DataGridCell.ColumnNumber 属性

获取或设置 System.Windows.Forms.DataGrid 控件中某列的列号。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property ColumnNumber As Integer
用法
Dim instance As DataGridCell
Dim value As Integer

value = instance.ColumnNumber

instance.ColumnNumber = value

public int ColumnNumber { get; set; }

public:
property int ColumnNumber {
    int get ();
    void set (int value);
}

/** @property */
public int get_ColumnNumber ()

/** @property */
public void set_ColumnNumber (int value)

public function get ColumnNumber () : int

public function set ColumnNumber (value : int)

属性值

该列的列号。

备注

可使用 ColumnNumber 值指定与 System.Windows.Forms.DataGrid 控件关联的 DataTable 中的 DataColumn。

示例

下面的示例将 System.Windows.Forms.DataGrid 的 CurrentCell 属性分配给 DataGridCell。同时通过使用 RowNumber 和 ColumnNumber 属性指定 DataRow 和 DataColumn 对象来返回存储在 DataTable 中的值。

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

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);
}

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.get_CurrentCell();
    BindingManagerBase bm = get_BindingContext().
        get_Item(thisGrid.get_DataSource(), 
        thisGrid.get_DataMember());
    DataRowView drv = (DataRowView)(bm.get_Current());
    Console.WriteLine(drv.get_Item(myDataGridCell.get_ColumnNumber()));
    Console.WriteLine(myDataGridCell.get_RowNumber());
} //PrintCell
