定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

來源:

DrawListViewItemEventArgs.cs

取得要拔的大小和位置 ListViewItem 。

public:
 property System::Drawing::Rectangle Bounds { System::Drawing::Rectangle get(); };

public System.Drawing.Rectangle Bounds { get; }

member this.Bounds : System.Drawing.Rectangle

Public ReadOnly Property Bounds As Rectangle

屬性值

Rectangle

Rectangle A 代表繪製的界限ListViewItem。

範例

以下程式碼範例示範如何在提供自訂控制圖ListView的應用程式中使用該Bounds屬性。 在這個例子中，事件的處理器 ListView.DrawItem 會為整個項目繪製背景。 除了細節檢視外，所有檢視中，這個處理器同時繪製前景文字。 在細節檢視中，前景文字會繪製在事件中 ListView.DrawSubItem 。

完整範例請參閱 DrawListViewItemEventArgs 概述參考主題。

// Draws the backgrounds for entire ListView items.
private void listView1_DrawItem(object sender,
    DrawListViewItemEventArgs e)
{
    if ((e.State & ListViewItemStates.Selected) != 0)
    {
        // Draw the background and focus rectangle for a selected item.
        e.Graphics.FillRectangle(Brushes.Maroon, e.Bounds);
        e.DrawFocusRectangle();
    }
    else
    {
        // Draw the background for an unselected item.
        using (LinearGradientBrush brush =
            new LinearGradientBrush(e.Bounds, Color.Orange,
            Color.Maroon, LinearGradientMode.Horizontal))
        {
            e.Graphics.FillRectangle(brush, e.Bounds);
        }
    }

    // Draw the item text for views other than the Details view.
    if (listView1.View != View.Details)
    {
        e.DrawText();
    }
}

' Draws the backgrounds for entire ListView items.
Private Sub listView1_DrawItem(ByVal sender As Object, _
    ByVal e As DrawListViewItemEventArgs) _
    Handles listView1.DrawItem

    If Not (e.State And ListViewItemStates.Selected) = 0 Then

        ' Draw the background for a selected item.
        e.Graphics.FillRectangle(Brushes.Maroon, e.Bounds)
        e.DrawFocusRectangle()

    Else

        ' Draw the background for an unselected item.
        Dim brush As New LinearGradientBrush(e.Bounds, Color.Orange, _
            Color.Maroon, LinearGradientMode.Horizontal)
        Try
            e.Graphics.FillRectangle(brush, e.Bounds)
        Finally
            brush.Dispose()
        End Try

    End If

    ' Draw the item text for views other than the Details view.
    If Not Me.listView1.View = View.Details Then
        e.DrawText()
    End If

End Sub

備註

此特性指定的位置相對於控制器的 ListView 左上角。

要取得 中特定部分 ListViewItem的界限，請使用以下 ListViewItem.GetBounds 方法。
