Refresh certain part of page

Posted By:      Posted Date: September 08, 2010    Points: 0   Category :ASP.Net
Hey Guys. I'm writing an ASP.NET site and I was told to add a graph to one of the pages. The graph must use a third-side DOJO class to draw the graph. I'm having some problem with it. The graph tag looks something like this : <div class="graph" type="dojo.special.graph" datasource="myModel"> where the datasource for that graph is: <div class="Data" type="dojo.special.Datasource" url="myDB.json" id="MyModel">   So, this graph is fueled using the JSON file. The problem is when I want to change the JSON file to another, lets say, insead of "myDB.json" to "myASP_DB.json" problem is that when I change it (using Java Script code...something along  MyModel.url="myASP_DB.json") the graph won't refresh itself, though it's datasource does. I do understand where the problem lays - the tag is created once on pageload, so does the graph, and than it doesn't change (although the model does). What I'm trying to achieve here is that after I will change the url attribute of  "MyModel", the graph tag will refresh itself, thus causing the graph to update. How do you think I might achieve this? and am I assuming correctly that refreshing it will cause the graph to update? Thanks a lot

Refresh part of a page



I've built a page which has an update form, and above that, a photo (based on the same edit). The photo is loaded based on the selected table row being edited.

On this page, I've got a button that opens a modal in an iFrame and allows the user to update just their profile image (all works fine). But when the modal is closed, I'd like to reload JUST the photo (and not the entire page), as it will have changed.

How should I go about doing this? I assume I'll need to use some Ajax controls?

Any advice would be much appreciated.


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?

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.

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.

Of course the current version of the Web Part is in the SafeControls list on the web.config.

The Web Part was originally designed to return site activity only for the top default.aspx page and worked fine but started to fail in the manner described above once I added the following line of code to return a SPCo
