DataGridCell.ColumnNumber 屬性

定義

取得或設定 DataGrid 控制項中的資料行編號。

public:
 property int ColumnNumber { int get(); void set(int value); };
public int ColumnNumber { get; set; }
member this.ColumnNumber : int with get, set
Public Property ColumnNumber As Integer

屬性值

Int32

資料行的編號。

範例

下列範例會將 CurrentCellSystem.Windows.Forms.DataGrid 屬性指派給 DataGridCell 。 透過 和 ColumnNumber 屬性指定 DataRowDataColumn 物件 RowNumber ,即可傳回儲存在 中的 DataTable 值。

void PrintCell( Object^ sender, MouseEventArgs^ /*e*/ )
{
   DataGrid^ thisGrid = dynamic_cast<DataGrid^>(sender);
   DataGridCell myDataGridCell = thisGrid->CurrentCell;
   BindingManagerBase^ bm = BindingContext[ thisGrid->DataSource,thisGrid->DataMember ];
   DataRowView^ drv = dynamic_cast<DataRowView^>(bm->Current);
   Console::WriteLine( drv[ myDataGridCell.ColumnNumber ] );
   Console::WriteLine( myDataGridCell.RowNumber );
}
private void PrintCell(object sender, MouseEventArgs e)
{
   DataGrid thisGrid = (DataGrid) sender;
   DataGridCell myDataGridCell = thisGrid.CurrentCell;
   BindingManagerBase bm = BindingContext[thisGrid.DataSource, thisGrid.DataMember];
   DataRowView drv = (DataRowView) bm.Current;
   Console.WriteLine(drv [myDataGridCell.ColumnNumber]);
   Console.WriteLine(myDataGridCell.RowNumber);
}
Private Sub PrintCell(sender As Object, e As MouseEventArgs)
   Dim thisGrid As DataGrid = CType(sender, DataGrid)
   Dim myDataGridCell As DataGridCell = thisGrid.CurrentCell
   Dim bm As BindingManagerBase = _
   BindingContext (thisGrid.DataSource, thisGrid.DataMember)
   Dim drv As DataRowView = CType(bm.Current, DataRowView)
   Console.WriteLine(drv(myDataGridCell.ColumnNumber))
   Console.WriteLine(myDataGridCell.RowNumber)
End Sub

備註

您可以使用 ColumnNumber 值,在 與 控制項相關聯的 System.Windows.Forms.DataGridDataTable 指定 DataColumn
