Hello,

i'm currently using the ScheduleView for showing appointments on a touchscreen. I changed the theme of the ScheduleView so i could open the EditAppointmentDialog with a single tap. The first problem is that the EditAppointmentDialog only shows when i click on a certain area of the appointment. It seems like the frame of the appointment where it reacts to the tap is slightly moved down. I attached a screen with the appointment - the black border illustrates where i need to tap to open the dialog.
This problem only occurs only on the touchscreen though, if i run the application on a normal screen and select the appointments with a mouse it shows no abnormal behavior.
When i try to select the rows of the calendar or press buttons the click is recognized at the right location, so the probelm only occurs when trying to open the EditAppointmentDialog. This makes me think it is a problem with the control and not an issue with drivers or the touchscreen.

I also defined a custom ViewDefinition for a work week, from Monday-Saturday, which leads to my second problem. When i try to pinch within this ViewDefinition i get an InvalidOperationException with the Message 'TimeRulerMonthViewGroupItem' TargetType does not match type of element 'TimeRulerGroupItem'. I found a similiar issue in this thread: http://www.telerik.com/community/forums/wpf/scheduleview/crash-while-pinch-to-zoom.aspx - but the workaround that was posted there didn't work for me.

The exception details:

System.InvalidOperationException was unhandled
  HResult=-2146233079
  Message='TimeRulerMonthViewGroupItem' TargetType does not match type of element 'TimeRulerGroupItem'.

I have a situation where I need to base the grid on an observable collection and I want to auto generate the columns based on the values of the Period property of the collection. For example, given the following code I want the column headers to display 2013, 2014, 2015, etc.


Does anyone have any suggestions?

Hi,

I am new to Rad Controls/Diagram and would like some help if possible.

What I would like to do is cancel a connection between two items within the diagram based on the target's type.

Is this possible, if so, how would I go about it?

Thanks
Paul.

I'm trying to add a shape from code adding an element to the graphsource property.
Everything works as expected: the new shape is added to the diagram at position (0, 0) unless I set a different value.

Is it possible to compute a "meaningful" position using a layout algorithm?
Of course I can add the shape and then trigger a diagram layout, but this will affect the position of every shape...

Hi Telerik,

I have a few questions regarding the usage of the RadDocument.  According to my scenario I prepare different Documents in Designer (using RadRichTextBox) with Placeholders,  which are implemented with the InlineUIContainers and child TextBlock element,  and then this serialize document to HTML and retain in the Storage.
In the various Application background processes we use the prepared Doument "template" for generating HTML documents,  by replacing the Placeholders with the real-time data.
To do it, we try to deserialize the RadDocument from the HTML and then use RadDocument DOM model for easier and safer Placeholder replacement operation.  The only way we found to do it on Application Server is to use methods  HtmlFormatProvider.Import, HtmlFormatProvider.Export. BUT they are not designed to be used in a such way as they expect to be run only in STA thread, so we got an exception:

InvalidOperationException with message "The calling thread must be STA, because many UI components require this."

Creating a dedicated STA thread for processing each documents works only under non-stressful conditions, and definitely failed on contrary with the confusing exception:

System.ComponentModel.Win32Exception (0x80004005): The operation completed successfully

Could you please suggest any way to overcome our problem, or suggest another approach for working with RadDocuments in background processes?

 

Thanks

HI,

I use this XMAL :

but the appointments will be stretched... (see attachment)
I use my own AppointmentItemContentTemplate with a TextBlock and a ProgressBar and set the MinAppointmentHeight="40"

How yould I fix this issue?

Thx

Hi,

For my purposes, I am using RadRichTextBox instead of RadTextBox in order to take advantage of the spell check, where incorrect words get underlined.



I need to create something similar to an EmptyContent property in RadMaskedTextInput control.  Can someone suggest how to such behavior to the RadRichTextBox?

Thank you in advance,



Michael

Hello,

It seems to have a bug with async binding and GridView.

Indeed when i create a grid view with synchronous binding like that :


Everything works well.

But when i try to make Asynchronous Binding (because the property AssetAnalysers take time to load) like that :


At the first loading the four columns are well generated but when my property AssetAnalysers change (it's a INotifyChangedProperty), the binding seems correct but my columns are not generated. So, the GridView looks like empty (but i have rows).

Where is the problem ?

By the way what's the difference and the correct using of UniqueName, DataMemberBinding and DataMemberPath Properties when you have already a binding on ItemSource.

Thank you in advance for your answer.

I have a WPF application that uses the Rad Controls for WPF.  On one of the windows, there is a RadDateTimePicker:

   

Everything works fine when the machine's culture is set to en-US.  However, when I change my machine's culture to es-CL (Chile), the text "Enter Date" that appears in the control when it is empty does not get translated to Spanish.  I still see "Enter Date".



When a date is displayed in the control, it's in the proper format for that region.  How do I get the "Enter Date" to display in Spanish?

I have created my image property in my view model and can see the correct format provider is being used and populating my RadBitmap property but the binding does not work on the RadImageEditorUI control.

 

Is binding working for this control? If so, please provide a MVVM example because the documentaiton for this has no binding examples.
