PostBackOptions.ActionUrl Property
.NET Framework (current version)
Gets or sets the target URL for the postback of a Web Forms page.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.StringThe URL for the postback of a Web Forms page. The default value is an empty string ("").
The ActionUrl property of the PostBackOptions class specifies the URL for the action attribute of a Web Forms page. The ActionUrl property can be used to specify which Web Forms page to post data back to, causing a cross-page post. For more information on cross-page posting, see Cross-Page Posting in ASP.NET Web Forms.
The following code example demonstrates using the ActionUrl property of a PostBackOptions object to cause a cross-page postback if a user positions the mouse pointer on a Label control.
<%@ Page Language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> void Page_Init(object sender, EventArgs e) { string reference = Page.ClientScript.GetPostBackEventReference (new PostBackOptions(this, "", "http://www.wingtiptoys.com", false, true, false, true, false, "")); Label1.Attributes.Add("onmouseover", reference); } </script> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>ActionUrl Example Page</title> </head> <body> <form id="form1" runat="server"> <h3>PostBackOptions ActionUrl Example</h3> <asp:Label runat="server" id="Label1" > Placing the mouse pointer on this label will cause a cross-page post to occur. </asp:Label> </form> </body> </html>
