GetExtent() メソッド

バンドの絶対幅を返します。

シンタックス

Visual Basic

'宣言
 
Public Overloads Function GetExtent() As Integer

C#

public int GetExtent()

解説

GetExtentメソッドでグリッドのコンテナーのスケール モードを使用して、バンドの合計幅を返すことができます。このメソッドは、バンドが表示される量、ColScrollRegionのサイズ、またはシステムで使用できる画面領域のサイズを考慮しません。バンド全体を表示するために必要となる合計幅を単純に計算します。

使用例

Visual Basic

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid
Imports System.Diagnostics

   Private Sub Button112_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button112.Click

       Dim bands As BandsCollection = Me.UltraGrid1.DisplayLayout.Bands

       ' Loop through all the bands.
       Dim band As UltraGridBand
       For Each band In bands
           ' Get the origin and the extent.
           Dim origin As Integer = band.GetOrigin(BandOrigin.PreRowArea)
           Dim extent As Integer = band.GetExtent(BandOrigin.PreRowArea)

           ' Write out the origin and the extent.
           Debug.WriteLine("bands(" & band.Index & ") Origin = " & origin & ", Extent = " & extent)
       Next

   End Sub
