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
