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

Object

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

Setting this property changes the position of the DataView to the specified row.

void PrintCellValues( DataGrid^ myGrid )
{
   int iRow;
   int iCol;
   DataTable^ myTable;
   
   // Assumes the DataGrid is bound to a DataTable.
   myTable = dynamic_cast<DataTable^>(dataGrid1->DataSource);
   for ( iRow = 0; iRow < myTable->Rows->Count; iRow++ )
   {
      for ( iCol = 0; iCol < myTable->Columns->Count; iCol++ )
      {
         Console::WriteLine( myGrid[iRow, iCol] );

      }

   }
}

private void PrintCellValues(DataGrid myGrid){
    int iRow;

       for(iCol = 0;iCol < myTable.Columns.Count ;iCol++) {
          Console.WriteLine(myGrid[iRow, iCol]);
       }
    }
 }

Private Sub PrintCells(ByVal myGrid As DataGrid)
    Dim iRow As Integer
    Dim iCol As Integer
    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
