Is the engine being used to evaluate text expressions built into the RadExpressionEditor, or is it a separate assembly? I would like to use the RadExpressionEditor to build expressions within a WPF environment, but then I need to be able to take that expression text and rebuild the expression in an environment that does not have references to the WPF related assemblies.

Thanks,
Brian

[Solved] Getting invalid and valid rows (IDataErrorInfo)

Hi,

I am using RadGridView to display a List of objects that implement IDataErrorInfo, this list is being populated by objects imported from an XML file. Unfortunately some of the records may contain invalid data which the application should point out. Implementing IDataErrorInfo lets me do this wonderfully.

However, I would like to find a way to get these invalid rows, and valid ones, and I have not managed to find a way to do so.

Any ideas?

Thanks,
Daryl

RadDataForm Add Button Problem

Dear support,

When I click "Add", fill-in data and then "OK", the data has successfully put in the collection but "Add" button is still disabled.
I have to click "Edit" follow by "Cancel" so that the "Add" button become enabled again.

Now I know what cause the problem.
The dataform was bound to a ListCollectionView of objects that implement IEditableObject and INotifyPropertyChanged.
By design, those objects raised OnPropertyChanged event on EndEdit or CancelEdit method because there were some changes in their internal properties. This made the dataform think the object has been changed again so it didn't enable navigation and Add New buttons.

My question, can we make the dataform pay attention to only those properties bound to UI element under the dataform, or is there any other solution?

thanks,
Meaw

Any built-in support for Navigation Properties from OData sources?

I notice that out-of-the-box the RadGridView auto-generates columns for navigation properties from an OData source, regardless of whether or not they were actually expanded by the query. Is there anything built into the controls to more flexibly handle navigation properties? I was thinking it might be nice to automatically generate hyperlinks in these cells that would issue the appropriate query back to the service when clicked.

It looks like I could roll my own scheme by intercepting AutoGeneratingColumn and setting up a cell template, but then how would I determine the link information from the feed?

[Solved] Multiple Select GridViewComboBoxColumn

I'm looking for a quick way to implement a multi-select GridViewComboBoxColumn that will bind to a nested string list collection. The most current discussion I could find was this post (http://www.telerik.com/community/forums/silverlight/gridview/multi-select-combobox-column-in-grid-view.aspx) which is 2 years old. Has this feature been implemented since then?

Determine Source of Close

Now that there is a CloseButtonPostion property which can be set to InPaneAndGroup, is there any way to determine the source of the PreviewClose event; either from a pane or from the group? If not it would be useful.

Thanks in advance,
Steve
