Wpf selecteditem not updating
Abstract: I was recently working on a requirement to perform Update and Delete operations on a WPF Data Grid control (similar to what developers do in a ASP. The WPF Data Grid is an excellent control to bind with collections and provides various events to work with. Now since Salary and Dept No can be updated, on the click event of the ‘Update’ button, the following code is written.
Instead, you create classes that represent the database and its tables, and use those classes to interact with data.(Yes, I could have published an XBAP sample, but I was not willing to give up the glow effect used for the selected character…which is, incidentally, achieved using a Drop Shadow Effect in the new effects pipeline.) Even in the new pipeline, Drop Shadow Effect is a rather expensive effect because it requires multiple passes.Since then, I have periodically been asked how one would go about creating a panel that behaves like the application launcher in Surface.If you have not seen the app launcher, I would describe the panel as simply a horizontal Stack Panel that infinitely cycles its children.Okay, this post isn’t really about creating a full blown Natural User Interface (NUI)…
I just wanted to jump on the NUI bandwagon while it’s still the cool new thing!
The class supports dragging its items in a manner similar to the Surface app launcher.
This demo brings the same type of natural user interaction to desktop WPF (via mouse) that you might find on Surface.
The Loop Panel Layout Algorithm Whenever I’m creating a new panel, I start by clearly defining its layout algorithm.
This allows me to identify the exact properties that will be necessary to support the new layout.
If you are actually developing for Surface, be sure to check out the , I would highly recommend it as a foundation for this article.
