Hi,

Please bear with me as I am a newbie to WPF and we are evaluating RadGridView as part of a new development project. I

a question on how to use conditional values within a row on the grid.

I have a grid which is bound to a simple data table, contacts. Now contacts has several different columns that represent different phone numbers. I also have a column that has a "default contact mode" that does what it basically says it is used to identify which phone number should be used as a default contact number.

How do I define a column that shows the default contact number, that is I do not want to show say all the different phone number columns, just the column that is defined in the "default contact mode". Bearing in mind that this default contact mode will be different for different records.

For example I have a data set that looks like:

Name    Phone1    Phone2    Contact Using
Joe        123412    432112    Phone1
Jane      999999    777777    Phone2
Jack       666666    333333    Phone1

So the Grid would look something like

Name    Contact No
Joe        123412
Jane      777777
Jack       666666

Hope that make sense :)

Any help would be greatly appreciated.

Specifying a Converter Parameter

Hi guys,
Is there a way to specify a converter parameter in this control? I have tried to specify a ConverterParameter in the binding to the value property, but in the ConvertBack method of the converter, the ConverterParameter is always null. Maybe this is due to something happening internally in the control. There is also a ValueToTextConverter property, but you cannot specify a ConverterParameter either. Basically I want to use one converter that would apply to a variety of masks. Any help would be appreciated.

Thank you,

I can modify things like e.DataField.Label or e.DataField.Height but i wold like to know how to acces the editor fields (more specific, i want to modify let's say, the height, width or background color of the control).

Also in this event can i modify the type of the control that is being generate for a specific property?
Something like: if (e.PropertyName == "Name") choose a type for the generated control.

Thank you.

Sync between RadTreeView and RadCarousel

I am using both a RadTreeView and a RadCarousel and bind the root nodes of the tree view and the carousel to the same list of items. If the user change the selection on one control, I would like the app to automaticall change the selected item on the other control. I tried to bind the SelectedItem property on both control to the same object but that did work. Has anyone tried this before? Thanks.

A problem with WPF RadGridView under WinForms

Hello!

I have a big Windows.Forms project, but we also use WPF controls.
I have two ElementHosts, and in each I have one RadGridView.

All was good, but now we need grouping, and have a problem with it.
Grouping works only for one of the grids. And more, it isn't works after close and open window again.

I cannot attach here my example, but can send it via e-mail, if you need it.

Roman.

Multiple Series

I am doing a review of 7 major chart controls for WPF and during my review of the RadControl for WPF I cannot find a way to bind two separate Line Series on a single chart to individual properties of an underlying view model.

My view model has two ObservableCollection properties. FixedPoints is populated in the constructor to represent a collection of static data points that are known at startup. DynamicPoints is populated via Rx's Observable.Interval to simulate a real time steam of data being plotted.

I want a single chart control to display two line series each plotting one of the collections mentioned, but it seems the only place I can bind to my view model is on the RadChart so I have a single ItemsSource to bind. Is this correct? I need to do this completely declaritively no code behind work arounds.

I found a sample that uses a collection of collections and sets the CollectionIndex of each SeriesMapping but that is completely against the MVVM pattern. It means I have to design any view model according the choice of chart control. It is also IMHO a very ugly implementation.
