Several Questions!
Hi, I am wondering, why ScheduleView is so much different to Scheduler?

So I have some questions:

1) Is there a way that ScheduleView's Timeline View (which is completely different) has the same look as the Scheduler's Timeline View?
2) The Scheduler provides events, which are fired, when the View Mode is changed (ActiveViewDefinitionChanged), or when the Selected View Start Date changed (SelectedViewStartDateChanged). Where are these events in ScheduleView?

Please answer me as soon as possible.

Thanks,
Ronald

ItemToolTip Problem with DataFormat
Hey,

I can't display the correct x-axis date value in the itemtooltip.
Here are the interesting facts for you...

I have a chart with thousands of points so i use:
<telerik:AxisX AutoRange="True"...


That's why in my ItemToolTip the first value works and the last not (because of this link this link):
<telerik:LineSeriesDefinition ItemToolTipFormat="#X --> #DATAITEM.Date or #DATAITEM.Date{MM/dd/yyyy}"...


But I can't use #X because it's from double type and the result is something like "42k" - but not a date!

What kind of solution you can offer for my problem? Is there a posibility to convert the double to string inside xaml?
(i can't use codebehind...)

P.S. Sorry but I realized to late that I've posted this thread in WPF - its for Silverlight!!!

Misplaced gridview row after refreshing
Hello :)

I have found a problem that goes like this:

I have a gridview that is bound to a observable collection of business objects.
The gridview properties:

<telerik:RadGridView x:Name="ReservasGridView"
                Margin="0"
        IsReadOnly="False" CanUserFreezeColumns="False" CanUserInsertRows="True"
        SelectionMode="Single" AutoGenerateColumns="False"
                IsFilteringAllowed="False" ShowGroupPanel="false" MaxHeight="768"
        IsSynchronizedWithCurrentItem="True"
>

Everything works as expected, but when I edit and commit an existing row, the first row of the gridview renders a few rows down. This not happens all the time, but it certainly happens, and I don't know why.

I have attached a jpg file showing this behavior.
I hope you can help me.

Best regards
Jorge

[Solved] interactivity issue
Hi there,

after updating to the q1 2011 release the interactivity feature is not working anymore. even in your controls demonstrating app.

please see attached screenshots.

picture 1: 2 countries are selected, nothing happens in the chart
picture 2: the mouse is over a red bar, no dimming of the others series

this bug occurs also in my own project using the chart component and 

var ds = new DataSeries();
ds.Definition.ShowItemToolTips = true;
ds.Definition.InteractivitySettings.HoverScope = InteractivityScope.Series;
ds.Definition.InteractivitySettings.SelectionScope = InteractivityScope.Series;

it works in the previous release. is this a bug or a feature? ^^

best wishes,

Chart

[Solved] Setting the Culture

Hello,

per default the culture of the RadMaskedNumericInput is set to en-US, changing that to a suitable value initially is easy enough. But how do I use the system-culture instead?

Setting the culture for every single control (and there will be hundreds of them) when the program is started is hardly the way to go. I tried using the value "(Standard)" from the selection of cultures available in the culture-property, but that is not an excepted value for that property.

I'm currently using the trial version of the 2011 Q1 release.

System.NullReferenceException in 2011.1 315
Last night I downloaded and installed the RadControls for WPF 2011.1 315 (Mar 16, 2011). The upgrade wizard would not allow me to upgrade my project to this version, it would only allow me to select 2010 Q3, so I manually browsed to the DLLS and then upgrade from it. (C:\Program Files (x86)\Telerik\RadControls for WPF Q1 2011\Binaries\WPF)

Now, when I rebuild my project (which was working just fine) I get the following error:

System.NullReferenceException
Object reference not set to an instance of an object.

GenericExpressionDark.xaml error after Q3 upgrade
Upgraded my VS 2008 WPF project (two, in fact) with the Q3 release today using the Upgrade Wizard. Now when I switch to the Design view of any page I get the following error:

Error   1   '/Telerik.Windows.Controls;component/Themes/GenericExpressionDark.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. '/Telerik.Windows.Controls;Component/themes/Expression/Dark/BusyIndicator.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Could not load type 'Microsoft.Windows.Design.Metadata.ProvideMetadataAttribute' from assembly 'Microsoft.Windows.Design.Extensibility, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

I'm not using GenericExpressionDark.xaml anywhere in my project, so I'm just a little confused.

Muliple items keep selecting even with SelectionMode="Single"
Hi there, 

I am using a RadGridView, here is the XAML

<telerik:RadGridView Grid.Row="1"
                            Grid.ColumnSpan="3"
                            SelectionMode="Single"
                            IsReadOnly="True"
                            Name="radGridView1"
                            ItemsSource="{Binding Path=ModelCodeList}"
                            SelectedItem="{Binding Path=SelectedModel, Mode=TwoWay}"
                            AutoGenerateColumns="False"  >
           <telerik:RadGridView.Columns>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding Code}" Header="Model"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding ID}" Header="ID"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding OemName}" Header="OEM Name"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding ModalityCode}" Header="Modality Code"/>
               <telerik:GridViewDataColumn DataMemberBinding="{Binding Active}" Header="Model Active"/>
           </telerik:RadGridView.Columns>
       </telerik:RadGridView>

As you can see I am binding the selected item, I followed the example from the code download in this (http://www.telerik.com/community/forums/wpf/gridview/select-a-row-from-viewmodel.aspx) post. I works the first time no problem... I put a breakpoint in my view model and I can see my SelectedModel getting set. The problem is that I can't unselect the first item and have it set the second item. At this point I am stuck - here is the pertinent code from the view model.

public Model SelectedModel
   {
     get { return selectedModel; }
     set
     {
       if (selectedModel != value)
       {
         selectedModel = value;
       }
       RaisePropertyChanged(() => this.SelectedModel);
       AddSelectedModelCommand.RaiseCanExecuteChanged();
     }
   }


What is does is keeps highlighting rows - even though I have SelectionMode="sinlge" - Uhm? Any suggestions? I attached a screen capture to show what I mean - see all the highlighted rows?

Thanks!

** Also - The only difference I can see between my project and the sample is that we are "Target Framework:" is set to ".NET Framework 4" and your project is being built as ".NET Framework 4 Client Profile"

[Solved] Calendar Startdate

Hello,

I'm currently evaluating the trial version of RadControls for WPF 2010_3_1314.

I have found solutions for my other problems with the RadDateTimePicker, but couldn't find anything on opening the calender to the current date for the WPF version.

In my window I have a RadDateTimePicker to select the birth-date of a person, bound to the entity selected from a SQL-database.

When a new person is added it has no birth-date, as this is not a mandatory field.

In everyday use the calendar will hardly be needed, as it is simpler just to type the birth-date instead of navigating there.

However it would still be nice to open the calendar to the current date instead of 1/1/1800, the minimum allowed date I have set.

How can I open the calendar to the current date, without it actually being selected?

Thanks
