Hi people,

Anyone has a sample program using ShapeListBox in ASP.NET 4.0?

Thanks,

Alex

Hi,

There's the \vs2010 (dotnet 4)\Samples\CSharp\Flowcharter sample project showing the ShapeListBox. What's wrong with its rendering?

Hi Stoyan,

Well, first the ShapeListBox seems not loading correctly configured shapes from the xml file when page loads. Second, when trying to reload the shapes using the javascript, it loads, but only displays rectangular shapes without the configured images.

Anyway, will check the sample you mentioned. If you can shed some lights on this one, I'll appreciate it.

Thanks,

Albren

Hi, Where can I also find sample xml file being assigned to ShapeListBox.ShapeLibraryLocation?

Thanks,

Albren

Here's a small example that loads a shape library file:

If your custom shapes have some images associated with them, check your web server logs to see if the applets tries to GET them from the location you actually keep the files. If the images are specified through relative paths instead of full URLs, I think the applet will try to load them relatively to the jar location instead of the html page location, so be careful if the applet is not in the same folder as the aspx file.

I hope that helps,
Stoyan

hi, in my library file, this is what I've got. <image x="0" y="0" width="100" height="100" src="/images/Campaign/Test.png" />

the folder images is a sub-folder from the main web-site folder.

Is this correct?

I have also below the snippet of how the ShapeListBox is declared in the aspx file.

<ndiag:ShapeListBox ID="CampaignElements" runat="server"
            Style="left: 480px; width: 160px;
            position: absolute; top: 0px; height: 320px;
            background-color: white"
            ShapeLibraryLocation="/CampaignShapeLibrary.xml">
        </ndiag:ShapeListBox>

Thanks,

Alex

Hi,

I think setting ShapeLibraryLocation="/CampaignShapeLibrary.xml" will look for the xml file in the root folder of the server file system if you are using ImageMap mode. You'd have to use Server.MapPath and set the location from code-behind if the xml file is at the root folder of the site.

If you are using JavaApplet mode, you should add ClientSideMode="JavaApplet" to the aspx code shown above. I think the applet will look for the xml file at the root of the site then.

I hope that helps,
Stoyan

Hi,

I now manage to bring up the rectangular shapes, but it's not showing the images. I have this src="\images\Campaign\Toolbar_EmailMessage.png" /> in my xml file. Is this correct?

Thanks,

Albren

Are these images available in a yoursite.com/images folder? The applet will look for them there if you have a leading slash in the src value. If the images folder is relative to the applet, try removing the first slash: src="images/Campaign/Toolbar_EmailMessage.png".

I hope that helps,
Stoyan

Hi,

Got another issue, well, the images are being rendered now properly, however, when I drag an item to the Diagram, I do not get the right Argument from the RadAjaxManager1_AjaxRequest eventhandler.

Any idea?

Thanks.

Hi,

RadAjaxManager is a Terlik's component as far as I know, NetDiagram won't raise events of a RadAjaxManager1_AjaxRequest type.
