event-handling

I’m trying to obtain the HTTPContext within an Event Handler in a Document Library in MOSS, but all I have is a null value of the HTTPContext.Current, I do the same thing on a List and the HTTPContext is returned. There is a way to obtain the HTTPContext in Document Libraries to access the HTTPContext.Request method? Thanks for your help Here is the code: public class TestContextListItemEventReceiver : SPItemEventReceiver { HttpContext current; static object obj; /// <summary> /// Initializes a new instance of the Microsoft.SharePoint.SPItemEventReceiver class. /// </summary> public

I'm developing a multi tenant n-tier web application using asp.net Mvc 5. In my service layer I am defining custom events for every important action and raising these events once these actions are executed. For example Public event EventHandler EntityCreated; Public void Create(Entity item) { Save(item); ...... EntityCreated(this, item); } I intend on hooking up business rules and notifications to these events. The main reason I want to use events is decoupling of the logic and easy plug-ability of more events handlers without modifying my service layer. Question: Does it make sense using

This isn't a crucial piece of knowledge for me, but I would still like to know what exactly is happening here. This is a .NET 3.5 Web Forms application. One of the pages has 3 server-side inputs with type 'submit'. Each one of these inputs has the following JavaScript handlers assigned to them with jQuery: $('.button').mouseover(function() { $(this).addClass('hoverEffect'); }); $('.button').mouseout(function() { $(this).removeClass('hoverEffect'); }); When I run the following script (yes, this is IE specific) $(document).ready(function() { d = window.open(); d.document.open('text/plain').write

In Chapter 15 of Liang's Intro to Java Programming (7th ed.) , he introduces a program to make a (2-D) ball on a JPanel and enlarge it upon clicking enlarge/shrink buttons. I've modified the program so that it also 1) enlarges/shrinks the ball if the user clicks/option+clicks, 2) allows you to pick the color of the ball by pressing a button, and 3) allows you to move the circle by dragging it with your mouse. The last modification is what was giving me trouble for a while, because I wanted to center the ball at the beginning, but then allow the user to move the ball around with the mouse. The

I'm trying to convert the C# code from this webpage to VB. Everything seems to have converted pretty much fine using an online converter tool, but then I reach the following line: fadeOutAnimation.Completed += (sender, args) => OnFadeOutAnimationCompleted(d, hostGrid, grid); The fadeOutAnimation.Completed event produces an event with the signature (sender, args), and d, hostGrid and grid are variables local to the function containing this mysterious event handler assignment. I think I can see that the instruction on this C# line is telling the code to execute the OnFadeOutAnimationCompleted

I have an ASP.NET GridView that's bound to an ObjectDataSource (which is bound to a MySQL database). On this grid, I have 2 unbound ButtonField columns that I want to trigger server-side events. Hence I have added an eventhandler method to the GridView 's RowCommand event. In the code of said eventhandler, I need to somehow get hold of the underlying DataRow that was clicked on by the user. However, I can't seem to get this to work; if I use code like the following the selectedRow variable is always null : protected void searchResultsGridView_RowCommand(object sender, GridViewCommandEventArgs

I have a number of text boxes that are dynamically created via code. I would like to be able to assign a generic event handler to all the textboxes for the text changed even and then within the handler determine which text box has fired the event. Code I have is: txtStringProperty.TextChanged += TextBoxValueChanged; private void TextBoxValueChanged(object sender, RoutedEventArgs e) { string propertyName = // I would like the name attribute of the textbox here } Please let me know if you require anymore information. Sjoerd The sender parameter contains which control has fired the event. You can
