Waarde van eigenschap
Een Rectangle die de grenzen van de huidige DataGridViewRowvertegenwoordigt.
Voorbeelden
In het volgende codevoorbeeld ziet u hoe u de RowBounds eigenschap gebruikt om de grenzen van de zichtbare cellen in een rij te bepalen. Dit codevoorbeeld maakt deel uit van een groter voorbeeld in How to: Het uiterlijk van rijen aanpassen in het Windows Forms DataGridView-besturingselement.
// Paints the content that spans multiple columns and the focus rectangle.
void dataGridView1_RowPostPaint(object sender,
DataGridViewRowPostPaintEventArgs e)
{
// Calculate the bounds of the row.
Rectangle rowBounds = new Rectangle(
this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
this.dataGridView1.Columns.GetColumnsWidth(
DataGridViewElementStates.Visible) -
this.dataGridView1.HorizontalScrollingOffset + 1,
e.RowBounds.Height);
SolidBrush forebrush = null;
try
{
// Determine the foreground color.
if ((e.State & DataGridViewElementStates.Selected) ==
DataGridViewElementStates.Selected)
{
forebrush = new SolidBrush(e.InheritedRowStyle.SelectionForeColor);
}
else
{
forebrush = new SolidBrush(e.InheritedRowStyle.ForeColor);
}
// 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);
}
}
finally
{
forebrush.Dispose();
}
if (this.dataGridView1.CurrentCellAddress.Y == e.RowIndex)
{
// Paint the focus rectangle.
e.DrawFocus(rowBounds, true);
}

Opmerkingen
De breedte van de RowBounds eigenschap is hetzelfde als de breedte van het DataGridView. Gebruik de methode om de breedte van de kolommen in de DataGridViewkolom op te GetColumnsWidth halen.
