Datagrid In Windows Form Application

Resources The complete WPF tutorial. WPF introduces a very handy concept The ability to store data as a resource, either locally for a control, locally for the entire window or globally for. The data can be pretty much whatever you want, from actual information to a hierarchy of WPF controls. This allows you to place. The concept is used a lot for styles and templates, which well discuss later on in this tutorial, but as it will be illustrated in this chapter, you can. Allow me to demonstrate it with a simple example. Window x ClassWpf. Tutorial. Samples. WPFApplication. Resource. Sample. xmlnshttp schemas. System assemblymscorlib. TitleResource. Sample Height1.

The core thing here is to know that the. I was recently working on a requirement to perform Update and Delete operations on a WPF DataGrid control similar to what developers do in a ASP. NET Grid control. Note 2008 and older issues are only available as. On most versions of windows you must first save these files to your local machine, and then unblock the.

Resources are given a key, using the x Key attribute, which allows you to reference it from other parts of the application by using this key, in. Static. Resource markup extension. In this example, I just store a simple string, which I then use from two different Text. Block controls. Static. Resource vs. Dynamic. Resource. In the examples so far, I have used the Static. Resource markup extension to reference a resource. However, an alternative exists, in form of the. Dynamic. Resource. The main difference is that a static resource is resolved only once, which is at the point where the XAML is loaded. If the resource is then changed later. The WPF DataGrid is a very flexible tool, however in its current state certain simple tasks can prove to be rather tricky. A fairly common task when working with. Static. Resource. A Dynamic. Resource on the other hand, is resolved once its actually needed, and then again if the resource changes. Think of it as binding to a static. Dynamic resources also allows you to use resources which are not even there during design time, e. Code behind during the startup of the application. More resource types. Sharing a simple string was easy, but you can do much more. In the next example, Ill also store a complete array of strings, along with a gradient brush. This should give you a pretty good idea of just how much you can do with resources. Window x ClassWpf. Tutorial. Samples. WPFApplication. Extended. Resource. Sample. System assemblymscorlib.

This time, weve added a couple of extra resources, so that our Window now contains a simple string, an array of strings and a Linear. Gradient. Brush. The. Combo. Box control and the gradient brush is used as background for the entire. So, as you can see, pretty much anything can be stored as a resource. Local and application wide resources. For now, we have stored resources on a window level, which means that you can access them from all over the window. If you only need a given resource for a specific control, you can make it more local by adding it to this specific control, instead of the window. It works. exactly the same way, the only difference being that you can now only access from inside the scope of the control where you put it. Stack. Panel Margin1. Stack. Panel. Resources. String x KeyCombo. Box. Title Items lt sys String. Stack. Panel. Resources. Label ContentStatic. Resource Combo. Box. Title. lt Stack. Panel. In this case, we add the resource to the Stack. Panel and then use it from its child control, the Label. Other controls inside of the Stack. Panel could have. Controls outside of this particular Stack. Panel wouldnt have. If you need the ability to access the resource from several windows, this is possible as well. The App. xaml file can contain resources. WPF control, and when you store them in App. It works exactly the same way as when storing and using from a Window. Application x ClassWpf. Tutorial. Samples. App. xmlnshttp schemas.

So far, weve accessed all of our resources directly from XAML, using a markup extension. However, you can of course access your resources from Code behind. In the previous example, we saw how we could store resources in several different places, so in this. Code behind, each stored in a different scope. Application x ClassWpf. Tutorial. Samples.

So, as you can see, we store three different Hello, world messages One in App. The. interface consists of a button and a List. Box. In Code behind, we handle the click event of the button, in which we add each of the text strings to the List. Box, as seen on the screenshot. We use the Find. Resource method, which will return the resource as an object if found, and then we turn it into the string that we know it is by. To. String method. Notice how we use the Find. Resource method on different scopes first on the panel, then on the window and then on the current Application object. It makes sense to look for the resource where we know it is, but as already mentioned, if a resource is not found, the. Find. Resource method on the panel in all three cases, since it would have. The same is not true the other way around the search doesnt navigate down the tree, so you cant start looking for a resource on the application level.
