示例

以下示例将赋 DataGridCell 给 CurrentCell 所选 System.Windows.Forms.DataGrid 单元格的列和行号，并返回所选单元格的列和行号。 存储在该 DataTable 对象中的值也使用 DataGridCell 对象的 RowNumber 和 ColumnNumber。

void PrintCellRowAndCol()
{
   DataGridCell^ myCell;
   myCell = DataGrid1->CurrentCell;
   Console::WriteLine( myCell->RowNumber );
   Console::WriteLine( myCell->ColumnNumber );
   
   // Prints the value of the cell through the DataTable.
   DataTable^ myTable;
   
   // Assumes the DataGrid is bound to a DataTable.
   myTable = dynamic_cast<DataTable^>(DataGrid1->DataSource);
   Console::WriteLine( myTable->Rows[ myCell->RowNumber ][ myCell->ColumnNumber ] );
}

private void PrintCellRowAndCol()
{
   DataGridCell myCell;
   myCell = DataGrid1.CurrentCell;
   Console.WriteLine(myCell.RowNumber);
   Console.WriteLine(myCell.ColumnNumber);
   // Prints the value of the cell through the DataTable.
   DataTable myTable;
   // Assumes the DataGrid is bound to a DataTable.
   myTable = (DataTable) DataGrid1.DataSource;
   Console.WriteLine(myTable.Rows[myCell.RowNumber]
   [myCell.ColumnNumber]);
}

Private Sub PrintCellRowAndCol()
    Dim myCell As DataGridCell
    myCell = DataGrid1.CurrentCell
    Console.WriteLine(myCell.RowNumber)
    Console.WriteLine(myCell.ColumnNumber)
    ' Prints the value of the cell through the DataTable.
    Dim myTable As DataTable
    ' Assumes the DataGrid is bound to a DataTable.
    myTable = CType(DataGrid1.DataSource, DataTable)
    Console.WriteLine(myTable.Rows(myCell.RowNumber)(myCell.ColumnNumber))
 End Sub

注解

DataGridCell可与控件CurrentCell的属性结合使用System.Windows.Forms.DataGrid来获取或设置任何单元格的值。 将 System.Windows.Forms.DataGrid 控件 CurrentCell 的属性设置为使 DataGridCell 焦点移动到由该控件 DataGridCell指定的单元格。

构造函数
