Some questions regarding 24-hour format and NavigationHeader

Hi,

1. In an earlier forum thread, you stated that 24-hour format functionality was coming soon. Is this functionality implemented atm? If so, how do I change my ScheduleView to use the 24-hour format?

2. In the application I am developing at the moment, I really want to be able to place the buttons (ex. the forward and backward buttons) in the NavigationHeader at some other place on the outside of the ScheduleView. Is this possible in the current version of ScheduleView?

As an elaboration of question 2, I basically want to only use the schedule-part of the ScheduleView in my application. The navigation buttons in addition to the appointment creation-, editing-, and deletion-functionality should be handled in my own code.

Root Compass Events VS. Compass Events

In telerik:RadDocking, we can either specify in XAML or in CS if we want to turn off/hide items on the compass. Unfortunately what I want to do doesnt seem to be so straight forward.

Is it possible to either remove items from the central docking preview, while leaving their counterpart on the outer docking preview? (Ie remove the left arrow on the center of the screen but keep the left arrow on the left edge of the window). This would be much easier if i could insert an image in the code snippet!

Anyway, if this cannot be done, for any reason, an alternate solution that would help my cause would be a code behind solution maybe in the PreviewWindowClose event or something, so that I could just tie the two compass events together, ie the center of the window left facing dock arrow would dock the panel on the left edge of the screen, in the same place that the left dock arrow on the edge of the screen would dock it.

Any tips or hints to get me going in the right direction here would be greatly appreciated, thanks!

Appointment Persistence

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

mouseOver event override

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.

Colouring bars individually

Hi.

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

<Setter Property="Template" >

<Setter.Value>

<ControlTemplate TargetType="telerikCharting:Bar">

<Rectangle x:Name="PART_DefiningGeometry"

Height="{TemplateBinding ItemActualHeight}"

Width="{TemplateBinding ItemActualWidth}"

Style="{TemplateBinding ItemStyle}" Fill="Red">

</Rectangle>

</ControlTemplate>

</Setter.Value>

</Setter

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.
Anand

Dynamic Linq throws invalid cast exception

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

var totalColumnAggregate = new AggregateFunction<DataRow, int?>

{

AggregationExpression = target => target

.AsQueryable()

.Select("new(it[\"Foo\"] AS Foo)")

.Cast<int?>()

.Sum()

};

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)

.Select("new(it[\"Foo\"] AS Foo) + new(it[\"Bar\"] AS Bar) + new(it[\"FooBar\"] AS FooBar)")

Odd Drag Behaviour WPF

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..

Permanently displayed DetailsPresenter

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.

DataBinding broken in NumericUpDown in .Net4 version

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
