HtmlSelect.RequiresDataBinding Property

Gets or sets a value indicating whether the HtmlSelect control needs to bind to its specified data source.

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

protected bool RequiresDataBinding { get; set; }
<asp:HtmlSelect RequiresDataBinding="True|False" />

Property Value

Type: System.Boolean
true if the control needs to bind to a data source; otherwise, false.

The HtmlSelect control uses the RequiresDataBinding property to determine whether the control needs to call the DataBind method to bind to its specified data source.

Each time the set accessor is called on either the DataSource, DataSourceID, or DataMember property to change the data source after the OnInit method has already been called, ASP.NET automatically sets the value of the RequiresDataBinding property to true. The value of the RequiresDataBinding property is also set to true when the OnDataPropertyChanged method is invoked.

ASP.NET automatically sets the value of the RequiresDataBinding property to false immediately after the DataBind method has been called.
