewRowPostPaintEventArgs. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan dalam Cara: Menyesuaikan Tampilan Baris di Kontrol DataGridView Formulir Windows.

// Get the content that spans multiple columns.
object recipe =
    this.dataGridView1.Rows.SharedRow(e.RowIndex).Cells[2].Value;

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 -
        e.InheritedRowStyle.Padding.Bottom;
    textArea.Height = (textArea.Height / e.InheritedRowStyle.Font.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;
    e.Graphics.SetClip(clip);

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

    e.Graphics.SetClip(oldClip);
}

' Get the content that spans multiple columns.
Dim recipe As Object = _
    Me.dataGridView1.Rows.SharedRow(e.RowIndex).Cells(2).Value

If (recipe IsNot Nothing) Then
    Dim text As String = 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.
    Dim textArea As Rectangle = rowBounds
    textArea.X -= Me.dataGridView1.HorizontalScrollingOffset
    textArea.Width += Me.dataGridView1.HorizontalScrollingOffset
    textArea.Y += rowBounds.Height - e.InheritedRowStyle.Padding.Bottom

    textArea.Height = (textArea.Height \ e.InheritedRowStyle.Font.Height) * _
        e.InheritedRowStyle.Font.Height

    ' Calculate the portion of the text area that needs painting.
    Dim clip As RectangleF = textArea
    clip.Width -= Me.dataGridView1.RowHeadersWidth + 1 - clip.X
    clip.X = Me.dataGridView1.RowHeadersWidth + 1
    Dim oldClip As RectangleF = e.Graphics.ClipBounds
    e.Graphics.SetClip(clip)

    ' Draw the content that spans multiple columns.
    e.Graphics.DrawString(text, e.InheritedRowStyle.Font, forebrush, _
        textArea)

    e.Graphics.SetClip(oldClip)
End If
