View 1 RepliesJavascript - Register A Client-side Event Listener On A Server-side Event?
Dec 28, 2011Ultimately, what I want to accomplish is an AJAX-based messaging system. I already have a database table for messages, and an ASPX to add new messages (and declare old messages no longer relevant).
The current messaging system simply polls the server every 15 seconds, and re-pulls the current message set.
What I am looking to do is: On $(document).ready(), register an ajax callback function that listens for a server-side event (e.g., MessagesUpdated) On table insert/update, fire MessagesUpdated server-side.
This way, whenever the table is updated (or new records added), any clients listening know that new data is available and can re-poll the server then.
Ideally, I'd also like to make the new data available as an event argument (to minimize re-polling the db).
I can find references to something like this in other languages, but I cannot find any actual code examples to get me started.
Assuming this is possible to do via .Net, can anyone help get me started on this?
I'm using the 2.0 Framework. Also while I added a VB.Net tag, I can read C# reasonably well, so please feel free to post in either language.

Unable To Use Debugger During Paint Event?
Oct 14, 2009I've got a bug in my program that I can't work out, during a paint event. The only way I can think to solve it is to watch the screen being updated one thing at a time. Problem is, I've put a break in and then I try stepping through the program one line at a time, but when I go to look at the screen it's blank - probably because I'm in the middle of a paint event? Is there some way that I can get my screen to update after each command?

VS2008: Unable To Cancel Tabpanel Validating Event?
Jul 21, 2009Winforms, VS2008 I have a mainform that has 2 usercontrols: UC1 and UC2.UC1 has a treeview with treenodes. UC2 has tabControl with few tabPages. Selecting different nodes displays different details view in the TabControl's TabPages. What I need is canceling the event when the user has selected a node in the treeview, then he selects another node (i want to be able to cancel this last event:selecting another node, all depending on a certain logic)I mean: When the user is working on a tabpage in the tabControl, when he clicks on a different node in treeview (different from the currently selected node), before displaying the new node's details in the TabControl, I perform some logic, then depending on that logic, I set
e.cancel = true in the UC2 Validating event handler. (Rememebr UC2 includes the TabControl and the user, supposedly, has the focus on a control somewhere in TabControl)
But mysteriously, the event gets never canceled and the user still moves to the next node, displaying its details in the TabControl, although I set e.cancel = true.

Unable To CTRL-DoubleClick But The DoubleClick Event Has The EventArgs?
Jun 17, 2009Within my program, I'd like to allow the user to hold the CTRL key down while double-clicking with the mouse. Specifically, within the treeview control, I'd like to allow the user to be able to CTRL-DoubleClick but the DoubleClick event has the EventArgs parameter that doesn't provide any keyboard data.I'm guessing that this is possible, but I'm just drawing a blank on how to implement it.

The background color does not change to green. Why?

View 2 RepliesOverride An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?
Jul 20, 2010I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?
