Gets or sets the index of an item in the DataGrid control to edit.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

abstract EditItemIndex : int with get, set 
override EditItemIndex : int with get, set

Property Value

Type: System.Int32
The index of an item in the DataGrid control to edit. The default value is -1, which indicates that no item in the DataGrid control is being edited.

ExceptionCondition
ArgumentOutOfRangeException

The specified index is less than -1.

Use the EditItemIndex property when the DataGrid control contains an EditCommandColumn to determine the index of the item selected in the DataGrid control to edit.

This property is also used to programmatically control which item is being edited. Setting this property to an index of an item in the DataGrid control will enable editing controls for that item in the EditCommandColumn.

NoteNote

The EditItemIndex property is zero based.

To cancel editing, programmatically set this property to -1.

Caution noteCaution

Text is not HTML encoded before it is displayed in the DataGrid control. This makes it possible to embed script within HTML tags in the text. If the values for the control come from user input, be sure to validate the values to reduce security vulnerabilities.

The following code example demonstrates how to use the EditItemIndex property to determine the item selected for editing in the DataGrid control.

No code example is currently available or this language may not be supported.
