Intellisense for WPF application

Question

Hi I've been searching for a control that gives me the ability to add intellisense to my textbox. If the user is typing pat. I would like to create an intellisense out of an existing collection to select the name of that object. So I' m not searching for an autocomplete texbox but something like in the editor of visual studio when i'm writing text in a C sharp file. Does anyone know a control that can do that? Greetings

This isn't exactly a challenge but probably a large ammount of coding. I plan on implementing Intellisense features into a custom syntax highlighting box that im working on. I advise if you plan on having it change from time to time keep a few arrays of the strings that will be displayed in the auto complete. And have a listbox on your screen that you search through based on the text being type. You can use the on textchanged event and hold a string that you can reset when the control is clicked or a space or enter button is pressed. and when you use backspace i advise you trim the string by 1. Be sure to update the search through your list box with each text changed event though.

Hey I'm actually not using classes but instances. so i have a collection of Patterns in the database to a Pattern Object List so when i type pat. i want that collection to pop up in some way of intellisense Btw I would be able to use the reflection part also for a Dynamic BusinessRule part in my application. (The clients of the company are able to add businesslogic themselves right before the save of an object to the database.) to get the list of properties fields methods there's no problem at all but i was hoping that there is some intellisence object available which you can use in some way. greets

You need reflection to read all members of an object unless you have them hardcoded somewhere. Say you have 100 classes how would you know what method or property a class have? Reflection will help you read the class properties and methods that you will load dynamically. This is how Intellisense works in Visual Studio.

why do i need reflection? i already know the type i'm going to call :) it's just as simple as showing the listbox after typing pat. and from that moment on filter the list with the word after it.

You need to use Reflection to read that object and its members and then show them as a drop down. I do not know any built-in control something like this.

thanks for your quick reply. Actually i'm not in need of a textbox that will autocomplete but let's say when I type in a textbox like in visual studio and i type the name of an object (in this case my object is pat short for patterns) that i will get all the patterns in a list. Greetings
