获取当前 DataGridViewRow 的边界。
public:
property System::Drawing::Rectangle RowBounds { System::Drawing::Rectangle get(); };public System.Drawing.Rectangle RowBounds { get; }member this.RowBounds : System.Drawing.RectanglePublic ReadOnly Property RowBounds As Rectangle属性值
表示当前 Rectangle 的边界的 DataGridViewRow。
示例
下面的代码示例演示如何使用 RowBounds 属性计算行的边界来绘制自定义背景。 变量 e的类型 DataGridViewRowPrePaintEventArgs。 此代码示例是 How to： Customize the Appearance of Rows in the Windows 窗体 DataGridView Control 中提供的较大示例的一部分。
// Determine whether the cell should be painted
// with the custom selection background.
if ((e.State & DataGridViewElementStates.Selected) ==
DataGridViewElementStates.Selected)
{
// 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);
// Paint the custom selection background.
using (Brush backbrush =
new System.Drawing.Drawing2D.LinearGradientBrush(rowBounds,
this.dataGridView1.DefaultCellStyle.SelectionBackColor,
e.InheritedRowStyle.ForeColor,
System.Drawing.Drawing2D.LinearGradientMode.Horizontal))
{
e.Graphics.FillRectangle(backbrush, rowBounds);
}
}
' Determine whether the cell should be painted with the
' custom selection background.
If (e.State And DataGridViewElementStates.Selected) = _
DataGridViewElementStates.Selected Then
' Calculate the bounds of the row.
Dim rowBounds As New Rectangle( _
Me.dataGridView1.RowHeadersWidth, e.RowBounds.Top, _
Me.dataGridView1.Columns.GetColumnsWidth( _
DataGridViewElementStates.Visible) - _
Me.dataGridView1.HorizontalScrollingOffset + 1, _
e.RowBounds.Height)
' Paint the custom selection background.
Dim backbrush As New _
System.Drawing.Drawing2D.LinearGradientBrush(rowBounds, _
Me.dataGridView1.DefaultCellStyle.SelectionBackColor, _
e.InheritedRowStyle.ForeColor, _
System.Drawing.Drawing2D.LinearGradientMode.Horizontal)
Try
e.Graphics.FillRectangle(backbrush, rowBounds)
Finally
backbrush.Dispose()
End Try
End If
注解
属性的 RowBounds 宽度与宽度 DataGridView相同。 若要获取列中 DataGridView的宽度，请使用 GetColumnsWidth 该方法。
