I'm binding a RadGridView to a collection of objects that implement INotifyPropertyChanged. Sometimes the properties on those objects are changed by a thread that isn't the gui thread. This causes a "calling thread cannot access this object" error.

I understand that normally non gui threads can't access gui objects, but in this case it should work, in every other WPF control I use it works fine, presumably because behind the scenes they use Dispatcher.Invoke(...) on all propertychanged notifications.

thanks

Hello,

I am using this control and am having negative feedback because users cannot type in .6 for example and get the control to display 0.6.
Instead if you type .6 the control actually displays 6.0. Is there anything that can be done about this??

Thanks.

Hello
I am trying to save the RadPivotGrid after user has defined the pivot through the RadPivotFieldList, so when i will load it 
it will load with all of the definition. I understand that most of it is stored in the LocalDataSourceProvider.
is there way to save and restore the LocalDataSourceProvider to a file?

Imagine a carousel, and on each carousel pane there is something that looks like a vertically oriented business card or a property grid, with interactive data-entry fields. Some of the data fields are textboxes, some are radio button groups, and some are datepickers, some are simple dropdown lists, and one is a "popout" notes field. Is something like this possible in WPF?  Would there be a way to search rapidly through the dataset (it could contain as many as  10,000 items) and when  a match is found, the carousel would "zoom" that record into the focused pane of the carousel?

I'm having issues with multi-selection of my treeview and I'm wondering what I'm doing wrong. I'm trying to get multi-select to work the way I expect on the RadTreeView, however I've found that every time I hold the ctrl key and shift key simultaneously, it seems to ignore the shift key and acts only in the normal ctrl key selection mode (where it selects only the item being clicked, rather than being able to click on an item with the ctrl key, then a second item with ctrl shift and select the new block, leaving any existing selection alone). Normal shift-select works as expected, and normal ctrl-select works just fine too, but ctrl-shift select just seems to work no differently than plain ctrl select, so like its ignoring the shfit key in that circumstance.

If you've read my post history, you may have read that I was trying to override default treeview selection behavior previously, but thankfully the project specification changed to just do the default windows treeview selection style, so I removed all previous overrides of event handlers I had in place and I'm just trying to use extended selection mode.

My xaml:


Any clues as to what I may be doing wrong?

Thanks!

I am using a RadGridView with a bound QueryableCollectionView.

Virtualization is enabled

Anytime I scroll through the grid, memory usage of the application goes up and up and up, and never comes back down, even after forcing calls to GC.Collect().  Am I missing something here or is there some issue with scrolling through a QueryableCollectionView?

Thanks,

Hi,

I would like to add conditional formatting to cells in the summary footer row (I want the display values from GridViewColumn.AggregateFunctions to have different background colors based on if they are negative or positive, plus other conditions).

I see that there is a property for GridViewColumn.GroupFooterCellStyleSelector, but what I think I need is one for a property that does not exist in the API:  GridViewColumn.FooterCellStyleSelector...

How should I proceed?

Kind Regards,
Albert

I am struggling with how I go about this?  In my VM I have a nullable bool property that I want to bind to a Yes/No(true/false) RadRadioButton.  Can someone point me in the right direction?
