DataGrid.IsExpanded(Int32) 方法

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取一个值，该值指示指定行的节点是展开还是折叠的。

public:
 bool IsExpanded(int rowNumber);

public bool IsExpanded (int rowNumber);

member this.IsExpanded : int -> bool

Public Function IsExpanded (rowNumber As Integer) As Boolean

参数

rowNumber

Int32

工作行的行号。

返回

Boolean

如果该节点是展开的，则为 true；否则为 false。

示例

下面的代码示例测试网格中的每一行，并打印展开行的行数。

protected:
   void TextExpanded( DataGrid^ myGrid )
   {
      // Get the DataTable of the grid
      DataTable^ myTable;
      // Assuming the grid is bound to a DataTable
      myTable = (DataTable^)(myGrid->DataSource);
      for ( int i = 0; i < myTable->Rows->Count; i++ )
      {
         if ( myGrid->IsExpanded( i ) )
         {
            Console::WriteLine( "Row {0} was expanded", i );
         }
      }
   }

protected void TextExpanded(DataGrid myGrid){
    // Get the DataTable of the grid
    DataTable myTable;
    // Assuming the grid is bound to a DataTable
    myTable = (DataTable) myGrid.DataSource;
    for(int i = 0;i < myTable.Rows.Count ;i++) {
       if(myGrid.IsExpanded(i)) {
          Console.WriteLine("Row " + i + " was expanded");
       }
    }
 }

Protected Sub TextExpanded(myGrid As DataGrid)
    ' Get the DataTable of the grid
    Dim myTable As DataTable
    ' Assuming the grid is bound to a DataTable
    myTable = CType(myGrid.DataSource, DataTable)
    Dim i As Integer
    For i = 0 To myTable.Rows.Count - 1
        If myGrid.IsExpanded(i) Then
            Console.WriteLine(("Row " & i & " was expanded"))
        End If
    Next i
End Sub
