VisibleRange.Start/End and VisibleRangeStart/End are different from within the ScheduleView_VisibleRangeChanged

Hi,

I was assuming that "VisibleRange.Start" and "VisibleRangeStart" would return the same value. But sometimes inside the VisibleRangeChanged event, they show different values.

VisibleRange.Start/End has the new visible range after the event and VisibleRangeStart/End has the last visible range before the event. Is this right?

Thanks,
Manoj

The ClockStyle property isn't documented

In previous versions, there used to be a ClockPanel property to customize the drop-down clock panel. In the newest version, this is marked as deprecated. But there is no or little information on how to use the new ClockStyle property.

I'm looking to change the number of columns in the drop-down ClockPanel dynamically.

Old code:

<telerik:RadTimePicker x:Name="stopTime" >

<telerik:RadTimePicker.ClockPanel>

<ItemsPanelTemplate>

<panels:RadUniformGrid x:Name="stopTimePanel" Columns="6" />

</ItemsPanelTemplate>

</telerik:RadTimePicker.ClockPanel>

</telerik:RadTimePicker>

It is my understanding the the new code would look something like this:

<telerik:RadTimePicker x:Name="stopTime">

<telerik:RadTimePicker.ClockStyle>

<Style TargetType="telerik:RadClock">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate>

<panels:RadUniformGrid x:Name="stopTimePanel" Columns="2" />

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</telerik:RadTimePicker.ClockStyle>

</telerik:RadTimePicker>

But this example doesn't work. The dropdown list simply refuses to show. Can you provide an example of a working ClockStyle that lets you set the displayed number of columns?

Undo or History Stack object

Hello,

I'm currently using a single RTB instance to accommodate multiple documents without any issues. For obvious reasons the Undo/History stack for each instance gets lost between document loads. Is there any kind of Undo or History Stack object property of the RichTextBoxUI that I can bind to my ViewModel (and indirectly my data model) to carry this information around?

Any help would be greatly appreciated.

Thanks,

RichTextBox

AvailableFilters in RadMap

Hi guys,

I've been experimenting with the WPF RadMap control for a couple of days and everything is working as it should, but I'd like the user to be able to filter the search results based on the AvailableFilters data which is returned from Bing. (This can be seen if we examine the SOAP response in Fiddler).

I've got filtering working via the FilterExpression class, I just need to be able to read the AvailableFilters data - but I can't seem to find it in inside the SearchCompletedEventArgs. I've noticed that you have a AvailableFilters class in the BingSearchService namespace [1], which suggests this is possible. Perhaps someone could point me in the right direction?

I'm using the BingSearchProvider with the query "restaurants in colchester" as my example. This should give 8 available filters. My RadMap version is Q3 2010 SP1.

Best regards

How do I make the indicator refresh mode "Average" work?

I have a guage that gets updated once per second. The value has some flux to it, but I don't want the indicator to jump if the value drops a bit on one sampling out of like 10. What I'm looking for is a steady average of values. What do I need to do to make this average work automatically? Obviously, I could record the past x number of samplings and average them myself, but I understood the indicator refresh mode to behave this way when its set to average. What I'm witnessing now is an indicator jump when I get values such as these:

Values:

89
88
92
93
90
88
70 <----Big indicator jump here
88
89
92

I'm just looking to smooth this out a bit. What are your recommendations?

Thanks...

Testing with White

We use "White" for our UI testing.
I can not find my RadMaskedTextBox by its AutomationId that is a control's name for WPF controls.
TextBox myTextBox = _myWindow.Get<TextBox>("textBoxName");

All RadMaskedTextBox have the same AutomationId and it is "PART_ExtendedTextBox"
Does anybody use "White" for UI tests? How do you work around this?

RadGridView.RowDetailsTemplate click event

I have a button inside a RowDetailsTemplate. Hover and click events don't flow to the button, but result in the selection of the row. Is this normal? How can I make my button handle them instead? My button extends from the WPF Button class, so I'd assume it already has handlers and such...

GridViewComboBoxColumn's DataContext problem in a radGridView

Hi,

I've a problem, I don't know if it's a bug, but it's blocking for me:

I've a Window, which provides some ObservableCollection to my users controls through binding

in my user control, I've a RadGridView which is bound on a property of my code behind. This property use objects issued from the binding with the window.

I've a collection of objects which is displayed.

The problem is:

I'm now trying to add a GridViewComboBoxColumn, but if I put a converter on itemsource only to see which context I've:

<telerik:GridViewComboBoxColumn Header="Channel" DataMemberBinding="{Binding Channel}" ItemsSource="{Binding Converter={StaticResource Watcher}}" Width="2*"/>

I get the context of the Window!

Why??? This should be the datacontext of the usercontrol!

I double checked, In my code behind of my code behind, I've never any reference of the window, or somewhere where I could have bound the datacontext to the window?

I've a "theGridName.DataContext = this;" in the userControl's code behind, nothing else.

Thank you for your help
