WPF ToolKit VSM: VisualStateBehaviorFactory makes memory when use DatePicker

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :WPF
Hi, The VisualStateBehaviourFactory in WPF Toolkit (VSM) makes memory leak when use DatePicker. In the reference path it holds the list of VisualStateBehavior instances, the VisualStateBeahvior  holds ButtonBaseBehavior and this ButtonBaseBehavior holds the CalendarButton instances. This leads the DatePicker object still alive in the memory after closing the  application that contain the DatePicker control. Try the following scenario 1. Create a window (Window1.xaml) with DatePicker control and implement the destructor for Window1  2. Then create another window (Window2.xaml) with the button to show the  Window1.xaml. 3. Now open the Window2 and click on the button 4. Now the Window1 is opened and DatePicker control displayed. 5. Close the Window1, but its destructor does not executed until close the Window2(Parent window) or it is executed after taking some time. Why? Regards, kumar

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

How to detect and avoid memory and resources leaks in .NET application

Despite what a lot of people believe, it's easy to introduce memory and resources leaks in .NET applications. The Garbage Collector, or GC for close friends, is not a magician who would completely relieve you from taking care of your memory and resources consumption.

I'll explain in this article why memory leaks exist in .NET and how to avoid them. Don't worry, I won't focus here on the inner workings of the garbage collector and other advanced characteristics of memory and resources management in .NET.

Using the WPF Toolkit DataGrid

WPF comes with a large number of built in controls, but from the beginning it has lacked something that many application developers find extremely important - a DataGrid. You can use the ListView to create something approximating a DataGrid

file upload in chunks or not buffering in memory before writing to disk?


What are the options for handling file uploads to reduce the memory footprint?  Is there a way to upload in chunks?  Is there a way to stream upload directly to disk instead of loading entire file in server memory?


UI Datepicker and web user controls



I have developed an application using the Master-Detail pattern described in this Matt Berseth article.

The only difference between Matt's article and me is that I am using a FormView object in place of a DetailsView.

Everything works fine except that the formview object, in my case it's inside a user control and I can't figure out how to use the jquery datepicker UI plugin.

I have tried to put the script block for the datepicker either in the aspx page as well as inside the user control but in both cases the calendar does not come up when the related textbox get the focus.

Any suggestion on how to work with the datepicker inside an ascx?

thanks in advance!

VWDE 2010 Won't Install Ajax Control Toolkit on XP Pro


To my displeasure I cannot find VWD2005 which at one time would generate a complete web.config for Ajax so I downloaded and installed VWDE 2010 to a clean install of XP Pro.

I've created a new tab on the toolbar for the controls but after I select the Ajax dll to add the controls to the toolbar it grinds away and then goes poof and closes down the task leaving VWD look as if I had never even created the tab in the toolbar. 


Any advice here?

Maximum memory for string ? . System.MemoryOutOfException Occurs when reading the Content of the fil



I have a C++ code which reads a file [vtk file - its similar to text file only]. and try to store it in string.

here's the code:

String^ ParallelProjectionRenderer::GetVolumeDataAsString(String^ FileName)

    vtkSmartPointer<vtkDataSetWriter> sWriter = vtkSmartPointer<vtkDataSetWriter>::New();

    String^ FileName = "D:\\Users\\...";

    char * sptName = static_cast<char *>(Marshal::StringToHGlobalAnsi(FileName).ToPointer());







    String^ result= File::ReadAllText(FileName);   [it breaks here with system.memoryoutofexception when the file size is huge]

    return result;


this code executes fine when the file size is less than 8mb.

I wanted to know whats the maximum memory allocated to the string.

As a workaround i skipped reading out in C++ code. and i tried to read the file contents in asp.net C# code and stor

Injecting parallelism into your app is easy-managed code offers things like explicit threading and a thread pool for that. Ensuring your code remains correct when run in parallel, on the other hand, is not quite so simple.
