Asp. NET page Pop-up window method

Because the project uses the pop-up window, or is called the simulation window, this time has studied, the solution many, for instance, window.open (), Window.showdialog (), uses the layer simulation, the frame +div+javascript ....

With window.open (), the disadvantage of this method is that it will be blocked by the browser or related software. With layer simulation, if you want to implement a more complex window, it is more difficult, the third method is to synthesize all the knowledge of Web page production, can provide a good solution. However, the third implementation is difficult to accomplish for people who don't have enough knowledge of JavaScript. Some time ago in the online shopping, found a good solution: Greybox. After repeated research, it was found that Greybox can almost complete all pop-ups (although it seems to be less supportive of frames in the framework). For ease of use, I encapsulate greybox as a control. Now paste the usage out:

1. Documents involved: GreyBox.dll (Dynamic Library) Greyboxloader.aspx,greyboxloader.aspx.cs (frames for loading web pages), GB_STYLES.CSS (style sheet)

2. Add Files:

① Add references GreyBox.dll to Bin folder

② add Greyboxloader.aspx,greyboxloader.aspx.cs to the project's root directory.

③ add gb_styles.css file to imges/css/folder

3. Call Method:

① Reference Control:

Add code at the top of the page: <%@ Register assembly= "Greybox" namespace= "Greybox" tagprefix= "CC1"%>

To add code between <form></form>: <cc1:greybox id= "Geybox1" runat= "Server" ></cc1:GreyBox>

② Load CSS File:

Htmllink Myhtmllink = new Htmllink ();

Myhtmllink.href = "Images/css/gb_styles.css";

MYHTMLLINK.ATTRIBUTES.ADD ("rel", "stylesheet");

MYHTMLLINK.ATTRIBUTES.ADD ("type", "text/css");

PAGE.HEADER.CONTROLS.ADD (Myhtmllink);

③ Register Popup event (take button as an example):

This. BUTTON1.ATTRIBUTES.ADD ("onclick", "Return Gb_showcenter" (' Modify password ', ' echangepw.aspx ', 200,390) ");

Parameter description of Gb_showcenter (' title ', ' URL ', Height,width) method:

Title: Caption of pop-up window

URL: Web address or Web page filename

Height: Pop-up window Heights

Width: Pop-up window widths

In this way, click on the Button1 to pop a window.

4. Methods:

To close a window:

Response.Write ("< script language=javascript>parent.parent.gb_hide ();</script>");

To submit and close a window:

A frame of case (IFRAME)

Response.Write ("< script language=javascript>parent.parent.document.forms (0). Submit ();</script>");

No frame of case

Response.Write ("< script language=javascript>top.window.document.forms (0). Submit ();</script>");

Description: All the resources of Greybox are owned by the original author, and they are interested to visit their website. The above has a detailed introduction, of course, you can also discuss with me, I would like to share with you.

PS: Last month, the end of the release of the code generator, was intended to upload the source to friends as soon as possible, but, because recently in a project, plus that code generator for colleagues to use, found some bugs and put forward some requirements, I am ready to rewrite.
