Why Javascript works only after launching developer tool bar in IE once

Hi Friends,

This post basically talks about the strange experience which I faced in one of the applications.

Problem Statement:
In Internet Explorer, the Javascript/jQuery is not working until I open the IE Tool bar once.


Solution:
After multiple trial and errors, what I observed is, it's because of the console.log present in my jQuery file.

The console object will only be activated when the IE Dev Toolbar is opened. Prior to that, calling the console object will result as undefined. After the toolbar has been opened, the console will exist (even if the toolbar is subsequently closed), so your console calls will then work.


Hence make sure to remove any Console entries from the JS file during the roll-out of the application.

SharePoint 2010/2013 Display user information using ProfilePropertyLoader

Hi Folks,

This article talks about the best way to get the user profile properties on page.

Sometimes we come across the requirement asking to show the User related information on the page.
Generally we write code by accessing User Information list to get the User related data.

In such cases, rather than writing code SharePoint gives us the provision to read the User data.

SharePoint has something called "ProfilePropertyLoader" control which will be available in any SharePoint page which has the below register tag.

<%@ Register Tagprefix="SPSWC" Namespace="Microsoft.SharePoint.Portal.WebControls" Assembly="Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Follwing are the tags we need to add to the page inoder to read the current user Name and Email.

User Name
The first line below is needed to load and make the profile properties available.

<SPSWC:ProfilePropertyLoader runat="server"/>

<SPSWC:ProfilePropertyValue PropertyName="FirstName" ApplyFormatting="False" runat="server" ShowPrivate="True" PrefixBrIfNotEmpty="False"/>

<SPSWC:ProfilePropertyValue PropertyName="LastName" ApplyFormatting="False" runat="server" ShowPrivate="True" PrefixBrIfNotEmpty="False"/>

Email
<SPSWC:ProfilePropertyValue cssClass="loggedin" PropertyName="WorkEmail" ApplyFormatting="False" runat="server" ShowPrivate="True" PrefixBrIfNotEmpty="False"/>

SharePoint site performance improvement techniques - SharePoint2010/2013 and SharePoint Online

Hi Friends,

In this article we will talk about the Steps to Optimize SharePoint Performance.

This article covers some of the factors which plays a vital role in the performance of the SharePoint site on a high level.

1)    Code optimization

•  Server side code - Use optimized methods, SPDisposeCheck etc.,

Poor Performing Methods and Properties	Better Performing Alternatives
SPList.Items.Count	SPList.ItemCount
SPList.Items.XmlDataSchema	Create an SPQuery object to retrieve only the items you want.
SPList.Items.NumberOfFields	Create an SPQuery object (specifying the ViewFields) to retrieve only the items you want.
SPList.Items[System.Guid]	SPList.GetItemByUniqueId(System.Guid)
SPList.Items[System.Int32]	SPList.GetItemById(System.Int32)
SPList.Items.GetItemById(System.Int32)	SPList.GetItemById(System.Int32)
SPList.Items.ReorderItems(System.Boolean[],System.Int32[],System.Int32)	Perform a paged query by using SPQuery and reorder the items within each page.
SPFolder.Files.Count	SPFolder.ItemCount

• CSOM - Keep ExecuteQuery function call as less as possible.

Also request properties whichever required. Ref below example

var userObj = clientContext.Web.CurrentUser;

clientContext.Load(userObj, user => user.Title, user => user.LoginName);

• Use caching in Code (Both CSOM and Server Side). Use the cache duration depends on how often the block of code changes the data.

2)    Merge JS files to single wherever possible.

3)    Make JS files to minified (min) files.

4)    Reduce the usage of global variables in JS files.

5)    Merge CSS files to single wherever possible.

6)    Use CDN(Content Deployment Network) deployment of JS, CSS and Images.

Note: Using CDNs only makes sense in a SharePoint Online context and should be avoided with SharePoint Server.
