Hey there,

I'm currently searching for a way to set the radRichTextBox size to CM or inches.
Something like in the
radRichTextBoxRibbonUi -- Page layout -- Size
but not with predesigned sizes.

Is there a given way to do that or do I have to calculate the size via ppi?

Thanks for any help! :)

Cannot add to ItemMappingCollection after updating updateing to newest

Hi.
I updated to the newest version of Telerik Dll's and I cannot add to ItemMappingCollection (Witch I could without problem)

code:

private void createSeriesMappings(int count, string value, string stackName)

{

for (int i = 0; i < count; i++)

{

SeriesMapping seriesMapping                                         = new SeriesMapping();

seriesMapping.SeriesDefinition                                      = new StackedBarSeriesDefinition(stackName);

seriesMapping.SeriesDefinition.ShowItemToolTips = true;

seriesMapping.SeriesDefinition.ShowItemLabels = false;

seriesMapping.SeriesDefinition.InteractivitySettings.HoverScope = InteractivityScope.Series;

seriesMapping.SeriesDefinition.InteractivitySettings.SelectionScope = InteractivityScope.Series;

seriesMapping.ItemMappings.Add(new ItemMapping("[" + i + "]." + value, DataPointMember.YValue)); // this gives me the error

chart.SeriesMappings.Add(seriesMapping);

}

}



the error

'Telerik.Windows.Controls.Charting.ItemMappingCollection' does not contain a definition for 'Add' and no extension method 'Add' accepting a first argument of type 'Telerik.Windows.Controls.Charting.ItemMappingCollection' could be found (are you missing a using directive or an assembly reference?) 



How can I solve this ?



Best regards

PersistenceManager.LoadFromXml vs Assembly Versions

Hi All,

We use Telerik's PersistenceManager capabilities to save user settings to XML in a relational database (as desribed here).
In particular, some of RadGridView's settings are stored this way.
This has worked fine for several months, until we performed an update of our Telerik libraries last week.

The XML the PersistenceManager produces, contains some type information concerning the types that were serialized to XML,
and contains lines like this:

<TI K="-134624143" N=

"Telerik.Windows.Controls.GridView.GridViewLengthConverter, Telerik.Windows.Controls.GridView, Version=2011.2.712.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7"

/>

After the Telerik libraries update, this causes an exception because we now use Telerik.Windows.Controls.GridView v2012...
When PersistenceManager.LoadFromXml is called, the PersistenceFramework tries to load the Type,
resulting in a TypeLoadException:

Could not load file or assembly 'Telerik.Windows.Controls.GridView,

Version=2011.2.712.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one

of its dependencies. The located assembly's manifest definition does not match

the assembly reference. (Exception from HRESULT: 0x80131040)

What is the best option to avoid this on Telerik updates?
Can we tell the Serializer not to Save the fully qualified type name to XML?

Thanks for your time,
Koen

Styling ChildTable in Hierarchical Grid

Is there a way to provide a different style for the grid generated in a hierarchy. E.g. Can the parent grid use one style, while the child grid uses another?

Cheers

RadGridView removes ColumnSortDescriptor

The RadGridView removes the ColumnSortDescriptor when there is no data to display. The result is that when there is data again, it isn't sorted any more.

My specific case is as follows: I have two grids. The second grid shows the items from a List<> property of the selected item in the first grid. When the second grid is sorted (either because I added a ColumnSortDescriptor in the constructor or because the column was clicked in the GUI) and in the first grid a row is selected that doesn't have any items in the List, then the second grid shows no items (correctly) and the sorting arrow disappears. After a row is selected that does have items in the List, the second grid shows these items, but the sorting is gone.

Is there a way to make this sorting more persistent?

Thanks in advance,
Herre

Sum function does not work if type implements ICustomTypeDescriptor

Aggregation functions (Sum, Min, Max) do not work if type implements ICustomTypeDescriptor.
Same scenario with RadGridView works fine.
ICustomTypeDescriptor implementation.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Linq;

insertHyperlinkCallback

problem In short description:

I have my HTML string, with href(s) inside, for example:
<a href="cfb32e1b-1f4c-4ba0-b278-0ea89a1ea4e3" target="_blank"><span class="s_7EDD076B" dir="RTL">ארינה</span></a>

i do this flow:
var provider = new HtmlFormatProvider();
textCtrl.Document = provider.Import(text);

After i do it my HTML is changed by Telerik controls by removing dir="RTL" from my href(s).
So in UI these href(s) are displayed LTR, for example:
<a href="cfb32e1b-1f4c-4ba0-b278-0ea89a1ea4e3" target="_blank"><span class="s_7EDD076B">ארינה</span></a>

RadRibbonView Backstage - WebBrowser

Hi Telerik Team!

I’m evaluating your WPF control bundle for one of our new applications and have some problems regarding the backstage tab in combination with a WebBrowser control in the content area of my prototype. Although the backstage tab is active, the WebBrowser control is visible and overlaps my backstage-content. Is there a way how I can solve this problem?

Best regards,

Dominik
