データを連結する先の ASP.NET サーバーコントロールプロパティの名前を取得します。

名前空間: System.Web.UI
アセンブリ: System.Web (system.web.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 PropertyName As String

Visual Basic (使用法)

Dim instance As DataBinding
Dim value As String

value = instance.PropertyName

public string PropertyName { get;
 }

C++

public:
property String^ PropertyName {
    String^ get ();
}

/** @property */
public String get_PropertyName ()

JScript

public function get PropertyName
 () : String

プロパティ値
データの連結先のプロパティ。

使用例

DataBinding のオブジェクト (myDataBinding2) のさまざまなプロパティにアクセスする 3 つの変数 (dataBindingOutput1、dataBindingOutput2、dataBindingOutput3) を宣言するコード例を次に示します。この例では、次に、PropertyName プロパティの値を dataBindingOutput1 に代入し、文字列 "The property name is " と連結して、その結果の値をファイルに書き込んでいます。

Visual Basic

    ' Use the DataBindingCollection.GetEnumerator method
    ' to iterate through the myDataBindingCollection object
    ' and write the PropertyName, PropertyType, and Expression
    ' properties to a file for each DataBinding object
    ' in the MyDataBindingCollection object. 
    myDataBindingCollection = DataBindings
    Dim myEnumerator As IEnumerator = myDataBindingCollection.GetEnumerator()

    While myEnumerator.MoveNext()
        myDataBinding2 = CType(myEnumerator.Current, DataBinding)
        Dim dataBindingOutput1, dataBindingOutput2, dataBindingOutput3
 As [String]
        dataBindingOutput1 = [String].Concat("The property name
 is ", myDataBinding2.PropertyName)
        dataBindingOutput2 = [String].Concat("The property type
 is ", myDataBinding2.PropertyType.ToString(), "-",
 dataBindingOutput1)
        dataBindingOutput3 = [String].Concat("The expression is
 ", myDataBinding2.Expression, "-", dataBindingOutput2)
        WriteToFile(dataBindingOutput3)

        myDataBindingExpression2 = [String].Concat("<%#",
 myDataBinding2.Expression, "%>")
        myStringReplace2 = myDataBinding2.PropertyName.Replace(".",
 "-")
        myHtmlControlDesignBehavior.SetAttribute(myStringReplace2, myDataBindingExpression2)
        Dim index As Integer
 = myStringReplace2.IndexOf("-"c)
    End While ' while loop ends
End Sub 'OnBindingsCollectionChanged
