So, I have a grid inside a listbox. The purpose is that when the listboxitem is selected, I want the grid to show, having the selected item expand to show more detail information. I set up a style trigger for this and it works great, except for one thing: the labels and textblocks styles are unapplied on the grid. I'm assuming this ha...
I have a boolean global variable that is set true if an administrator is logged in and wants to amend the content of the lists and comboboxes. As a result, a button is displayed beside each combo to display a dialog box when clicked. If I was not coding for WPF, I would probably include some sort of code similar to the following in each...
How do I disable a specific node so the user can not select it. Hiding it for the user is also valid. I tried the Visible property but that hides the entire tree (all nodes). I only want a few of the nodes disabled/hidden. C# using Visual Studio 2005 TreeNode Editor. ...
I want to call a javascript function when a div is turned from "visibilty : hidden" to "visibility : none;" Also note that I don't have control over the script which turns this style property of the div. I just want to hook into this. Any possibilities? Or like onFocus() etc? UPDATE : I do not want to use JQuery or other frameworks. Is...

Is there a way I can configure my asp.net web service to work with only some applications? In other words, I am saying "only these applications have access to this web service and can therefore use it. Others can't". When other applications tries to discover the service, it shouldn't even show up, or at least it should conceal it web me...
I'm curious how I can create a DIV (or anything really) that I can fade (or change opacity of) when a user scrolls down the page. This DIV would sit at the top of the page, but only be clearly visible when at the very top of the page. Additionally, it would be ideal if I I could have this element fade back in onmouseover, regardless of ...
I'm creating a custom control that contains other controls, including two scroll bars, one horizontal, one vertical. There's a property to set one or both scroll bars invisible, which works fine at runtime, but at design-time it doesn't disappear from the form designer when I set the property. Now, I can understand how this could be a ...
I'm displaying a very big tree with a lot of items in it. Each of these items shows information to the user through its associated UserControl control, and this information has to be updated every 250 milliseconds, which can be a very expensive task since I'm also using reflection to access to some of their values. My first approach was ...
Hey, is it possible to determine whether my UIView is visible to the user or not? My View is added as subview several times into a Tab Bar Controller. Each instance of this view has a NSTimer that updates the view. However I don't want to update a view witch is not visible to the user. Is this possible? Thanks ...
I have code using JPA and everything works fine in my development environment and in unit tests. But deploying my modules into the OSGi target environment, I regularly run into the weirdest class loading issues. I really like OSGi, but if I can't fix this once and for all, I'm going to get stark raving mad. And as long as I don't underst...

I'm working on a multiplayer flash game. The server informs each client what other players are near the player. To do this the server has to check which clients are near each other continuously. The following is what I am using at this moment, as a temporary solution: private function checkVisibilities() { foreach ($this->socketClie...
Does a custom control (ascx) get rendered regardless of whether visibility property is true or false. It seems that when some controls have their visibility set to false, they do not get rendered, yet when I set an ascx control to be hidden from the aspx page that contains it, the code still runs through the ascx's codebind, despite it ...
Hello, i'm implementing a Jlist populated with a lot of elements. Each element corresponds to a image so i'd like to show a resized preview of them inside each row of the list. I've implemented a custom ImageCellRenderer extending the Jlabel and on getListCellRendererComponent i create the thumbnail if there'snt any for that element. Eac...
In the class ReentrantReadWriteLock is the following curious comment: transient ThreadLocalHoldCounter readHolds; Sync() { readHolds = new ThreadLocalHoldCounter(); setState(getState()); // ensures visibility of readHolds } what does it mean by "ensures visibility"? The reason I ask is that I have a situation where it looks a...
Hi, I need to write some code that would loop though all rows of a table, then check a hidden input in each row to see if it contains a certain value and if so, set some values and hide the row. It might be clumsy, but it worked: (variable "zeile" contains the first row, is initialized correctly before the loop): while (goon) { var h...
Hi This Textblock, defined below, shows when the window first loads because it has no Datacontext (and hence the converter code is not run) until an item has been selected from another control e.g. TreeView. <TextBlock Name="tbkDocumentNotFound" Style="{StaticResource StandardText}" Margin="4,4,2,0" TextWrapping="Wrap" ...
I'm having a problem with FIREFOX. I have an invisible list control over a drop-down control (html 'select'). Don't mind why, but I will say that the over-layer is a pop-up that appears as part of another custom control. Even though it's hidden, it's preventing me from clicking on the underlying drop-down control, making the underlyin...
