GetSibling(SiblingRow) メソッド

兄弟行を返します (存在する場合)

シンタックス

Visual Basic

'宣言
 
Public Overloads Function GetSibling( _
   ByVal sibling As SiblingRow _
) As UltraGridRow

C#

public UltraGridRow GetSibling( 
   SiblingRow sibling
)

パラメータ

sibling

返す兄弟を指定します

戻り値の型

兄弟行 (存在する場合)

解説

このメソッドを起動して、行の最初、最後、次、または前の兄弟行への参照を返します。兄弟行が存在しない場合、このメソッドは Nothing を返します。

spanbands 引数は、他のバンドの行が兄弟と考えられるかどうかを示すために使用できます。

HasNextSibling および HasPrevSibling メソッドを起動して、行がその前後に兄弟行をそれぞれ持つかどうかを決定します。

GetChild メソッドおよび HasParent プロパティを使用して、子行および親行への参照をそれぞれ返すことができます。
