Özellik Değeri

Object

Hücrenin olarak Objectyazılan değeri.

Örnekler

Aşağıdaki kod örneği, bir değişken bildirerek DataGridCell , değişkenini RowNumber ve ColumnNumber değerlerini ayarlayarak, sonra önce değiştirip sonra verilen hücrenin değerini döndürerek hücrenin değerini ayarlar ve alır.

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
