This blog post will walk through a simple example, showing you how to create a user control, add dependency properties, wire them to the user control XAML and make a truly re-useable control.We'll start with a very simple example, an application that displays a simple form field which consists of a name and a value: This produces the expected behaviour, a label and a text field that allows you to edit the Shoesize property: Let's say we want to allow the user to edit the Height property as well.
While registering we need to provide the Control name along with the data item for the control which we want to render. we can call args.get_data Items()to retreive the data from the dataitem collections.
If we click on Button1 now, it will update the text of Label1, but though we have registered the Label2 with the script manager still its value will not be reflect. After that we have set the Control Value by from the data item collection using .
Is it possible to have pages with more than one update panel, and allowing these panels to talk to each other? Imagine this example: You have a page that mimmicks a Windows Explorer.
At the left side you have a tree structure, and the right side is a list of icons.
This blog post provides step-by-step instructions for creating a user control, which exposes bindable properties, in WPF and Silverlight.
The post covers dependency properties, and how to manage Data Context inheritance.When opening and closing the treelist you would not have the icon list to update.When clicking a node on the treelist, the icon list should update.The WPF and Silverlight frameworks provide custom controls and user controls as a mechanism for re-using blocks of UI elements.Custom controls are rather special, with the logic being de-coupled from the XAML in order to support templating.The thumbnail list then contains a public function called “Bind Data Source” or “Update List” that takes some parameters of which items to show.
