DataGrid.Item[] Eigenschaft

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

Parameter

Eigenschaftswert

Object

Der als Object festgelegte Wert der Zelle.

Beispiele

Das folgende Codebeispiel legt den Wert einer Zelle fest und ruft den Wert einer Zelle ab, indem sie eine DataGridCell Variable deklarieren, ihre Werte festlegen RowNumber und ColumnNumber dann zuerst den Wert der angegebenen Zelle ändern und dann den Wert der angegebenen Zelle zurückgeben.

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
