Hello,

In certain cases I need to allow user to edit and delete rows, but in certain cases user can edit rows, but can not delete them

How can I disable deletion of rows?

Thank You

We are building a custom AutoCompleteBox using the RadGridView control internally. We are binding the ItemsSource against a IQueryable(Of T) from NHibernate and using the CustomFilterDescriptor from this article.

When using only one filter member it works:

But when using more than one, like this:

Throws an ArgumentException: An item with the same key has already been added.

We are using the latest Q3 beta assemblies.

I am using  RadGridView to display some data.

When data in one column changes, I want to change the data in another column based on a simple formula.
For example: When data in Age column is edited, I want to change the other column's (Premium) value as Premium = (Age * 1.2)

Handling CellEditEnded or RowEditEnded doesn't help at all. Any ideas?

Hi

Is it possible to implement editable hierarchial grid using this control. I was not sure as there are no samples online. I have to implement an hierachial gridview with checkboxes which i succeeded in implementing but wanted to see if this control can be used to achieve the same purpose. Please see the image for the effect i am looking for.

Regards
Kiran

I sort of need a fairly quick answer....please?

Hi, I'm trying to use the code snippet found here to persist my grid current filter but it fail to serialize at all.

I get an InvalidDataContractException on type FilterDescriptorUnsetValue cannot be serialized.  I'm using a trial I downloaded 2 weeks ago for evaluation.

Is this a bug or am I missing something to make this work?  Also, any plan on supporting this feature built in the library at some point in the future?  We don't really want to maintaining it ourselves you see.

Thanks

Is there a way to have the Toolbar take up the full width of the container control?  

HorizontalAlignment="Stretch"
Width="Auto"

Doesn't seem to have any effect.

We are getting following error: Is there any solution for this to fix
