Hello,

My problem is: the grid view contains cells with more than the total number of characters that an excel cell can contain (32,767 characters) and I export the data to excel with ToExcelML and I got the error at opening the result file. Is there a solution to limit just the export, without limit the grid cell?

Thank you.

[Solved] How to find selected cells after scroll?

Hi,
I have a radgridview where the user can make a random cells multiselection (see the attachment).
On the click button I need to know which cells are been selected. More specifically, for each row I need to know the item and the column of the selected cells.
If I use the radgridview.SelectedCells everything is works since the cells are visible, when I scroll the rows in the radgridview.SelectedCells they disappear.

How can I do?
Thanks

pivotgrid radchart integration

I have put together a pivotgrid control that I want to use, that works fine. I now want to integrate the radchart view as per the wpf demo and all I get are errors simalr to

Error 2 The resource "BarSeriesStyle" could not be resolved.

I have then downloaded the Telerik WPF demo source code and get the same error. I preumse I am missing something on my PC, but need to get this working so I can replace some legacy software.

[Solved] Syncing RadGridView and RadDataform with QueryableCollectionView

I want to syncronize my RadGridView with my RadDataForm. Defining a CollectionViewSource in the XAML of the view bound to an ObservableCollection in the ViewModel does not work 100% because this will fail when we set a filter on the RadGridView. So after taking a look at your demos and manuals it seems that I have to use your QueryableCollectionView class to achieve correct syncronization.

In your demo you use QueryableCollectionView inside your ViewModel but the class needs Telerik.Windows.Data and WindowsBase.dll. Both of this DLLs are imho attached to "view stuff" and should not be in the ViewModel. In my case my ViewModel project is a portable class library which makes it impossible to import any of those view related libraries.

So here's the question? Can I use QueryableCollectionView in XAML like CollectionViewSource? If not how else can I get 100% working syncronization?

Help with Documentation and "Image"

In the documentation over at (http://www.telerik.com/help/wpf/carousel-getting-started.html) we find the following snippet at the bottom when discussing how to add images to the carousel. I'm sure this looks fine to you but where/what is "Image"?

List<Image> myImages = new List<Image>();

Image myImage = new Image();

myImage.Source = new BitmapImage(new Uri("/Images/nature1.jpg", UriKind.Relative));

myImage.Height = 200;

myImage.Width = 200;

myImages.Add(myImage);

The only image I can find is System.Drawing.Image and that ain't it. All that displays is a text block detailing the image's properties. At least is displays something.

I have found vague references to this being a "UI Element" whatever that is. I've been all over these forums, stackoverflow and the web in general, what am I missing here?

Hot to implemente a Custom Geocode Provider?

We are converting our WPF application from a third-party tool and control to a custom in-house Open Street Maps based solution and the RadMap control. The WPF application used to use the third-party's geocoding solution to convert locations into street addresses and nearest cross street.

According to the documentation, the only GeocodeProvider built into UI for WPF is the BingGeocodeProvider. Do you have any sample code that will show me how to implement my own custom GeocodeProvider?

Is there a way within Wpf to disable collapsing of a Column Group Description?
I have a Type, SubType and then Aggregations.
Currently the user can collapse the Type on the Column Group.
I want to prevent them from collapsing all the types and leave the last one open.
