	int columnIndex
] { get; set; }

When you set the property, an exception is generated if an exception occurs in the ColumnChanging event.

If this is an edit, see EndEdit for the exceptions that can be generated.

The following examples demonstrate the use of the Item property to get and set the value of a specific column index. The first example gets the value of the first column in any row that a user clicks in a DataGrid control.

private void DataGrid1_Click(object sender, 
    System.EventArgs e)
{
    // Get the DataTable the grid is bound to.
    DataGrid thisGrid = (DataGrid) sender;
    DataTable table = (DataTable) thisGrid.DataSource;
    DataRow currentRow = 
        table.Rows[thisGrid.CurrentCell.RowNumber];

    // Get the value of the column 1 in the DataTable.
    Console.WriteLine(currentRow[1]);
    // You can also use the name of the column: 
    // Console.WriteLine(currentRow["FirstName"])
}

private void SetDataRowValue(DataGrid grid, object newValue)
{
    // Set the value of the last column in the last row of a DataGrid.
    DataTable table;
    table = (DataTable) grid.DataSource;
    DataRow row;

    // Get last row
    row = (DataRow)table.Rows[table.Rows.Count-1];

    // Set value of last column
    row[table.Columns.Count-1] = newValue;
}
