	DataColumn column,
	DataRowVersion version
] { get; }

Parameters

column
Type: System.Data.DataColumn

A DataColumn that contains information about the column.

An Object that contains the data.

ExceptionCondition
ArgumentException

ArgumentNullException

The row does not have this version of data.

The version should not be confused with the RowState property. The version argument describes the state of the data that is contained by the column relative to the column's original value.

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

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

The following example gets the current value of a clicked cell in the DataGrid control.

private void DataGrid1_Click(object sender, 
    System.EventArgs e) 
{
    DataTable dataGridTable = 
        (DataTable)DataGrid1.DataSource;

    // Set the current row using the RowNumber  
    // property of the CurrentCell.
    DataRow currentRow = dataGridTable.Rows[DataGrid1.CurrentCell.RowNumber];
    DataColumn column = dataGridTable.Columns[1];

    // Get the value of the column 1 in the DataTable.
    Console.WriteLine(currentRow[column, DataRowVersion.Current]);
}
