Hello all, In a WPF UserControl, I have to make to call to a WebService. I am making this call on a separate thread but I want to inform the user that the call may take some time.

WPF validation system performs intial validatation of an object (I mean - all fields are validated when a databound item is changed, and results are displayed on the ui). But it doesn't work like this, when I add a control dynamically. In such case inital validation happens, but results aren't shown on the ui. Only after some properties ...

Hi, I am building a control, where the user can "draw" resizable rectangles that are laid over the content. To resize those rectangles, I use an Adorner on top of them which contains 4 Thumbs to change the size of the rectangle. The problem is, that this control is is "zoomable", meaning a ScaleTransform is applied to the whole control...
Hi, I have an ItemsControl in a ScrollViewer. The items in the ItemsControl are expanded to a DataTemplate which basically consists of an Adorner. Now the problem is, when scrolling, the Visual Children of the Adorner are visible outside the ScrollViewer. Lets say I scroll from the Horizontal Offset 0 to 100, the Visual Children of the...
I made the example below which enables a factory to pack objects with functionality, but the problem is that the functionality is divorced from the object. My ultimate goal is attach functionality such as log, and save and display which operates on the specific properties that each different object has. How would I keep the exterior a...

Hello, I'm creating a Loading Adorner that has a swirling icon over it. I tried binding the visibility property directly in the XAML but that actually hides everything inside its hierarchy.

I'm trying to decorate an ItemsControl so that each item will have a Delete button that floats over the item's content under a specific condition inspired by somewhat by the iPhone UI. I have a few ways in mind of how I can approach this but I could use some guidance from other WPF folks who might have a better idea about how this would ...
Hello, I have a canvas (Panel Control) in my WinForms app where users can drag things like textbox's, labels etc around. But I want to make it easier for them to more precisely align the objects. I've read into it and Adorners seem to be the way to go? But, apparently it's only for WPF. WPF is not an option for me, unfortunately. What ...
I'm using the System.Windows.Controls.WebBrowser for various things in my app and I've noticed that adorners are cut off when they are supposed to appear over a WebBrowser. I realize that the WebBrowser control is really a wrapper around a COM component and probably renders differently, but I wondered if anyone figured out how to solve ...

When a user clicks a button, I run an animation to transform the ContentPresenter's Height and Width properties to 896,1024 (actually it does 3 rotations whilst its growing, too) and this is all good... The DataContext for the User c...

In a UI I'm building, I want to adorn a panel whenever one of the controls in the panel has the focus. So I handle the IsKeyboardFocusWithinChanged event, and add an adorner to the element when it gains the focus and remove the adorner when it loses focus. This seems to work OK. The problem I'm having is that the adorner isn't getting...
