We’ve got an interesting requirement. We’re using a SharePoint list to store documents which are related to K2 SmartObjects. One of my colleagues is building a custom user control that’s going to show information from this SmartObjects, and associated documents. We want to allow users to

• click to add a document to our smart object entity
• upload a file to a library
• fill in some details
• automatically associate that file by a GUID

Sounds complicated? Actually, it’s not so hard! Read more »

I’ve said it before, but not quite so explicitly – it’s easiest to get query string parameters with a regular expression. I keep seeing big JavaScript functions looping through and splitting the parameters up, and that might be fine if you want to store those and use them repeatedly – but if not, regexes are your friend.

This function will the value of a parameter. If the parameter requested isn’t in the query string, it returns null.If the parameter doesn’t have a value (e.g. debug in ...&debug&...) it returns an empty string.

function GetQueryParam(parameter){
var p = escape(unescape(parameter));
var regex = new RegExp("[?&]" + p + "(?:=([^&]*))?","i");
var match = regex.exec(window.location.search);
var value = null;
if( match != null ){
value = match[1];
}
return value;
}

I was looking through the code of SharePoint’s Blank Web Part page layout, and I kept finding elements called _invisibleIfEmpty. Now, I’d noticed that some page layouts, such as the Splash page layout had borders on their web part zones which were only shown if the zone contained a web part. I was interested in how this might work. People keep asking for web parts with borders, preferrably ones with rounded corners. Read more »

I was tempted to call this “The incredible case of the bust rendering of SharePoint pages”, but it seemed a bit long, to be honest. This is a bit of a detective story (and if I’d the developer who built this in the first place, there’d be a murder) so stick with me… Read more »
