DataRow.Item Property (DataColumn, DataRowVersion)

Gets the specified version of data stored in the specified DataColumn.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public Object this [
	DataColumn column,
	DataRowVersion version
] { get; 
/** @property */
public Object get_Item (DataColumn column, DataRowVersion version)

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

column

A DataColumn that contains information about the column.

version

One of the DataRowVersion values that specifies the row version that you want. Possible values are Default, Original, Current, and Proposed.

Property Value

An Object that contains the data.

Exception typeCondition

ArgumentException

The column does not belong to the table.

ArgumentNullException

The column argument contains null.

VersionNotFoundException

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]);
