I tried in the razor page:
<div>
#foreach (var cat in Model.Categories)
{
<a asp-page="/Index?catId=#cat.Id">#cat.Name</a>
}
</div>
And in the cs file:
public void OnGet()
{
CurPage = 1;
CatId = -1;
Search = "";
HasCarousel = false;
Title = "All Products";
var queryParams = Request.Query;
foreach(var qp in queryParams)
{
if (qp.Key == "curPage") CurPage = int.Parse(qp.Value);
if (qp.Key == "catId") CatId = int.Parse(qp.Value);
if (qp.Key == "search") Search = qp.Value;
if (qp.Key == "hasCarousel") HasCarousel = bool.Parse(qp.Value);
}
But when i click the link no query parameter is added to the address and the Request.Query is empty.
What am I doing wrong? Or what is the right way to pass the query parameters to a razor page via a link?
To add query parameters to your link you can use asp-route- in your a tag.
In your case it would look like
<a asp-page="Index" asp-route-catId="#cat.Id">#cat.Name</a>
You're also making receiving the query parameters in your OnGet() harder than it has to be. You can add parameters to your method signature like
OnGet(int catId)
and they will be passed in by the query parameters.

In Silverstripe 4 I have a
DataObject 'PublicationObject',
a 'PublicationPage' and
a 'PublicationPageController'
PublicationObjects are displayed on PublicationPage through looping a PaginatedList. There is also a Pagination, showing the PageNumbers and Prev & Next - Links.
The Detail of PublicationObject is shown as 'Dataobject as Pages' using the UrlSegment.
If users are on the Detail- PublicationObject i want them to get back to the PublicationPage (the paginated list) with a Back - Link.
Two situations:
The user came from PublicationPage
and
The User came from a Search - Engine (Google) directly to the
DataObject- Detail.
I have done this like so:
$parentPage = Page::get()->Filter(array('UrlSegment' => $request->param('pageID')))->First();
$back = $_SERVER['HTTP_REFERER'];
if ((isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']))) {
if (strtolower(parse_url($_SERVER['HTTP_REFERER'], PHP_URL_HOST)) != strtolower($_SERVER['HTTP_HOST'])) {
// referer not from the same domain
$back = $parentPage->Link();
}
}
Thats not satisfying.
Question:
How do i get the Pagination - Link ( e.g: ...publicationen?start=20 ) when we are on the Detail - DataObject? How can we find the Position of the current Dataobject in that paginatedList in correlation with the Items per Page? (The Page- Link This Dataobject is on)

You can simply pass the page number as a get var in the URL from the PublicationPage. The detail() method can then grab the get var and if there's a value for the page number passed in, add it to the back link's URL.
In the template:
<% loop $MyPaginatedList %>
Click me
<% end_loop %>
In your controller's detail() method:
$pageNum = $request->getVar('onPage');
if ($pageNum) {
// Add the pagenum to the back link here
}
Edit
You've expressed that you want this to use the page start offset (so you can just plug it into the url using ?start=[offset]), and that you want an example that also covers people coming in from outside your site. I therefore propose the following:
Do as above, but using PageStart instead of CurrentPage - this will mean you don't have to re-compute the offset any time someone clicks the link from your paginated list.
If there is no onPage (or pageOffset as I've renamed it below, assuming you'll use PageStart) get variable, then assuming you can ensure your SortOrder values are all unique, you can check how many items are in the list before the current item - which gives you your item offset. From that you can calculate what page it's on, and what the page offset is for that page, which is your start value.
public function detail(HTTPRequest $request)
{
$publication = PublicationObject::get_by_url_segment(Convert::raw2sql($request->param('ID')));
$paginatedList = $this->getPaginatedPublicationObjects();
// Back link logic starts here
$pageOffset = $request->getVar('pageOffset');
if ($pageOffset === null) {
$recordOffset = $paginatedList->filter('SortOrder:LessThan', $publication->SortOrder)->count() + 1;
$perPage = $paginatedList->getPageLength();
$page = floor($recordOffset / $perPage) + 1;
$pageOffset = ($page - 1) * $perPage;
}
$back = $this->Link() . '?' . $paginatedList->getPaginationGetVar() . '=' . $pageOffset;
// Back link logic ends here
//.....

has anyone managed to add a Web Part into a Wiki page using CSOM?
Background: Home.aspx is a Wiki page and all its WPs are located in the rich text zone (in fact a "WikiField" column). Technically they are located in a hidden "wpz" web part zone and in addition to this there is always a placeholder with WP's ID in the WikiField column.
I've modified the existing server-side code seen on http://blog.mastykarz.nl/programmatically-adding-web-parts-rich-content-sharepoint-2010/ and http://640kbisenough.com/2014/06/26/sharepoint-2013-moving-webparts-programmatically-to-rich-content-zone/ into this:
using System;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.WebParts;
public class Class1
{
void DeployWebPart(ClientContext clientContext, string zone, string pattern, string position)
{
List library = clientContext.Web.GetList("/sites/site/SitePages/");
clientContext.Load(library);
clientContext.ExecuteQuery();
CamlQuery query = CamlQuery.CreateAllItemsQuery(100);
ListItemCollection itemColl = library.GetItems(query);
clientContext.Load(itemColl, items => items.Include(i => i.Id, i => i.DisplayName, i => i["WikiField"]));
clientContext.ExecuteQuery();
ListItem item = itemColl.Where(i => i.DisplayName == "Home").First();
clientContext.ExecuteQuery();
File page = item.File;
LimitedWebPartManager lwm = page.GetLimitedWebPartManager(PersonalizationScope.Shared);
string xmlWebPart = #"<webParts>...</webParts>";
WebPartDefinition wpd = lwm.ImportWebPart(xmlWebPart);
WebPartDefinition realWpd = lwm.AddWebPart(wpd.WebPart, "wpz", 0);
List targetList = clientContext.Web.GetList("/sites/site/Announcements/");
clientContext.Load(targetList, l => l.Views);
clientContext.Load(realWpd);
clientContext.ExecuteQuery();
string wpId = String.Format("g_{0}", realWpd.Id.ToString().Replace('-', '_'));
if (zone == "wpz")
{
string htmlcontent = String.Format(CultureInfo.InvariantCulture, "<div class=\"ms-rtestate-read ms-rte-wpbox\" contenteditable=\"false\"><div class=\"ms-rtestate-notify ms-rtestate-read {0}\" id=\"div_{0}\"></div><div id=\"vid_{0}\" style=\"display:none;\"></div></div>", new object[] { realWpd.Id.ToString("D") });
string content = item["WikiField"] as string;
System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex(System.Text.RegularExpressions.Regex.Escape(pattern));
if (position == "before")
{
content = regex.Replace(content, (htmlcontent + pattern), 1);
}
else
{
content = regex.Replace(content, (pattern + htmlcontent), 1);
}
item.Update();
clientContext.ExecuteQuery();
}
}
}
Everything works fine until the last item.Update() and clientContext.ExecuteQuery() are being invoked. Before the Update() the new placeholder gets properly inserted into the WikiField contents. But after the Update() the WikiField contents reverts back to its original state (!)
Note: As an alternative it is possible to add the WP into another zone (eg. "Bottom"). In this case the WP gets displayed on the page. But it has two major drawbacks: The newly created zone is not well formatted and the WP cannot be moved or even deleted.
Thanks for any input on this.
The following example demonstrates how to add web part into Enterprise Wiki page:
public static void AddWebPartIntoWikiPage(ClientContext context, string pageUrl, string webPartXml)
{
var page = context.Web.GetFileByServerRelativeUrl(pageUrl);
var webPartManager = page.GetLimitedWebPartManager(PersonalizationScope.Shared);
var importedWebPart = webPartManager.ImportWebPart(webPartXml);
var webPart = webPartManager.AddWebPart(importedWebPart.WebPart, "wpz", 0);
context.Load(webPart);
context.ExecuteQuery();
string marker = String.Format(CultureInfo.InvariantCulture, "<div class=\"ms-rtestate-read ms-rte-wpbox\" contentEditable=\"false\"><div class=\"ms-rtestate-read {0}\" id=\"div_{0}\"></div><div style='display:none' id=\"vid_{0}\"></div></div>", webPart.Id);
ListItem item = page.ListItemAllFields;
context.Load(item);
context.ExecuteQuery();
item["PublishingPageContent"] = marker;
item.Update();
context.ExecuteQuery();
}
Usage
var webPartXml = System.IO.File.ReadAllText(filePath);
using (var ctx = new ClientContext(webUri))
{
AddWebPartIntoWikiPage(ctx, wikiPageUrl,webPartXml);
}

I have created an SQL query which checks if a user owns a record in the database, by checking if the querystring and UserID return a count of 1. This is the code below, and it works absolutely fine:
#{
Layout = "~/_SiteLayout.cshtml";
WebSecurity.RequireAuthenticatedUser();
var db = Database.Open("StayInFlorida");
var rPropertyId = Request.QueryString["PropertyID"];
var rOwnerId = WebSecurity.CurrentUserId;
var auth = "SELECT COUNT (*) FROM PropertyInfo WHERE PropertyID = #0 and OwnerID = #1";
var qauth = db.QueryValue (auth, rPropertyId, rOwnerId);
}
#if(qauth==0){
<div class="container">
<h1>You do not have permission to access this property</h1>
</div>
}
else {
SHOW CONTENT HERE
}
The problem is that I need to apply this check on at least 10 different pages, maybe more in the future? I'm all for using reusable code, but I'm not sure how I can write this once, and reference it on each page that it's needed. I've tried doing this in the code block of an intermediate nested layout page, but I ran into errors with that. Any suggestions as to what would be the best approach? Or am I going to have to copy and paste this to every page?
The "Razor" way is to use a Function (http://www.mikesdotnetting.com/Article/173/The-Difference-Between-#Helpers-and-#Functions-In-WebMatrix).
Add the following to a file called Functions.cshtml in an App_Code folder:
#functions {
public static bool IsUsersProperty(int propertyId, int ownerId)
{
var db = Database.Open("StayInFlorida");
var sql = #"SELECT COUNT (*) FROM PropertyInfo
WHERE PropertyID = #0 and OwnerID = #1";
var result = db.QueryValue (sql, propertyId, ownerId);
return result > 0;
}
}
Then in your page(s):
#{
Layout = "~/_SiteLayout.cshtml";
WebSecurity.RequireAuthenticatedUser();
var propertyId = Request["PropertyID"].AsInt();
var ownerId = WebSecurity.CurrentUserId;
}
#if(!Functions.IsUsersProperty(propertyId, ownerId)){
<div class="container">
<h1>You do not have permission to access this property</h1>
</div>
}
else {
SHOW CONTENT HERE
}
I need to parse this html code using HtmlAgilityPack and C#. I can get the
div class="patent_bibdata" node, but I don'know how to loop thru the child nodes.
In this sample there are 6 hrefs, but I need to separate them into two groups; Inventors, Classification. I'm not interested in the last two. There can be any number of hrefs in this div.
As you can see there is a text before the two groups that says what the hrefs are.
code snippet
HtmlWeb hw = new HtmlWeb();
HtmlDocument doc = m_hw.Load("http://www.google.com/patents/US3748943");
string xpath = "/html/body/table[#id='viewport_table']/tr/td[#id='viewport_td']/div[#class='vertical_module_list_row'][1]/div[#id='overview']/div[#id='overview_v']/table[#id='summarytable']/tr/td/div[#class='patent_bibdata']";
HtmlNode node = m_doc.DocumentNode.SelectSingleNode(xpath);
So how would you do this?
<div class="patent_bibdata">

The page I'm trying to scrape: http://www.google.com/patents/US3748943
// Anders
PS! I know that in this page the names of the inventors are the same, but in most of them they are different!
XPATH is your friend! Something like this will get you the inventors name:
HtmlWeb w = new HtmlWeb();
HtmlDocument doc = w.Load("http://www.google.com/patents/US3748943");
foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//div[#class='patent_bibdata']/br[1]/preceding-sibling::a"))
{
Console.WriteLine(node.InnerHtml);
}
So it's obvious that I don't understand XPath (yet). So I came up with this solution.
Maybe not the smartest solution, but it works!
// Anders
List<string> inventorList = new List<string>();
List<string> classificationList = new List<string>();
string xpath = "/html/body/table[#id='viewport_table']/tr/td[#id='viewport_td']/div[#class='vertical_module_list_row'][1]/div[#id='overview']/div[#id='overview_v']/table[#id='summarytable']/tr/td/div[#class='patent_bibdata']";
HtmlNode nodes = m_doc.DocumentNode.SelectSingleNode(xpath);
bool bInventors = false;
bool bClassification = false;
for (int i = 0; i < nodes.ChildNodes.Count; i++)
{
HtmlNode node = nodes.ChildNodes[i];
string txt = node.InnerText;
if (txt.IndexOf("Inventor") > -1)
{
bClassification = false;
bInventors = true;
}
if (txt.IndexOf("Classification") > -1)
{
bClassification = true;
bInventors = false;
}
if (txt.IndexOf("USPTO") > -1)
{
bClassification = false;
bInventors = false;
}
string name = node.Name;
if (name.IndexOf("a") > -1)
{
if (bInventors)
{
string inventor = node.InnerText;
inventorList.Add(inventor);
}
if (bClassification)
{
string classification = node.InnerText;
classificationList.Add(classification);
}
}
I need to show the ID field in the Edit Form of a sharepoint list.
There is a way to do it ? I tried a calculated field and nothing.
I know that I can see the ID field in the view, and if I show as a Access Mode.
I'm using WSS3.0
You can add the ID field to the form using some JavaScript in a CEWP.
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
</script>
<script type="text/javascript">
$(function() {
// Get the ID from the query string
var id = getQueryString()["ID"];
// Find the form's main table
var table = $('table.ms-formtable');
// Add a row with the ID in
table.prepend("<tr><td class='ms-formlabel'><h3 class='ms-standardheader'>ID</h3></td>" +
"<td class='ms-formbody'>" + id + " </td></tr>");
})
function getQueryString() {
var assoc = new Array();
var queryString = unescape(location.search.substring(1));
var keyValues = queryString.split('&');
for (var i in keyValues) {
var key = keyValues[i].split('=');
assoc[key[0]] = key[1];
}
return assoc;
}
</script>
There is an alternative method that doesn't use the jQuery library if you prefer to keep things lightweight.
You can do this by creating a custom edit form quite easily. I usually stick it into an HTML table rendered within a webpart. There may be a better way of doing that but it's simple and it works.
The key line you'll want to look at is spFormField.ControlMode. This tells SharePoint how to display the control (Invalid, Display, Edit, New). So what you'll want to do is check if your spField.InternalName == "ID" and if it is, set the ControlMode to be Display.
The rest is just fluff for rendering the rest of the list.
Hope this helps.

HtmlTableRow hRow = new HtmlTableRow();
