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

protected virtual bool LoadPostData (
	string postDataKey,
	NameValueCollection postCollection
)
protected boolean LoadPostData (
	String postDataKey, 
	NameValueCollection postCollection
)
protected function LoadPostData (
	postDataKey : String, 
	postCollection : NameValueCollection
) : boolean

Parameters

postDataKey

The key identifier for the control.

postCollection

The collection of all incoming name values.

Return Value

true if the HtmlSelect control's state has changed as a result of a postback; otherwise, false.

The LoadPostData method checks whether the postback data of the HtmlSelect control is different from its previous value, and if so, returns true. If the HtmlSelect control's Multiple property is false, indicating a single-selection HtmlSelect control, then the LoadPostData method checks the SelectedIndex property. If the HtmlSelect control's Multiple property is true, indicating a multiple-selection HtmlSelect control, then the LoadPostData method checks the SelectedIndices property.

The LoadPostData method is used primarily by control developers extending the functionality of the HtmlSelect control.
