FormView.PageIndex Property

Gets or sets the index of the displayed page.

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

[BindableAttribute(true)]
public virtual int PageIndex { get; set; }
<asp:FormView PageIndex="Int32" />

Property Value

Type: System.Int32
The zero-based index of the data item being displayed in a FormView control from the underlying data source.

ExceptionCondition
ArgumentOutOfRangeException

The selected value is less than -1.

When the paging feature is enabled (when the AllowPaging property is set to true), use the PageIndex property to determine the index of the currently displayed record. You can also use this property to programmatically change the displayed record.

NoteNote

When the paging feature is enabled, you can also use this property to determine the page number of the record displayed; however, be aware that this property is zero-based.

To determine the total number of items in the data source, use the PageCount property.

The following example demonstrates how to use the PageIndex property to determine the page index of the displayed record.
