public:
 property System::Object ^ default[System::Windows::Forms::DataGridCell] { System::Object ^ get(System::Windows::Forms::DataGridCell cell); void set(System::Windows::Forms::DataGridCell cell, System::Object ^ value); };
public object this[System.Windows.Forms.DataGridCell cell] { get; set; }
member this.Item(System.Windows.Forms.DataGridCell) : obj with get, set
Default Public Property Item(cell As DataGridCell) As Object

Parameters

cell
DataGridCell

A DataGridCell that represents a cell in the grid.

Property Value

The value, typed as Object, of the cell.

Examples

The following code example sets and gets the value of a cell by declaring a DataGridCell variable, setting its RowNumber and ColumnNumber values, then first changing, then returning, the value of the given cell.

void SetCellValue( DataGrid^ myGrid )
{
   DataGridCell myCell;
   
   // Use an arbitrary cell.
   myCell.RowNumber = 1;
   myCell.ColumnNumber = 1;
   
   // Change the cell's value using the CurrentCell.
   myGrid[ myCell ] = "New Value";
}

void GetCellValue( DataGrid^ myGrid )
{
   DataGridCell myCell;
   
   // Use and arbitrary cell.
   myCell.RowNumber = 1;
   myCell.ColumnNumber = 1;
   Console::WriteLine( myGrid[ myCell ] );
}

private void SetCellValue(DataGrid myGrid){
   DataGridCell myCell = new DataGridCell();
   // Use an arbitrary cell.
   myCell.RowNumber = 1;
   myCell.ColumnNumber = 1;
   // Change the cell's value using the CurrentCell.
   myGrid[myCell]="New Value";
}
 
private void GetCellValue(DataGrid myGrid){
   DataGridCell myCell = new DataGridCell();
   // Use and arbitrary cell.
   myCell.RowNumber = 1;
   myCell.ColumnNumber = 1;
   Console.WriteLine(myGrid[myCell]);
}
    
Private Sub SetCellValue(ByVal myGrid As DataGrid)
   Dim myCell As New DataGridCell()
   ' Use an arbitrary cell.
   myCell.RowNumber = 1
   myCell.ColumnNumber = 1
   ' Change the cell's value using the CurrentCell.
   myGrid(myCell)= "New Value"
End Sub
 
Private Sub GetCellValue(ByVal myGrid As DataGrid)
   Dim myCell As New DataGridCell()
   ' Use an arbitrary cell.
   myCell.RowNumber = 1
   myCell.ColumnNumber = 1
   Console.WriteLine(myGrid(myCell))
End Sub
    

Remarks

    Dim myTable As DataTable
    ' Assumes the DataGrid is bound to a DataTable.
    myTable = CType(DataGrid1.DataSource, DataTable)
    For iRow = 0 To myTable.Rows.Count - 1
       For iCol = 0 To myTable.Columns.Count - 1
          Console.WriteLine(myGrid(iRow, iCol))
       Next iCol
    Next iRow
 End Sub
