This design not only shows you how to use ASP.NET UpdatePanel inside ModalPopup, it also shows a way of having multiple dynamically created controls that act as triggers to show ModalPopup, and the content of ModalPopup will change depending on the control that triggered the Popup. Then user can perform an action that does partial update inside the ModalPopup. You will only need one ModalPopupExtender control by using this design.

The following diagram shows how the controls are structured in the .aspx page

As you can see here, we have an UpdatePanel inside the ModalPopup, and the ModalPopup is in the another UpdatePanel along with other dynamic controls on page.

The next diagram shows the actual look of the page.

Well, I finally have some free time to play with it. I know, I am two years late on this topic. But I still wanted to see how Microsoft Virtual Earth Map Control can work together with SharePoint, so I created a control that does following tasks

1. Read saved locations from SharePoint List

Read saved locations information from SharePoint list. SharePoint list stores location items with Title, Address and Description fields.

Render all the locations stored in SharePoint list on Virtual Earth Map Control. Virtual earth Map Control is embedded in Content editor web part - there is no need to create a custom web part.

Display custom created panel control (VEMap Control) on Virtual Earth Map Control. It shows the pushpins, location Id and Titles - user click on the pushpin Id in panel control to see the corresponded location on map

2. Write to SharePoint List

Display Pushpin Information box when user click on pushpins – information box contains the custom created HTML with Text boxes and Edit/Save/Cancel action links.

Push changed value back to SharePoint list via SharePoint list web service (/_vti_bin/lists.asmx)

Recently someone asked me to troubleshoot the problem he had with the custom web service he created.

He followed the instructions from MSDN article "Walkthrough: Creating a Custom Web Service" and generated MyWebservice.asmx, MyWebservicedisco.aspx and MyWebservicewsdl.aspx files. He also made changes to contract reference and SOAP address in both disco.aspx and wsdl.aspx to provide the necessary redirection and maintain the URL virtualization.

Web service was deployed to 12\TEMPLATE\LAYOUTS in file system and can be viewed from URL http://<site>/_layouts/MyWebservice.asmx or http://<site>/<subsite>/_layouts/MyWebservice.asmx without any issues.

"Everything looks fine except..." - he said

At this stage I knew what the problem was and his description of the problem confirmed it.

"Everything looks fine except the web service function call returns an incorrect and unexpected result"

Yes, it could be the code logic errors. But I sticked to the one obvious mistake he has made. I told him that "Only deploy your custom web service files to 12\ISAPI (\_vti_bin\) folder unless you know what you are doing"

I have seen this problem many times before from different developers, third party vendor's and IT supports. They all have their own reasons (wrong reasons) for not to deploy their custom web service files to 12\ISAPI.

Why _vti_bin folder

Ishai's post - Showing "my links" on a web page has explained how you can use the QuickLinksMicroView web part to show users "my links" on SharePoint web part page.

The web part looked great when I first added it to the web part page, but it wasn't long before I discovered some of "bugs" in this web part. Bugs or by design?

I will show you what those bugs are by using following configurations: Two groups, 6 links in the first group and 3 links in the second group.

Now let's change the default "Number of rows to display" value from 10 to 2

Click Ok and see what it gets us.

1. "Show/Hide additional links" hyperlink will not work without "portal.css" CSS registration

As you can see there is a "show 4 additional links" hyperlink at bottom of the first group (Don't worry about the second group for now, I will get to that later).  Click on the link toggles the display text (hide/show 4 additional links) without change the number of displayed items in group (no actual hide or show for additional items).

The problem here is More...

In this post I am going to show you how you can setup your SharePoint site to support Microsoft ASP.NET AJAX framework and create a basic AJAX-enabled SharePoint Web Part. You can find many great articles on MSDN on how to do these and they explained in more details, but if you are looking for a way to get it up and running in 10 minutes, this is it.

An AJAX-enabled web part with update button and display current time every time when button is clicked. Loading image and text displayed during the update.

Goal

• Enabling SharePoint site with ASP.NET AJAX framework support
• Create AJAX-enabled SharePoint web part
  • with UpdateProgress control for visual feedback in browser when web part is updating
  • with AJAX request event script to hide UpdatePanel while web part is updating
• Add AJAX-enabled web part to page and see it in action
