Display list content
-
Hello, Is there some control in WPF that i can use to display a list. For example i have a list of objects where each object have some number of properties. I wannt to give this list to the control and he will display each object properties in a row when every propertie displayed in a separate column. So my question is is there some control already in WPF. If not i will have some how to create one but in order to create i have to know how many properties object has,how can i do it? Thanks.

You could use a DataGrid and set
AutoGenerateColumns="True"on it. This assumes that all your properties can be displayed textually - if you have images to display, for instance, you are going to have to take over control yourself. WPF can only go so far.Forgive your enemies - it messes with their heads

Check out ListView, it is customizable to some degree (with AutoGenerateColumns=false) and it will probably serve you just fine.

If you want to auto render then as Pete suggested your best bet is the DataGrid. If however you need more complex displays you can use the ListView and make DataTemplates for the more complicated properties. Then also a data template for the parent property. For example say I have an object
Employeeand with in it I have full name, pay grade, contact info, and picture. I would likely in the parent object have a collection of employees of which the listview has its itemsource bound to.So this defines our Employee collection and how we want Employee to render. However, we have not defined how the properties should be rendered. This is good and bad. By default, if it is a string (e.g. Name) it will display the string. Otherwise it will ToString the object. In this case we want to make DataTemplates for those objects as well. A good example here is the ContactInfo. The contact info may just be Address. Or maybe it includes eMail and even an Instant Messenger contact ID. If these later items are included one could design a control that allows you to IM right from your grid. This is some of the beauty of views not caring about each other. They just know they want to 'show' object 'A'. How object 'A' is rendered is up to some other design/datatemplate.

What is the difference/benefit between this and using ListBox? I thought ListView was supposed to be used with views (ViewBase-derived objects), like GridView - isn't that the case?

There really is not much difference. ListView is a listbox but is defaulted to Extended mode vs Single. I am not sure what you mean by "supposed to be used with views (ViewBase-derived objects), like GridView. Both ListView and ListBox contain collections. How they are rendered is determined by the ItemTemplate, which is editable by the user.

What I meant (and also in my replay to OP) is that ListView (as opposed to ListBox) can be used this way
<ListView>
<ListView.View>
<GridView>
<GridViewColumn DisplayMemberBinding="{Binding FirstName}" Header="First Name" />
...
</GridView>
<ListView.View>
</ListView>where the individual columns can be either autogenerated or more or less customized. Which I assume is what the OP wanted. This displays the "grid-view" known for example from file explorer if you select display mode->details. This is (I think) the primary purpose of ListView.

There is a huge difference between ListView and ListBox. ListBox just displays a flat list of items whereas ListView supports columns, grouping, etc.

Seems like you are just nit picking now. The differences are subtle at best. ListView inherits from ListBox. ListView just exposes View as was pointed out. To say their is a 'huge' difference is odd since they essentially are the same except for this feature. Granted a nice feature, but hardly a 'huge' difference. http://msdn.microsoft.com/en-us/library/system.windows.controls.listview.aspx[^]
