Large number of distinct values in DistinctFilter

I am programmatically filtering my gridview. The gridview has about 2000 rows, with a column called "Tag" of type uint that has a unique value for each row. In another control, my application user can select or unselect the Tags he wants to see in the gridview.

I'm using DistinctFilter as shown below. I'm seeing very poor performance and even a stackoverflow apparently coming from ResumeNotifications (no stack trace is available for that).
When the user wants to show all 2000 rows, no filtering is needed so that works fine. But when a single row is to be filtered out, I would AddDistinctValue 1999 times.
Is there some better way I should be doing this?

GridViewColumn tagColumn = this.gridView.Columns["Tag"];

IColumnFilterDescriptor tagFilter = tagColumn.ColumnFilterDescriptor;

// Suspend the notifications to avoid multiple data engine updates

tagFilter.SuspendNotifications();

tagFilter.DistinctFilter.Clear();

foreach (var pair in myDictionary)

{

if (pair.Value.IsShown)

{

tagFilter.DistinctFilter.AddDistinctValue(pair.Key);

}

// Resume the notifications to force the data engine to update the filter.

tagFilter.ResumeNotifications();

Export to PDF, what is the correct Mediabox size for A4?

Hi!

When I use this code, to create an empty PDF file (2013Q3SP1):

var filename = "C:\\temp\\test.pdf";

var doc = new Telerik.Windows.Documents.Model.RadDocument();

var stream = new FileStream(filename, FileMode.Create);

var pdfExp = new Telerik.Windows.Documents.FormatProviders.Pdf.PdfFormatProvider();

pdfExp.Export(doc, stream);

stream.Close();

and look at test.pdf I get

/MediaBox [0 0 612 792]

This is OK for letter format, which is the default.

But when I set the size to A4:

doc.SectionDefaultPageSize = Telerik.Windows.Documents.Model.PaperTypeConverter.ToSize(Telerik.Windows.Documents.Model.PaperTypes.A4);

pdfExp.Export(doc, stream);

stream.Close();

the Mediabox looks like this

/MediaBox [0 0 594.75 842.25]

I cannot find an official reference which is the correct size, but when I do a google search with https://www.google.de/search?q="%2FMediaBox+%5B0+0+594.75+842.25%5D" I just get one page of results.But if I use https://www.google.de/search?q=%2FMediaBox+%5B0+0+595+842%5D to search, I get hundreds of pages with this result.

Could you check, which is the correct value and If /MediaBox [0 0 595 842] is the correct one, how to fix it?

Thanks

Caretpositioning / PermissionRangeStart

Dear support,
in our code we have paragraphs consisting of two PermissionRangeStart and a PermissionRangeEnd tags (header and text), each of them encapsulating a span. (see example below).
When the user tries to position the caret at the beginning of the "text" span he is facing a strange behaviour concerning the positioning of the caret at the beginning of the line. When hitting "Pos1" key the caret comes out to be in the previous span (in the header). Pressing the "Arrow right" key does not move the caret (visibly) but then the user can type in the correct span.
When positioning the caret at the beginning of the line via mouse we are having an unpredictable situation whether the user is in the header span or the text span.

How can we solve this?
Thanks in advance!

Jo

Touch support and scrolling

Hi,

I am developing a WPF application for a Windows 7 tablet, and I am wondering if there is a way to allow a RadTileView to be scrolled by using touch / finger gestures?

Thanks!

Loading RadGridView layout fails with System.NullReference Exception in Telerik.Windows.PersistenceFramework.dll

We have been using RadGridView for over a year, quite successfully. We had an old project that implemented the Persistence Framework (using PersistenceManager) and successfully saved/loaded layouts. Now, however, in a new project using the latest DLLs (2013.2.724) the save works fine (supposedly) but the load fails. The error message in the output window is "A first chance exception of type 'System.NullReferenceException' occurred in Telerik.Windows.PersistenceFramework.dll".

We compared streams after saving and after loading and they are identical - so insofar as the save is working correctly, it is persisting the layout to the stream and then loading it back.

We have downloaded samples from these forums and they do indeed work (in the sample) so no one is sure what is going on. The grid we're trying to save is fairly trivial, nothing special. No custom properties, no custom filters. In fact, we copied the Proxies.cs and RadGridViewCustomPropertyProvider.cs from the sample application and it still fails with the same error.

Any assistance would be greatly appreciated. Opened a support ticket on this as well, but have not heard back yet.

IsEnabled

Windows8TouchTheme doesn't show any noticeable change in the control if you disable or enable the control only that the clearcommand x will actually highlight. I tried another theme and well they work. Windows8TouchTheme seems sort of broken with MaskedInputNumeric. This wasn't the case with the previous version of the assembly, presently using 1204.45

ASP.NET GridView Functionality in WPF

Hi, firstly I'm using Telerik products more than 4 years and I've the latest version of products.

As you mentioned in Asp.Net demos, radgrid has edititemtemplate/insertitemtemplate properties. But I cannot make it work in WPF. Is there any way to enhance WPF gridview with ItemTemplates like you do in Asp.Net demos?

ColumnGroupHeaders Issue

Hello!

I have made sample project for you.
Look, ColumnGroupHeader "Price3" doesn't appear, when you resize window, but if you set (in code) window's width to 300, everything works fine.
