Processes the postback data for the HtmlInputImage control.
Assembly: System.Web (in System.Web.dll)
protected virtual bool LoadPostData( string postDataKey, NameValueCollection postCollection )
- Type: System.String
The key identifier for the control.
- Type: System.Collections.Specialized.NameValueCollection
The collection of all incoming name values.
The method checks to see whether coordinates that represent the location where the image was clicked by the user are part of the postback data for the HtmlInputImage control. If coordinates are part of the postback data, then the method registers the HtmlInputImage control with the Web page as a control that requires an event to be raised when it is processed.
The origin coordinates (0,0) are located in the upper-left corner of the image.
The method is used primarily by control developers extending the functionality of the HtmlInputImage control.
