How to display XML returned by SharePoint for web parts?

阅读更多关于 How to display XML returned by SharePoint for web parts?

问题 Lately I've been doing a lot of custom styling in SharePoint by modifying the XSL used to display various web parts. Knowing what the actual XML looks like, including which elements have actual values, really helps when working in the XSL. I've discovered a way to show this XML when using Ontolica web parts, but not when I'm using the default web parts included with SharePoint. So, is there a way to do this, either programmatically or simply by adding a parameter to the URL? I could really

Pass Querystring parameter from SharePoint to Java Applet webpart

阅读更多关于 Pass Querystring parameter from SharePoint to Java Applet webpart

问题 I have a SharePoint webpart page, with a parameter in the page Querystring (in the URL), and I also have a Page Viewer webpart (which effectively IFRAME's the specified webpage), which shows a Java applet. Is there any way I can get the parameter in the SharePoint Querystring to be recieved by the Java Applet ? The reason for doing a Java applet in a webpart is to allow a file to be dragged and dropped onto the Java applet, and the parameter shows where the file would be saved in the

问题 I have following scenario: Lets say we have two different webparts operating on the same data - one is a pie chart, another is a data table. in their Page_Load they asynchronously load data from the database and when loaded place it in application cache for further use or use by other web parts.

What are some good techniques for performance testing SharePoint web parts and controls?

阅读更多关于 What are some good techniques for performance testing SharePoint web parts and controls?

问题 This is a question about performance testing specific to SharePoint web parts and controls (although standard ASP.NET methods would be applicable as well). I'm wondering what are some good techniques, considering factors such as: caching (what and when should you cache?) load balanced servers (storing state) interaction with other parts of the page (e.g. multiple JavaScript execution) measuring CPU usage for a particular control rendered page size 回答1: I recommend Visual Studio Test Suite

Properly implement a webpart with postback?

阅读更多关于 Properly implement a webpart with postback?

问题 What I'm trying to do is to create a webpart that has a textbox where you can set the value of a literal (h2) on the webpart and a "save" button that posts back and then sets the literal accordingly. This works with one huge caveat; when the page loads after the postback the literal has not been changed. However if I log what is actually set in the literal it has the new value. Also if I reload the page again (F5) it displays correctly. At first I figured it must be ViewState, so I disabled

How to open URL in SSRS report in webpart to new window

问题 I have created a report that I will embed in Sharepoint 2007 via a webpart using a report viewer. This works well and looks rather nice, however in the report I have a text field whose action is "Go To URL". When I click on the link within the webpart the link goes to the URL but it opens the URL within the webpart. Kind of ugly. There doesnt seem to be any additional capabilities/properties of the text box in the report other than setting the URL. How can I make the link/webpart open the URL
