I'm trying to get the Children of an Icontent object.
IContent filialsParent = cs.GetById(filialParrentId);
if (filialsParent != null)
{
IContentService contentService = Umbraco.Core.Composing.Current.Services.ContentService;
bool hasChildren = contentService.HasChildren(filialsParent.Id);
long totalChildren;
IEnumerable<IContent> children = contentService.GetPagedChildren(filialsParent.Id, 1, 100, out totalChildren);
foreach (var child in children)
{
context.WriteLine(string.Format("child: {0}", child.Name));
}
context.WriteLine(string.Format("Children found:({0}) in: {1}", children.Count(), filialParrentId));
}
If I debug the code, I get the following.
My long totalChildren will be 1 after the line contentService.GetPagedChildren(filialsParent.Id, 1, 100, out totalChildren); runs.
My IEnumerable<IContent> children is null, and for that reason (of course) is my children.Count() 0
Sadly filialsParent does not contain the function .children() as I hoped it would.
Is there a way to get the Children of my filialsParent, and yes it does have children that are published.
I dit got the exact same problem. For testing purposes I removed everything Only bare essentials.

Make sure you got a parent and a few childeren attached
// For testing purposes hardcode your parent Id
var contentId = [ID];
// SET for returning total records
long totalChildren;
// int id ==> You even could hardcode your first param (contentID in here)
// long pageIndex ==> SET your index to 0 ==> first indexpage starts at 0 and not 1 ==> if you set this to 1 and the Pagesize = 100 and you have only 99 childeren you wil wil get null because we are requesting the second page
// int pageSize ==> We need max 10 childeren
// out long totalChildren
// IQuery<IContent> filter = null ==> not used
// Ordering ordering = null ==> not used
IEnumerable<IContent> children = Services.ContentService.GetPagedChildren(contentId, 0, 10, out totalChildren);

I am trying to count all elements within a Skip list without having to know the type of the element contained within it.
like this:
Module mod = current()
Skip skip = create()
put(skip, 1, "test")
put(skip, 2, mod)
print count(skip) // Returns integer
As far as I know, DOORS does not support this natively. To create this functionality I took advantage of an odd loop behavior where the object in a loop doesn't get assigned until you actually use it:
int count(Skip skip)
{
if(null skip)
return 0
int i = 0
// Doesn't get assigned unless you do something like obj = obj within the loop
string obj = null
for obj in skip do
{
i++
}
return i
}
im making a SortedLinkedList, I'm trying to add lets say 10 integers of different value so I can run some asssert tests. But I'm having a problem adding them so they are already sorted when they arrive to the LinkedList, I tried using the curr.info.compareTo(x) > 0 for instance, but I'm having trouble making the correct else/if statements so it sorts them when they are added.
This code has 4 classes, I can provide more if its unclear.
Thank you for your help in advance.
Best regards,
Victor
public class SortedLinkedList<T extends Comparable<T>> implements Iterable<T> {
/* Easy operations for a linked list
add(x): Searching for the place where the element x is to be added must
take place in the calling routine. This must set previous to
point to the node AFTER which the new element is to be inserted.
curr is set to point to the new element.
remove(): The curr element is removed from the list. Searching for this
element must take place in the calling routine. This must set
curr to point to the element to be removed. After removal curr
points to the element following the removed one.
isEmpty(): checks for an empty list
endOfList(): checks whether curr has reached and passed the end of the list
retrievecurr(): return the info part of the curr element.
reset(): resets the list so that curr points to the first element
succ(): an iterator, moves curr one step forward
Note that when a class implements the interface Iterable<T> then
it can be the target of the "foreach" statement. See IterationExample.java */
private Node start, curr, prev;
public SortedLinkedList() {
curr = null; // the curr position in the list
start = null; // the first element
prev = null; // the node before curr
}
public void add(T x) {
if (start == null) { // if start == null, insert a first element into an empty list
Node newNode = new Node(); // create the new element, info and link are set to null.
newNode.info = x; // and assign the data given as parameter. The link is left as null
start = newNode; // start is updated to point to the new element

prev.link = newNode; // ... and after previous

I'm using context.Database.ExecuteSql to update a table. The update with where clause is executed correctly and the record is updated. However the method returns 2 for rowcount instead of 1. When I execute the update statement in SSMS, the result rowcount returned is 1. Can someone provide insight on this?
string query =
string.Format("update {0} set Description = '{1}', Code = '{2}', LastUpdatedBy = '{3}', LastUpdatedDate = '{4}' where ID = {5};",
tableName,
description,
code,
lastUpdatedBy,
lastUpdatedDate,
ID);
int rowCount = 0;
string message = string.Empty;
using (DBContext context = new DBContext())
{
rowCount = context.Database.ExecuteSqlCommand(TransactionalBehavior.EnsureTransaction, query);
}
return rowCount == 0 ? //this return 2 instead of 1.
new SaveResult(SaveResult.MessageType.Error, string.Format("There was an error updating a record in the {0} table.", tableName), "Index") :
new SaveResult(SaveResult.MessageType.Success, string.Format("The update of {0} was successful.", tableName), "Index");
This returns rowcount = 1 in SSMS:
update zAddressTypes
set Description = 'Current', Code = '101122', LastUpdatedBy = 'user', LastUpdatedDate = '10/20/2014 12:17:26 PM'
where ID = 1;
DECLARE #RowCount INTEGER = ##ROWCOUNT;
select #RowCount;
The rowcount is being returned separately. What you are seeing here is the exit status of the query.
ExecuteSqlCommand return value is for the status of query not for row count. You may want to look into using a datareader or something similar to return the rowcount.
It is the way the datacontext works, see this link:
Entity Framework: Database.ExecuteSqlCommand Method
Apparently the command is updating two records.
Do you have a trigger on your table? I confirmed this behavior can be caused by a trigger as the rows affected by the trigger are added to the row count affected by your SQL command. I commonly check for a 0 or >0 return value to know if anything was affected. You could also return an output variable if you're calling a stored procedure.
Hi in my shoping cart i have put a check for itemname and carttotal .
if (carttotal >'500' && itemname.indexOf("Custom") == 0)
{
//code to display popup
}
There are to situation 1 in which it works fine and other when it fails:
working condition: if i added itemname "custom" at last then its working:
E.g.:
First item in cart is anything "abc" and last itemname is "custom" and carttotal is >500.then popup display fine.
NOT WORKING CASE:if i added itemname "custom" at first and after that i added some more items like "xyz".and carttotal is >500.then popup does not display.
Your current code checks to see if Custom is the first item in the list (an index of 0). What you really want to do, to check if Custom is present anywhere in the list, is see if indexOf('Custom') returns a value that is > -1, as -1 is the failing value for indexOf(), not 0 or another falsy value. For example:
var carttotal = /* Your cart total */
var products = [ /* Lots of products */ ];
for(var i = 0; i < products.length; i++) {
itemname = products[i];
if(carttotal > 500 && products.indexOf('Custom') > -1) { // `products`, not `itemname`
// Popup
}
}
Here, I'm also checking against products, assuming that is your array of products. If itemname is, then use that.
I have site with a listgrid and a openlayers map with points. When i cklick on one of these, the application shall scroll and mark this record. This works with a standard listgrid, but with a grouped listgrid it does not work.
lg = new ListGrid();
lg.setWidth(330);
lg.setDataSource(ds1);
lg.setAutoFetchData(true);
lg.setSortField("KU_NAME");
lg.setGroupStartOpen(GroupStartOpen.ALL);
lg.setGroupByField("KU_NAME");
lg.setShowFilterEditor(true);
kuName = new ListGridField("KU_NAME", "Künstler Name",150);
// Standorte
ListGridField stdOrt = new ListGridField("STDORT_NR","Standort Nr.");
ListGridField oid = new ListGridField("OID","OID.");
lg.setFields(stdOrt,kuName,oid);
and the select:
String stdortOID = stdOrtOIDjso.toString();
ListGridRecord[] records = lg.getRecords();
int i;
for (i = 0; i < records.length; i++) {
if (records[i].getAttribute("OID").equalsIgnoreCase(stdortOID)){
break;
}
}
lg.deselectAllRecords();
lg.selectRecord(i);
lg.scrollToRow(lg.getRecordIndex(record));
the reason is that in the record is only the value of the group name and the other attributs are unavailable.
When grouping is enabled, all data are "transformed" into tree and listgrid itself contains data for groups so you have to look for your record in this tree. Replace last 3 lines with (modified) Vittorio Paternostro suggestion:
Tree tree = lg.getGroupTree();
if (tree != null) {
TreeNode node = tree.find("OID", stdortOID);
if (node != null) {
lg.selectSingleRecord(node);
lg.scrollToRow(getRecordIndex(node));
lg.markForRedraw();
}
}
Note: Instead of deselectAllRecords + selectRecord use simplified selectSingleRecord.
I had the same need and the following works fine for me. You can use getGroupTree() and search the desired property in it (column value) without worrying about grouping. Make sure you search for unique values (i.e. a unique key) to identify a precise node.
Tree tree = getGroupTree();
if (tree != null) {
TreeNode node = tree.find("property", "value");
if (node != null) {
selectSingleRecord(node);
scrollToRow(getRecordIndex(node));
markForRedraw();
}
}
