Exempel

I följande exempel tilldelas DataGridCell till CurrentCell för en System.Windows.Forms.DataGrid och returnerar kolumn- och radnumret för den markerade cellen. Värdet som lagras i DataTable skrivs också ut med hjälp av DataGridCell objektets RowNumber och 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

Kommentarer

DataGridCell kan användas tillsammans med System.Windows.Forms.DataGrid-kontrollens egenskap CurrentCell för att hämta eller ange värdet för valfri cell. Om System.Windows.Forms.DataGrid-kontrollens egenskap CurrentCell till en DataGridCell flyttas fokus till cellen som anges av DataGridCell.
