Aaron was creating a custom web service to be used by web parts in Sharepoint, but then there was a problem of a giant list of "undefined" values returning. Done a lot of research and later this brilliant post directed us to the right place.
I wanted to use Ajax control toolkit in Sharepoint, and had not had any luck until I spent the whole day debugging and getting it to work. I already had Ajax integrated in Sharepoint, so it should be fairly easy to just add in AjaxControlToolkit, but the problem is the latest version of it actually requires you to use ToolkitScriptManager instead of ScriptManager, otherwise your control will not work and you will see a Javascript error of "Please wait while scripts are loaded".
I had to create a task dynamically in C# and assign the task to a reviewer, which is a user account. However, there was this problem of the "Assigned to" field is only read only. To do that, just create an SPFieldUserValueCollection and assign it to task item.
I needed to get SPUser object from doing a lookup using CAML query, so that I could get the user information such as email address, etc. To do that, this is the code that I used:
I had the problem of not able to debug Sharepoint in Visual Studio 2008 awhile ago, and glad that Aaron shown me how to do it by doing some tricks. What happened was the PDB file might not have been deployed to the assembly GAC.
Today I was testing the loading time of my site, which I sometimes find it slow to access especially the first time loading. I knew there are a lot of images to be loaded especially those in portfolio sections but I also found that the biggest loading item seems to be ScriptResource.axd from Ajax. It was 330kb!
Yesterday I spent the whole day finding on the Internet about how to restore the list form web part of my edit form as I accidentally deleted it and could never get it back from the Closed web parts, nor could I get it back by resetting the file to site definition in Sharepoint Designer.
Lookup field is a field which links a child class to a parent class, it is an association kind, which allows a list item to reference another item from another list. However, reading and writing to a lookup field is different from a normal field. We need to use the class SPFieldLookupValue to archieve this.
Creating Update Panel in code behind dynamically can be a bit tricky, comparing to doing it at the front end. Here's a quick view of the code we write to do this.
Just yesterday I realised suddenly I couldn't login to my Hotmail account. No matter what I tried, even the password reminder, etc didn't work. It seems as if something happened and then I realised my eBay account is not working too. Normally I would use iPhone to login to My Ebay, and strangely when I logged in via IPhone, my eBay account username was shown as someone else. Immediately I knew my accounts have been hacked.
