public:
 property bool RowHeadersVisible { bool get(); void set(bool value); };
public bool RowHeadersVisible { get; set; }
member this.RowHeadersVisible : bool with get, set
Public Property RowHeadersVisible As Boolean

屬性值

Boolean

如果資料列標頭可見,則為 true,否則為 false。 預設為 true

範例

下列程式碼範例示範此成員的使用。

   // Instantiate the EventHandler.
public:
   void AttachRowHeaderVisibleChanged()
   {
      myDataGridTableStyle->RowHeadersVisibleChanged += gcnew EventHandler( this, &MyDataGridTableStyle_RowHeadersVisibleChanged::MyDelegateRowHeadersVisibleChanged );
   }

   // raise the event when RowHeadersVisible property is changed.
private:
   void MyDelegateRowHeadersVisibleChanged( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      String^ myString = "'RowHeadersVisibleChanged' event raised, Row Headers are";
      if ( myDataGridTableStyle->RowHeadersVisible )
            myString = String::Concat( myString, " visible" );
      else
            myString = String::Concat( myString, " not visible" );

      MessageBox::Show( myString, "RowHeader information" );
   }

   // raise the event when a button is clicked.
   void myButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      if ( myDataGridTableStyle->RowHeadersVisible )
            myDataGridTableStyle->RowHeadersVisible = false;
      else
            myDataGridTableStyle->RowHeadersVisible = true;
   }
// Instantiate the EventHandler.
public void AttachRowHeaderVisibleChanged()
{
   myDataGridTableStyle.RowHeadersVisibleChanged += new EventHandler (MyDelegateRowHeadersVisibleChanged);
}

// raise the event when RowHeadersVisible property is changed.
private void MyDelegateRowHeadersVisibleChanged(object sender, EventArgs e)
{
   string myString = "'RowHeadersVisibleChanged' event raised, Row Headers are";
   if (myDataGridTableStyle.RowHeadersVisible)
      myString += " visible";
   else
      myString += " not visible";

   MessageBox.Show(myString, "RowHeader information");
}

// raise the event when a button is clicked.
private void myButton_Click(object sender, System.EventArgs e)
{
   if (myDataGridTableStyle.RowHeadersVisible)
      myDataGridTableStyle.RowHeadersVisible = false;
   else
      myDataGridTableStyle.RowHeadersVisible = true;
}
' Instantiate the EventHandler.
Public Sub AttachRowHeaderVisibleChanged()
   AddHandler myDataGridTableStyle.RowHeadersVisibleChanged, AddressOf MyDelegateRowHeadersVisibleChanged
End Sub


' raise the event when RowHeadersVisible property is changed.
 Private Sub MyDelegateRowHeadersVisibleChanged(ByVal sender As Object, ByVal e As EventArgs)
     Dim myString As String = "'RowHeadersVisibleChanged' event raised, Row Headers are"
     If myDataGridTableStyle.RowHeadersVisible Then
         myString += " visible"
     Else
         myString += " not visible"
     End If
     MessageBox.Show(myString, "RowHeader information")
 End Sub


' raise the event when a button is clicked.
Private Sub myButton_Click(sender As Object, e As System.EventArgs)
   If myDataGridTableStyle.RowHeadersVisible Then
      myDataGridTableStyle.RowHeadersVisible = False
   Else
      myDataGridTableStyle.RowHeadersVisible = True
   End If
End Sub

備註

當資料列標頭可見時,如果基礎 DataTable 有相關的子資料工作表,就會在每個資料列標頭中顯示加號。

除非您將 物件新增 DataGridTableStyle 至 , GridTableStylesCollection 否則這個屬性將無法運作。 在那之前,設定此屬性將不會有任何作用。
