Hello,

I have created an application using the ScheduleView control and would like to persist the appointments.  If I try to use typical serialization methods, I get an exception saying that AppointmentBase is not serializable.  Does anyone know what the best approach is to save appointments to a file?

Thanks,
Mark

Hello,

I need to place edit and delete buttons upon display of the appointments/scheduler, to make the scheduler neat, I would like to disable/override mouse over event, so that the little "x" button wouldn't display anymore.

Appointment template editing can be done to insert the edit/delete buttons, but I don't know how to go about overriding the mouse over event on the appointment control. If anyone can assist me how to do it or give me a different way of looking at it. A sample code would be appreciated.

I would like the mask of a maskedtextbox to be bound to a dropdown or other on the viewmodel parent in a gridview.

I need to be able to switch between hh-mm-ss input and mm-ss input.

How do I implement this??

Hi.

I am loading a bar chart with data from an SQL connection. I am colouring the bars using the following:


I need the colour of a bar to change when I move my mouse over it and change back when I move away from it. It shouldn't change back to its original colour if I click on it. How do I accomplish this?

Thanks.

In my RadGridView I'm getting an invalid cast exception from CalculateAggregates when my aggregate function defined below is invoked:


Any suggestions as to why?

Also, on another note, would the following be valid? (I'm trying to build this Select expression on the fly using Dynamic Linq Library)

When I drag between two list boxes the mouse location and the start of the cue arrow (with the Icon) is offset a couple of inches down and to the right and it seems to offset the target location too..
2011 Q1 version. Vanilla DragTemplate 

 

 

<DataTemplate

x:Key="DragTemplate">

</DataTemplate>

Thoughts?

 

 

I'll add a screen shot if I figure out how to do that..

Hello,
I use RadGridView with DetailsPresenter together and I want to have DetailsPresent permanently displayed, even if no row is selected or datasource is empty (displayed controls can be empty and non editable in this case).
Thank you very much.

WPF Q2 2010 SP1

Dear Telerik,

I've updated our application to the .Net 4 version or Q3 WPF, i'm using the trial whilst the full version is being purchased. (2010.3.1119.40)

Our app was built using Q1 2010. 

I've updated the assemblies, and now the databinding for telerik controls has stopped working.  Lets say I have a view model with a bunch of properties, half of which are bound to telerik controls, and half of which are bound to standard controls. They are all bound to update their source on PropertyChanged. The standard controls still update their view model property, but the telerik controls do not.

help!

thanks
Pete

I'm trying to show only the major ticks and hide all the minor ticks between them, I have set the following properties in my xaml file:
On the AxisX, I set AutoRange="False", MinorTicksVisibility="Hidden", yet all the minor ticks are still showing up. Suggestions?
