Problem re-creating web part page

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :SharePoint


I've got some web part pages which are being setup programatically. I want to be able to refresh those pages, i.e. delete all webpart on them and recreate the content from scratch. When I try this, the following exception is thrown:

The transformer type "Microsoft.SharePoint.Portal.WebControls.TransformableFilterValuesToEntityInstanceTransformer" is not allowed to be used on this page.

The exception comes from the following line:

SPWebPartConnection newConnection = wpmngr.SPConnectWebParts(providerWebPart, providerConnection, consumerWebPart, consumerConnection, transformer);

So I thought "let's delete the page and then just recreate it". Doesn't work either, same exception is thrown. I have no idea why this code would work the first time, but doesn't work a second time. It seems like something get's stuck preventing the same action twice, but I have no clue what to look for.

How to automatically enable web part connections when creating a publishing page based on a custom p


I have created a simple custom page layout in SharePoint Designer, added a couple of web part zones, and a custom web part on each zone.

These web parts have a custom provider-consumer set of interfaces. I configured the connection between the web parts in SharePoint Designer (using Add Connection wizard), and saved the page layout.

After that, I checked in the layout and approved it in SP's web interface.

Finally, I created a Publishing Page based on my layout, but the connection between the web parts was not set. I can set the connection manually and it works fine, but I would like the connection to be automatically set on each page I create based on the layout.

Is this the expected behavior? If so, is there a way to configure the connection automatically either programmatically or declaratively?

Is there a step I'm missing?

Change part of a page without full postback


I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript, but I don't know how and would appreciate some help. Thanks!

how to add a wiki page as a web part


Hi All,

I have created a feature that generates a page and adds a content editor web part, links web part (using elements.xml). Everything works fine but I would like to replace content editor web part with a wiki page that I am going to create.

For example, I copied an excerpt from elements.xml file that adds a content editor web part for the page.

<Module Path="Dependencies/Pages" Url="">
  <File Url="default.aspx" Type="Ghostable">
   <!-- Add the Rich Content Text Editor web part -->
   <AllUsersWebPart WebPartZoneID="Right" WebPartOrder="1">
          <WebPart xmlns="http://schemas.microsoft.com/WebPart/v2" xmlns:iwp="http://schemas.microsoft.com/WebPart/v2/ContentEditor">
            <Assembly>Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c</Assembly>
            <Title>Executive Summary</Title>

 Can someone tell me how I can add a wiki page using manifest (elements.xml) file or some other way?

creating different sub page design template in sharepoint website


I know very little about sharepoint and have outsourced the design of a master page and sub page design for a new website using sharepoint. i received a site master file with all of the necessary images and the home page works just fine. However the file i received for the sub page design template was an ASPX file with the following instructions:


Here I enclosed the inner page layout file. You upload this file by using following instructions. you can change & edit the blue menu section in the master page itself. If I change into modifiable section you need to add the menu in each and every page, otherwise it will show as empty block. Please let me know your comments.

Add page numbers for paging in data view web part


Hello all,

Has anyone found a solution that will allow me to have page numbers for paging in a data view web part. For instance, if I have 40 items/rows and I set the paging to display 10 items, I'd like the paging to show 1 2 3 4 rather than showing 1-10 and having to click next over and over to get to a specific item.

I found this article, but it is for 2003 and doesn't seem to apply to 2007 or if it does I am not able to really figure out how.


Please help!

Thanks in advance.


SharePoint Calendar Error: The "ListViewWebPart" Web Part appears to be causing a problem. Index was

In one specific SharePoint calendar, on one specific week in that calendar when we select the "more items" link in the monthly view (or the expand all option) we get the following error:
The "ListViewWebPart" Web Part appears to be causing a problem. Index was outside the bounds of the array.

Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator.

If we select a different week the expand and collapse works fine in that calendar.

Problem with master page and update panel (I think)



the app I am working with is made up of three nested master pages that have the following design:

The first master page ha only realize the HEADER, BODY and FOOTER divs.

The second one specialize the Body content placeholder and divide it in three more layers: NAVIGATOR, PAGE TITLE, BODY CONTENT.

The final layer specialize the BODY CONTENT in PAGE CONTENT and ACTIONS.

In one of my content pages I have (inside the PAGE CONTENT area) 

  • 1 Update Panel that contains a gridview object
  • 1 Update Panel that contains some HTML code to show in a PopupModalExtender

The PopupModalExtender can be either triggered from inside the gridView and also from a series of LinkButtons that are in the ACTIONS area.

The problem is that when the PopupModalExtender shows the FOOTER and the ACTIONS areas are not dimmed from the style I apply as background to the modal popup. An example of what I am trying to explain can be viewed in the following screenshot.

Why this is going to happen? Has anybody any suggestion on how to solve this problem?

Thanks a lot

Web Part working fine on the top-level page but 'Not Safe' error on lower-level pages.


I have created a Web Part which reads and parses the SharePoint logs in order to display usage information of the page it resides on.  The Web Part works perfectly on the top page, reading and displaying the information desired.  However, once the Web Part is added to any page lower in the site heirarchy (sub-page) the same Web Part throws the following error:

Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.
