[mapguide-users] Mapguide Integration

[Darrin Maidlow]

Hi Jamie,

 

I believe I have done something similar to what you're wanting to do.   My
application has  a header containing extensive amounts of application logic
which can interact with the mapguide viewer, and server API as needed.  Here
is some javascript that should return what you're looking for. 

 

                return
document.getElementById("iFrameID").contentWindow.GetMapFrame();

 

Now depending on where the iframe is located it can get a bit more tricky.
Putting an iframe within a user control, or another .net container (master
controls, placeholders, panels etc) will prefix the ID of the iframe with
stuff in the rendered HTML.  For example a user control called MyControl
that contains an iframe with an ID of MyIframe would render out as
MyControl_MyIframe.  To work around this, you need to setup the iframe with
a runat="server" tag, and spit out a global javascript variable that
contains MyIframe.ClientID from the codebehind.   The updated javascript
would look more like:

 

                return
document.getElementById(globalVarWithClientID).contentWindow.GetMapFrame();

 

Also - remember that the Mapguide web tier will need to be installed on
local development machines, and the server will need to be referenced
through the local web tier to prevent cross site scripting problems.

 

Hope that helps.

Hello, I hopefully someone can help me out.

 

I have been struggling to integrate MapGuide into a custom .NET web based
application we are developing. 

 

I setup MapGuide on an external server, the dotnetsamples run great and the
MapGuide server appears to be working ok. Great. All of the dev examples
reference the dotnetviewer relatively (../mapguide/mapviewernet), I am
referencing via http://mapguideserver/mapguide/mapviewernet.

 

We are using MapGuide inside of an iframe. Our application consists of
master pages, user controls, and other .net3.5 goodness.

 

The problem I am facing, is that I don't know how to reference the viewerAPI
outside of the MapGuide frames.

 

I can use InvokeScript and pass SelectionXML to another page in another
frame. But this is not really what we want to do. We want to use code
outside of the iframe to manipulate the ViewerAPI and MapGuideAPI inside of
the iframe.

 

Does anyone have experience with manipulating MapGuide from outside of an
iframe? How about setting up a robust web application with MapGuide in the
middle?

 

Thanks for reading, looking for direction,

Jamie Greenhough
