multithreading - Is there a way to take a method that creates UI elements and make it cancelable? -

I have a way that is said when entering a chart page in my WP7 app. It creates a list of objects and populates a list box. Each ListBoxItem has a grid that contains 10 columns of data. This list also generates incredibly quickly with 1000-2000 items, but as soon as the method starts making the grid and adding them to the listbox, it is relatively slow. Now, this means that it only connects the device to half as a comparative app on my 2GN. ipod touch. So the display is very good - as long as the user wants a data chart

If the user hits the start button, the app gets out, so there is no problem. My concern is that when the user goes back to the previous page. The app is still waiting till the method does not run. I have a similar behavioral notice in more mainstream apps like a Kindle app but I do not have such pressure with the Marketplace Store! I have a progress bar which keeps moving, so the behavior is the same.

Concerned by the marketplace's disapproval, I tried to put this method in a backgroundworker process but it fails because it is in the form of UI elements. This is where the obstacle exists and that I'm getting access errors so the UI is running on the thread. Is there a way to create UI elements, such as a grid, and it can be canceled?

Are you making every ListBoxItem manually in the UI element in the code ? If so, you will increase its performance by using the database because ListBox item uses VirtualizingStackPanel as a container, so it is actually enough for elements UI elements will be created and other elements are created when the user starts scrolling to scroll quickly. The Windows Phone is a great post on the Silverlight for the performance team.

If the dataset is particularly large, then you can get better performance by posting it in your post as Data Virtualization (or instead of its) < / Html>

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
