Hi everybody,

Microsoft Dynamics AX2009 supports ASP.NET development on its Enterprise Portal framework, which runs on SharePoint. In theory, it should be possible to use the Telerik user controls on this platform. However, all attempts to accomplishing this are resulting in the same error below. The Enterprise Portal uses a 'Dynamics AX User Control Web Part' to host the user control.

System.Web.HttpException: Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error. ---> System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Recently, I found a solution for this problem on a blog. It was caused by the Enterprise Portal master Page, which set some style types in the html header. This conflicted with the Telerik components, which caused the error discribed above. When these style nodes were moved to the body, the Telerik components ran without problems.

More info on, and many thanks to: http://www.aaronguevara.com/blog/?tag=/dynamics+ax

Solution:

Open the Master page (defaultax.master) from C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\DynamicsAxEnterprisePortal
-       Copy the following text (available in the HEAD)

      <style type="text/css">
        .runOnClientDisplayStyle { <%=getStyleRunOnClientDisplayStyle()%> }
        .runOnBrowserDisplayStyle { <%=getStyleRunOnBrowserDisplayStyle()%> }
        .runOnBrowserBorderStyle { <%=getStyleRunOnBrowserBorderStyle()%> }
    </style>
-       Paste it under <BODY
-       Remove the Styles entry from the HEAD.

However, there still is a small issue when using the Telerik RadTreeView component on Enterprise Portal, the component aligns all of it's 'branches' entirely to the left and does not show any nodes, making it useless from a graphical perspective. It runs perfectly however on a regular SharePoint site.

Hi, thank you for your reply.

As requested, the declaration of the Tree View Component is shown below.

The screenshots attached are the result I get when using the RadTreeView in a Dynamics AX User Control WebPart. Screenshot1 shows the error. Screenshot2 shows what it should look like. I presume it has something to do with the Dynamics AX Web Part, as it does work on a 'regular' web part.
