Hi

I need to extract text from a ranges of DocumentElements.
For example the text between a BookmarkRangeStart and its paired BookmarkRangeEnd.

My solution is to walk from NextSibling to NextSibling, check the siblings to be of type Span
and get the text. If they are not Spans I recursively walk through the Children collection
and of the sibling, check these to be spans, if not recurse again etc or quit if there are no Children
unti I reach the BookmarkRangeEnd as the last Sibling.
This seems to work.
Questions:
1) is there an easier / more reliable way to get the text of "range" of elements?
(I use TextFormatter.Export for complete Documents, but not for parts)
2) is text always located inside Spans?
3) Can Spans be nested - If so, does the Text property of the "parent" Span contain
the Text content of all "child" spans? (Like InnerText in HTML)?
4) Is there a straight forward way to get the text from a Table as a CSV / TSV string?

Grettings,
Chris

RadWindow lags while dragging

Hi

we have a problem with the RadWindow while dragging it with the mouse.
It only happens when you have "show window content while dragging" enabled in the windows-system preferences.

I think I don't have to attach an example, because it also happens in the "WPF Controls Examples".
The problem only occurs when the RadWindow is very large. So if you resize the RadWindow from the "Frist Look" example to cover nearly the entire size of the monitor and try to drag it around with the mouse, it lags behind the mouse enormously.

If you have a high resolution (e.g. 1920 x 1080), a big RadWindow (which covers nearly the entire screen) lags more then a big RadWindow on 1024x768 while dragging.

Is there a way to fix this?

Simple gauge with 2011 Q2

Hi everyone,

I’m using the 2011 Q2 WPF package.

Is it possible to remove the background to create a very simple style.
Like the styles from the new Telerik gauges?

Thanks!

greetings,

Christian

MinorTickLength sets the AppointmentMinLength?

Hi,

I add appointments programmaticaly to the appointmentslist and calculate the end new. If i calculate an end which is smaler than 1 hour (MinorTickLength = 1h) the ScheduleView shows me anyhow the appointment with 1h lenght. My tooltip shows me the real start and end but the scheduleview appointment-bar not. I set the BeginEdit and Commit things and i remove and add the appointments again to the property, but always he shows me the appointment-bar wrong.

Look at my picture. In this example i have 2 Appointments but it looks like 3 Appointments. What is the little shadow over the green appointment? These "shadow" has the rigth length.

I want that an appointment end is 12:59 pm or the start of the next appointment diff 1 minute. No overlapping!

Here my code:
this is the calculating in method

private void RefeshAppointmentSettings()

{

// ... do some stuff

CustomAppointment previous = null;

var i = 0;

foreach (var custSorted in toSort)

{

if (i > 0)

{

if (previous != null)

{

previous.End = custSorted.Start.AddMinutes(-1);

}

previous = custSorted;

previous.End = previous.Start.Date.AddDays(1).AddMinutes(-1);

i++;

}

Appointments.AddRange(toSort);

// ... do some stuff

}

this is the caller event:

private void SwitchTimeSpecialTimeTLostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)

{

var scheduleViewModel = DataContext as ScheduleViewModel;

if (scheduleViewModel != null)

{

scheduleViewModel.RefeshAppointmentSettings();

_radSchedView.BeginEdit();

var arr = new CustomAppointment[scheduleViewModel.Appointments.Count];

scheduleViewModel.Appointments.CopyTo(arr, 0);

scheduleViewModel.Appointments.Clear();

for(int i = 0;i<arr.Length;i++)

{

scheduleViewModel.Appointments.Add(arr[i]);

}

_radSchedView.Commit();

}

Thanks

Intellisense for MajorTickLength / MinorTickLength crashes VS 2010

Hi,

I wonder if someone have the same problem like me. I have set the Minor and MajorTickLength of scheduleview in xaml. And every time if i type the = and VS 2010 wants to open the intellisense for these properties the VS 2010 crashes. To use these properties in xaml i must type the code including the values in an editor like Notepad and copy/paste it to the xaml-file.

Is this a bug of VS or of the control? Any other intellisense works.

Thanks

SerializationTag not restored after load

Hello,
I use the two methods provided in the sample for saving a raddocking

private string SaveLayoutAsString(RadDocking instance)

{

MemoryStream stream = new MemoryStream();

instance.SaveLayout(stream,true);

stream.Seek(0, SeekOrigin.Begin);

StreamReader reader = new StreamReader(stream);

return reader.ReadToEnd();

}

private void LoadLayoutFromString(string xml, RadDocking instance)

{

using (Stream stream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))

{

stream.Seek(0, SeekOrigin.Begin);

instance.LoadLayout(stream,true);

}

When I restore to the saved status I've the SerializationTag to null (I've also tried to set the tag field but it's the same, it's not serialized)
Any suggestion, reason it's happening?

Thanks

Need Custom Sorting on Groups in RadGridView

Hi,

I have a RadGridView grouped on a property of the binding object.

GroupDescriptor phaseDescriptor = new GroupDescriptor();

phaseDescriptor.Member = "PhaseName";

this.grdScope.GroupDescriptors.Insert(0, phaseDescriptor);

The collection of object bound to grid is "Task" with a property "PhaseName"

The Task object contains another property of type "Phase" whose Name property is same as Task's PhaseName property.

The type Phase defines another property "Index". I want to sort the Groups according to this index. Right now I can only sort the groups ascending or descending based on PhaseName only.

Any ideas?

RadRibbonWindow won't resize if Backstage is open

Hi,

When we use a RibbonWindow with Backstage, and open the backstage view, we can't change the size of the window using the mouse. Only minimizing and maximizing works. If we close backstage the window is sizable again. This is reproducible on the RibbonWindow sample of Rad Controls for WCF Q1 2012.

Thank you

Getting Started tutorial

Hi,

This looks like a great control. Well done for creating it.

Just working through the Getting Started tutorial http://www.telerik.com/help/wpf/radganttview-getting-started.html , however, when I run it the Collection isn't binding to the control. It doesn't display the Tasks as shown. Could you please post the complete C# code for me to check?
Thanks.
