Add Silverlight application in Sharepoint 2010

Microsoft SharePoint 2010 comes with an out of the box Silverlight webpart which helps to host Silverlight applications in SharePoint. For hosting the Silverlight application you need to provide the URL of the Silverlight executable in the URL property of the webpart.




You can also pass the parameters to the Silverlight application using InitParams property.



You need to implement the Silverlight application such a way that it can accept and use the InitParams, which can be consumed in Application_Start event.


private void Application_Startup(object sender, StartupEventArgs e)
{
IDictionary parameters = e.InitParams;
foreach (KeyValuePair parameter in parameters)
{
Console.WriteLine("{0} - {1}", parameter.Key, parameter.Value);
}
}

How to access SharePoint List Items using Silverlight Object Model

In the last postI introduced the Silverlight Object Model, which helps to access the SharePoint objects directly from Silverlight. In this I am posting about how to access SharePoint List Items using Silverlight Object Model. In this I am using Caml query object, which is used to get the Fields.

using Microsoft.SharePoint.Client;


private List list;
private ListItemCollection listitem;

public MainPage()
{
InitializeComponent();

ClientContext spContext = new ClientContext("http://pct174:10972");
if (spContext != null)
{
List list = spContext.Web.Lists.GetByTitle("Custom List");
listitem = list.GetItems(CamlQuery.CreateAllItemsQuery());
spContext.Load(listitem);
spContext.ExecuteQueryAsync(new ClientRequestSucceededEventHandler(OnRequestSucceeded), new ClientRequestFailedEventHandler(OnRequestFailed));
}
}

private void OnRequestSucceeded(Object sender, ClientRequestSucceededEventArgs args)
{
Dispatcher.BeginInvoke(FillList);
}
private void OnRequestFailed(Object sender, ClientRequestFailedEventArgs args)
{
MessageBox.Show(args.Message);
}

private void FillList()
{
var lst = new List();
foreach (var i in listitem)
{
lst.Add(new listdata
{
Title = i["Title"].ToString(),
EmployeeName = i["Employee_x0020_Name"].ToString(),
Gender = i["Gender"].ToString(),
DOB = ((DateTime)i["DOB"])
} );
}
And if you don’t want all the columns or you want to specify the columns you want to access you can use Caml Query object’s ViewXml property.?


CamlQuery camlQuery = new CamlQuery();
string query = "";
camlQuery.ViewXml = query;
this.oListItems = this.oList.GetItems(camlQuery);

You can access Custom Lists and Document Libraries by this method.

How to Debug a Web Part for SharePoint 2010

The basic steps are as follows:



1) Open the solution with the web part(s)
2)Copy the assembly (after it has been built) to the bin directory of the WSS web site and be sure to include the.pdb files
3) Deploy the web part (copy to the bin with the pdb as above, import the part into the web part gallery so it is visbile, create a smaple page and add the web part to the page in design view and publish the page)
4) Place a break point on the code of interest in Visual Studio
5) Under the Debug Menu, select Attach to Process
6) Find the w3wp.exe process. If none exists, begin browsing to the site that has the web part you are debugging. (I usually conduct an IIS reset so that all of the w3wp.exe processes go away and the sole one that you are interested in is easier to find)
7) Watch as the page processes and as soon as your web part is hit, Visual Studio will load symbols and begin the debugging process

Hopefully now, rather than climbing thorugh stack traces, Response.Write output, etc. you can conduct full-fidelity debugging and shave days off of a task that would only take hours.

Updating SharePoint ListItems

There are two methods available to update the List Items on SPListItem Object.
SPListItem.Update();
SPListItem.SystemUpdate();

SPListItem.Update() used to update all the values in SharePoint List Item including pre-defined hidden fields. If we modified the item, that will affects the Modified Date, Modified By, Version information fields.

SPList olist = oweb.Lists.TryGetList(“ListName”);
SPListItem olistitem = olist.Items[1];
olistitem.Title = “Sample List Item”
olistitem.Update();
olist.Update();

SPListItem.SystemUpdate() method used to update the values of the listitem without modifying the Modified Date, Modified By and Version information fields.

SPList olist = oweb.Lists.TryGetList(“ListName”);
SPListItem olistitem = olist.Items[1];
olistitem.Title = “Sample List Item”
olistitem.SystemUpdate();
olist.Update();

SharePoint's "!New" Indicator

I've had a few folks ask how to alter the amount of time the “!New” icon shows up next to a recently added SharePoint list items. I believe the default timing is set to 24 hours (That is, a “new“ item is designated for the first day it is listed).

One person asked how to simply turned it off. Another asked how to extend it to a longer period so more users are aware of new content. The answer, luckily, is the same... You need to use a command line statement. The syntax is below.

Note a few thing:

1. To turn off the “!New” icon, set the number of days to zero

2. The change is for ALL list items (not just documents) on the virtual server

3. The change is immediate and does not require an IISRESET


Run the following (you may need to navigate to the directory where stsadm resides):

stsadm.exe -o setproperty -pn days-to-show-new-icon -pv ## -url [Your Virtual Server's URL]

where ## is the number of days to show the “!New“ icon
