Model3DGroup slow performance on adding items

Posted By:      Posted Date: October 18, 2010    Points: 0   Category :WPF

Performance on our program struck on Model3DCollection.Add method

We often adds and removs GeometryModel3D from screen, and adding models to Model3DGroup.Children -> Model3DCollection takes 20% of performance.

Reduce the number of models addid to Model3DCollections is impossible. All objects and materials are freezed.

 Can someone helps?

It would be very useful to have a method like Model3DCollection.AddModels for adding a set of models without having to fire changed events.

Adding new items to a Repeater control with transitions?



I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. This works fine but there are a couple of requiremnts that are giving me problems and wondered if the the good people of the forum could make some suggestions.

The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions.

I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater. I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.

I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there

Very Slow Performance on 64 bit SQL System

Hello, we have a Windows Server 2008 64 bit and a SQL Server 2008 64 bit. The server work and the speed with a quad CPU and 8 GB RAM is nice. But, we use a SQL script with xml (we make a XML paket for replication) is the speed very slow. The script need 40 - 60 min to finish. But the same Database and the same script on a Server 2008 32 bit and SQL Server 2008 32 bit on the same hardware need 22 seconds. We have all updates installed. Have anywere a Idea? Thank

Adding items to ObservableCollection via DataGrid

Hi All, I have a DataGrid bound to an ObservableCollection. I'd like to be able to add objects to the collection via the Grid. When I was working with sample data, I could go to the bottom of the grid, hit enter and add a new entry. Now that I'm using real data I don't seem to be able to do that. I tried taking a look at the class that the SampleData creates and can't quite fathom what it's up to. Does anyone know what I'm missing \ what I need to implement to make this possibe? Thanks Warrick

Adding, removing or editing the items of combobox.....

Hello everyone, I am working on this application which requires Items of the combobox added, edited or removed by the end user in the different section of the application such as settings window or something like that. I guess If we bind the Combobox to the database where we could easily add , remove or edit the items of combox but for the application that doesn't use database that creates a lot of overhead. To demonstrate that Here is my sample application Window1.xaml <Window x:Class="MySampleApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib" Title="Window1" Height="300" Width="300" xmlns:local="clr-namespace:MySampleApplication" ResizeMode="NoResize" WindowStartupLocation="CenterScreen"> <Window.Resources> <local:StringsLenToBooleanConverter x:Key="mvc"/> </Window.Resources> <Grid> <ComboBox Height="26" Margin="12,75,12,0" Name="comboBox1" VerticalAlignment="Top"> <s:String>Red</s:String> <s:String>Blue</s:String> <s:String>Green</s:String> </ComboBox> <Button Height="28&quo

Slow performance when searching in "any part of field" of a SQL Server database using a Microsoft Ac

We have just migrated our back end database from Access to MS SQL Server 2008 R2. We have noticed better performance on our searches - unless we select to search in "any part of field" in Access (with Access' built-in search function - we use a mix of Access 2003 and 2007). This takes nearly 20 seconds to find the result, whereas before the migration it was taking 5-7 seconds (compared to instant results we now experience when searching for whole fields). The main fields we search are not large - usually just two words. Obviously it is better to search for a whole or start of a field, but this is not always possible. The contractor that assisted us in this project has told us that this "is just the way SQL works with Access". Is this really true? I find it hard to believe two MS products would have such a big issue between them. I presumed using SQL with an Access front end would be a common setup, which is why I thought this must be a problem with our setup. Is there any way to fix this speed issue?

Very slow performance with a query involving JOINS

I am experiencing extremely slow performance on a particular SQL query using SQL compact.  This same query completes in less than one second on my regular SQL server.  With SQL compact, I am actually not even sure if the query ever completes.  As I type this I am testing it from SQL management studio, and it's up to 17 minutes and 40 seconds still executing so far. Since I am not experiencing this on most of my other queries, I have little doubt the slowness is due to the volume of data in these tables, coupled with the fact that I am doing the joins.  I made sure that foreign key constraints are in place for the columns that the joins are based on.  From what I've read, this also ensures that appropriate indexes are created, although I am starting to wonder about that. This is the query: SELECT TOP (200) t.BusinessEntityID, t.BusinessName, t.IsTowTruck, t.IsHospital, t.TowTruckLastUsed, t.BusinessLocked, cn.Address1, cn.City, cn.State, cn.PostalCode, cnp.PhoneNumber as TopPhoneNo, GetDate() as LastUpdatedDate, GetDate() as CreatedDate FROM tblBusinessEntity t LEFT JOIN cnBusinessEntityLocation cn ON cn.cnID in (SELECT TOP (1) cnID FROM cnBusinessEntityLocation where cnBusinessEntityLocation.Active = 1 AND cnBusinessEntityLocation.BusinessEntityID = t.BusinessEntityID

In a group calendar, can items be made visiable to all users by default without adding them as atten

Well the title says it all really. We have a functioning sp 2010 site, setup this weekend, that's working great so far.  Primarily its being used for the company manual and procedures (a wiki site).  Search is working well and so on. I added a calendar with the intention of showing key company activities, plus holiday information and who's out at meetings.  We're a small company and this is unlikely to get ridiculously except on exceptional days. As it stands, when i create an item (for example someone out for a weeks holiday) unless another user adds one of the 'attendees' of the holiday event to the calendar it doesn't show up.  If I add all users as attendees then they can all see it by default. However, if I show that our chairman is attending a meeting at a client, then I can't explicitly say that the chairman is an attendee because for everyone to see it, they have to be attendees as well. I nsoed around a little and thought target audiences might be the way to go.  I configured all users and manager relationships, compiled the audience (it shows the right number of users).  However, if I setup a meeting with the chairman as an attendee, and the whole company audience as the target audience, then people still can't see it. Back to square one. So, is there an actual answer to this?  A different type of calendar, a query that

MDX query performance is slow for complex logic implementation in Calculated Members.

We have implemented a calculated members which involves multiple calculated members  called in a nested e.q. Cal1 calls Cal2 and Cal2 calls  Cal3  and Cal3 calls Cal4 .  And when browing Cal1 through Excel it takes around 30 mins for getting result from a Partition having row count around 5 million. Follwing are the information on the scenario I am having: We are having partitioning in the cube. one partition contains around 4-6 million records Processers on Query Server: 4 quad core RAM on the Query Server: 64 GB Calculated members having simple calculation logics are giving results in no time. There is a Calculated members which calls 6 intermediate calculated in nested way and with small Data Set like 5-6 k rows it is running fine.   Any help will be much appreciated.   Regards, Sandeep

Slow Replication Performance

I have a fairly large table and I have updates 1.2 million rows on the Primary. The replication performance is very slow. There is a text column on this table. I am using profiler to see the performance on the target end. It says CPU time is @200ms and Duration is @210ms. The number of locks acquired on this table is very high. There is not much going on the target end. I cloned this table and performed an update on one row and it takes just 12ms. I am not sure what is going on. Any pointers to improve performance will help!  

CAST in delete query-Performance is so slow

Hi all, I've below join in the delete statementt, but it's taking so long the query run, the performance is really bad because of cast conversion, is there a better way, especially performace wise to fasten this below join, A.PHONE in nvarchar data type and DNC.PHONE_NUMBER  is in bigint data type.   A.PHONE=CAST(DNC.PHONE_NUMBER as varchar (15)) Thank you.

IE9, Site Specific Browsers, and adding your own Jump List Items to Pinned Tabs

Site Specific Browsers aren't a really new idea. In 2005 there was an app called Bubbles I ran for a while that would let you run a website with minimal "browser chrome." Mozilla Prism (né WebRunner) is a Firefox add-in that does a similar thing. Google Chrome includes the idea of Application Shortcuts. The idea of all this is that some web apps are really applications and you think about them as applications. For me, I think of Gmail and Facebook and Twitter and Basecamp as applications not necessarily as browser tabs. The notion of Site-Specific Browsers is definitely arriving. Internet Explorer 9 Beta (IE9) is out now and includes a featured called " Site Pinning " which is a effectively Site Specific Browsers. It's...(read more)

Problem when adding items to a listbox from different threads


I have an application in which different threads add items to a listbox throughout the application's execution (not at startup). But when one of the threads tries to add an item to the listbox, a System.InvanlidOperationException is thrown and the error message is: "The calling thread cannot access this object because a different thread owns it." (In my scenario the "calling thread" is one of the worker threads that add items to the listbox, and the "different thread" is the UI thread.)

So basically I just need a simple way to allow the threads to share the listbox object, or, failing that, some other workaround.

Slow performance of WCF service calling singleton (which calls COM+!)


WCF Service call routing to COM+ application.
netTCPBinding, throttling set pretty high.

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Multiple)] 

Service has two methods, one simply returns the string was input, the other calls the COM+ component and FOR TESTING returns the string "success" for every call. Therefore, both methods return a simple string.

Client starts 20 threads, each calling the WCF Service twice. (NOTE: A "first call" is made to prime the singleton service and also the COM+ component)

adding mor tables to datasource view causes writeback performance problems


I've got a very strange behavior in one of our SSAS databases. We had performance issues so i've tried to put only the essential parts into one OLAP Database

the result is:

Just by adding more tables to the datasource view the writeback performance drops from 0,2sec to 3 sec. No changes to the cube, no changes to the dimensions.
The t-sql statement fired for the writeback remains the same.
Any idea?
