While
working with SharePoint 2010 one of my fried came across a scenario where he
needed to modify the home page of team site using a feature. Feature should
delete the existing content in out of the box team site’s home page and add new
web parts.
Though
this sounds very simple in first shot but practically little tricky, that’s
what I experienced.
SharePoint
2010 has come up with new features and one of them is modification in team
sites. If you observe that when a new out of the box team site is created,
there is no default.aspx instead default page is replaced by Home.aspx.
Home.aspx is a wiki page and resides in the Site Pages library of team site.
As
this is a wiki page so it’s good that this supports direct editing and you can
add web parts directly in the rich text area using UI. But when it comes to
adding web parts to this page programmatically then problem begins.
Waldek Mastykarz has given excellent workaround
to this problem where he has shown how to add a web part in Publishing Page
Content of publishing page. We can use
similar technique to add web parts to wiki page as well, only difference is of
field name of wiki page.
In the
example I have added two list view web parts in Home.aspx page , one reside at
left and other one is at right of page. This can be done with simple HTML
markup where <td> and <tr> are defined with certain widths.
In my
case Ultimate output should be like this HTML
//<div
class=\"ms-rtestate-read ms-rte-wpbox\"
contentEditable=\"false\">
// <table id=\"layouts table\"
style=\"width:100%\">
// <tr style=\"vertical-align:
top;\">
// <td style=\"width=66.6%\">
// <div
class=\"ms-rtestate-read {0}\"
id=\"div_{0}\"></div>
// </td>
// <td
style=\"width=33.3%\">
// <div
class=\"ms-rtestate-read {1}\"
id=\"div_{1}\"></div>
// </td>
// </tr>
// </table>
//</div>
In
example above {0} and {1} would be replaced by GUIDs of web parts.
I have
tried this with console application for POC but one can add this in feature
receiver.
using (SPSite site = newSPSite("http://yoursite/"))
{
using (SPWeb _web = site.OpenWeb("/yourteamsite"))
{
SPList
_list1 = _web.Lists.TryGetList("List1");
SPList
_list2 = _web.Lists.TryGetList("List2");
SPList
_sitePages = _web.Lists.TryGetList("Site
Pages");
SPFile
_file = _web.GetFile(_web.Url + "/SitePages/Home.aspx");
if
(_list1 != null&& _list2 != null)
{
XsltListViewWebPart
_list1View = newXsltListViewWebPart();
_list1View.ListId = _list1.ID;
_list1View.ViewGuid =
_list1.DefaultView.ID.ToString("B").ToUpper();
_list1View.XmlDefinition =
_list1.DefaultView.GetViewXml();
XsltListViewWebPart
_list2View = newXsltListViewWebPart();
_list2View.ListId = _list2.ID;
_list2View.ViewGuid =
_list2.DefaultView.ID.ToString("B").ToUpper();
_list2View.XmlDefinition =
_list2.DefaultView.GetViewXml();
if
(_file != null)
{
using (SPLimitedWebPartManager _mgr =
_web.GetLimitedWebPartManager(_file.Url, System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared))
{
Guid
storageKey1 = Guid.NewGuid();
string
wpId = String.Format("g_{0}", storageKey1.ToString().Replace('-', '_'));
_list1View.ID = wpId;
Guid
storageKey2 = Guid.NewGuid();
string
_liWPID = String.Format("g_{0}", storageKey2.ToString().Replace('-', '_'));
_list2View.ID = _liWPID;
_list2View.ID = _liWPID;
//Deleting
Web Parts
for (int i = _mgr.WebParts.Count - 1; i > 0; i--)
{
_mgr.DeleteWebPart(_mgr.WebParts[i]);
}
//Adding
Web Part
_mgr.AddWebPart(_list1View, "wpz", 0);
_mgr.AddWebPart(_list2View, "wpz", 1);
//Deleting
Wiki Content
_file.Item[SPBuiltInFieldId.WikiField]
= string.Empty;
_file.Item.UpdateOverwriteVersion();
string
marker = String.Format(CultureInfo.InvariantCulture, "<div class=\"ms-rtestate-read
ms-rte-wpbox\" contentEditable=\"false\"><table
id=\"layouts table\" style=\"width:100%\"><tr
style=\"vertical-align: top;\"><td style=\"width:66.6%\"><div
class=\"ms-rtestate-read {0}\" id=\"div_{0}\"></div></td><td
style=\"width:33.3%\"><div class=\"ms-rtestate-read
{1}\"
id=\"div_{1}\"></div></td></tr></table></div>",
storageKey1.ToString("D"), _
storageKey2.ToString("D"));
_file.Item[SPBuiltInFieldId.WikiField] = marker;
_file.Item.UpdateOverwriteVersion();
Console.WriteLine("done");
}
}
}
}
}
Console.ReadLine();
}
