List Item Performance – Wide Lists and Lookups

Jimmywim | development, performance, sharepoint | 3

Disclaimer: The examples shown in this post are extremely unrealistic in terms of real-life scenarios. The numbers and types of fields used in these experiments are designed purely to test the physical limitations of SharePoint. At no point is it suggested that a real-life use of such list architecture be used. If you do have lists […]

Jimmywim | sharepoint ribbon fluent ui c# | 0

This is a cross-post from the original article from SharePoint365, available at: http://sp365.co.uk/2011/09/programmatically-add-ribbon-custom-action-to-an-existing-list/ There is plenty of documentation on the web for creating Ribbon Customisations using the standard SharePoint CAML XML mark-up. This is a great dialect for creating complex customisations to the ribbon, but they only get applied on Feature Activation. What if you have […]

Intelligent Decisioning Pty in Australia are now a Critical Path Training partner, have opened up several training workshops in October, delivering training materials from Critical Path […]

Resetting Item Level Permissions Programmatically

Jimmywim | c#, performance, permissions, sharepoint | 0

As part of my series of blog posts on item level permissions, I thought I’d post a quick note on “resetting” item-level permissions on a list. This can be done using the method SPListItem.ResetRoleInheritance() on the list item in question. This will reset any item level permissions on this item to inherit from the List […]

List Item Performance – Updating Large Lists

Jimmywim | development, performance, sharepoint, sharepoint 2010, visual studio 2010 | 1

As part of my series on performance, I thought I’d look at updating large (20,000 item) lists in bulk, and what are the fastest ways to do this. I’ve gone through a few different ways of doing this, finding out where the slowness is coming from, and I present the results of the analysis in […]

Reordering Content Types Programmatically

Jimmywim | c#, development, sharepoint | 0

After this question was asked on SharePoint Stack Exchange, I thought I’d share my method of re-ordering content types in a list. Note: this isn’t the only method of doing this, see the thread on SPSE to see more (particularly the UniqueContentTypeOrder property).

private void ReorderContentTypes(SPWeb web, string listName, string firstContentTypeName)<br>{<br> SPList list = web.Lists[listName];<br><br> SPContentType cType = web.AvailableContentTypes[firstContentTypeName];<br><br> List<SPContentType> oldCTypes = new List<SPContentType>();<br><br> for (int i = list.ContentTypes.Count -1; i >= 0; i--)<br> {<br>  if (!list.ContentTypes[i].Id.IsChildOf(cType.Id))<br>  {<br>   oldCTypes.Add(list.ContentTypes[i]);<br><br>   list.ContentTypes[i].Delete();<br>  }<br> }<br><br> foreach (SPContentType c in oldCTypes)<br> {<br>  list.ContentTypes.Add(c);<br> }<br><br> list.Update();<br>}<br>

private void ReorderContentTypes(SPWeb web, string listName, string firstContentTypeName) { SPList list = web.Lists[listName]; SPContentType cType = web.AvailableContentTypes[firstContentTypeName]; List<SPContentType> oldCTypes = new List<SPContentType>(); for (int i = list.ContentTypes.Count -1; i >= 0; i--) { if (!list.ContentTypes[i].Id.IsChildOf(cType.Id)) { oldCTypes.Add(list.ContentTypes[i]); list.ContentTypes[i].Delete(); } } foreach (SPContentType c in oldCTypes) { list.ContentTypes.Add(c); } list.Update(); }

SPList.Items versus the SPQuery

Jimmywim | c#, development, object model, sharepoint | 0

So you’ve embarked on writing a bit of code that must enumerate a SharePoint List’s Items one by one and do some stuff with them. You’ve (at some point) came across the Best Practices page on MSDN on Handling Large Folders and Lists, and seen that using SPList.Items is bad. It’s bad because you could […]
