Virtual Paging and Scrolling for GridView

The ASP.NET controls library has the ability to load items on-demand as the vertial scroll bar in a Grid is moved up or down. Does the WPF GridView have a similar capability or am I limited to the standard paging layouts used, i.e. RadDataPager?

XML Data and Two Way Binding

Hello all,
I am trying to create a configuration window that binds to an external XML file and implements two way binding in XAML. I have basically used the RadGridView demo as a starting point and have started to modify my code to implement the the two way binding piece, however I have hit a road block.

First off I am wondering whether I should use a DependencyObject or implement INotifiedProperty. At this point I am using a DependencyObject, however my textboxes do not appear to bind to the data, but the RadGridView does.

Basically I want to use the RadGridView as a list box on steroids and use the textboxes to edit/add records. However since this is an external xml file I am bit confused on what direction to take. Also I am using a ObservableCollection as my datasource, just as you do in the RadGridView demo, but I have also played around with using a XMLDataProvider. Any suggestions here?

Below are the basic classes I have so far.

Thanks for your help!

Cell Template Selector ?

Hello,

I have table with a XML-Column (XElement). I would like to format the cell according to the specified XML-Data, so I was looking for a GridViewDataColumn.CellTemplateSelector but I did not found one.

Do you have an easy way to get this behaviour?

I have several DataTemplates for the XMLs which I want to use.

I was trying to style the GridViewCell and set the ContentControl.ContentTemplateSelector but this was not recognized by the RadGridView.

Do I have any other oportunities ?

Group Expand/Collapse Event

Hello,

I am using the GridView in my application. If I group the rows with a specific column, all the rows are grouped by that column and displayed accordingly. I want to get the group name on expand/collapse of a particular group. I am able to achieve this on expand by using the rowloaded event. But when I collapse the same group it is not firing. Can you tell me how can I achieve this.

Thanks

Row-Style depending on Content?

I have following problem: i have a grid with several rows. Several user can edit the content at the same time. To avoid problems with saving data, rows which are currently editing have to be locked.
What i have until now, is a column with the username who is editing the row. If there is no editing, the cell has no value.
What I want: the style of currently editing rows should differ from the other rows e.g. font-style should be italic und light-gray. And the user should not have the possibility to select this row. Please help!
Thx
