I have a RadCartesianChart with a vertical linear axis.

I want to be able to click on the axis and show a dialog.

I have got it working on the MouseLeftButtonUp event – but it only triggers when I click the labels – and not the background. I have tried to style the axis – but with no luck.

Hello,

 

I've created a custom resourcetype "rep" and subsequent resources (reps) that are currently different categories on my scheduleview. I now have the view that I want, but i don't know how to add data to the rep property of an appointment so it will be shown in the proper category. Unsure on whether to create my own custom appointments or if this can be bound as is.

 

Thanks

Hi. I have a RadTabControl, wich ContentTemplate is a static resource with a DataTemplate like this:

 

        <DataTemplate x:Key="TabItemContentTemplate" >
            <ContentControl prism:RegionManager.RegionName="{Binding RegionName}"/>
        </DataTemplate>

My item view model has a Header property and a RegionName property. All I want is to know the exactly moment all the templates are applied in the RadTabControl, so I can call the RegionManager to create a view inside.

I've tried RadTabControl.Loaded and may others, also have tried to locate ContentPresenter named ContentElement and attach to the Loaded event, but even there the content control is not yet created.

 

Any ideas? Thanks in advance.

 

David.

Hi,

I'm creating a ComboBox that contains a Dictionary<byte,string> (for ex.) and ClearSelectionbuttonVisibility = Visible.

It's all ok, but if I click on "Clear Selection", it gives me ad error (that I attached).

I had to declare my property SelectedItem as KeyValuePair<byte, string>.

Now, I think that the reason's error is that KeyValuePair<byte,string> is not nullable, then?

How can I do use Dictionary in this context?

<!--My ComboBox for Dictionary-->
<telerik:RadComboBox ItemsSource="{Binding MyItems}"
                     SelectedItem="{Binding SelectedItem,Mode=TwoWay}"
                     DisplayMemberPath="Value"
                     SelectedValuePath="Key"
                     Style="{StaticResource FieldLongComboBoxStyle}"/>
                      
 
<!--Style-->
<Style x:Key="FieldBaseComboBoxStyle" TargetType="telerik:RadComboBox" BasedOn="{StaticResource RadComboBoxStyle}">
    <Setter Property="Margin" Value="5"/>
    <Setter Property="ClearSelectionButtonVisibility" Value="Visible"/>
    <Setter Property="ClearSelectionButtonContent" Value="Clear selection"/>
    <Setter Property="TextSearchMode" Value="StartsWith"/>
    <Setter Property="EmptyText" Value="Valore non selezionato"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
    <Style.Triggers>
        <DataTrigger Binding="{Binding CantUpdateModel}" Value="True">
            <Setter Property="IsReadOnly" Value="True"/>
            <Setter Property="IsEditable" Value="False"/>
            <Setter Property="IsHitTestVisible" Value="False"/>
            <Setter Property="FontWeight" Value="Bold"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding CantUpdateModel}" Value="False">
            <Setter Property="IsReadOnly" Value="False"/>
            <Setter Property="IsEditable" Value="True"/>
            <Setter Property="IsHitTestVisible" Value="True"/>
            <Setter Property="FontWeight" Value="Normal"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

I need to have multiple line spread to the depth of Z-Axis so that they don't overlap. Is Z-Axis supported by 3D chart? Can you give an simple example of this implementation? Your sample only shows 3D line but we need mutiple 2D lines spread to the depth of Z-Axis.

Thanks,
Jessica

First of all sorry if this question is already answered or it is very dummy.

 

I was using several RadTabControls in my application, but I've reached a point that I need to use a view model istead of a RadTabItem and create them in codebehind on certain conditions for one of the RadTabCotrols.

There is other function that does run through every RadTabControl retrieving all the RadTabItems by looking at the Item property. But it happens that one of my RadTabControls has a custom viewModel, so the cast to RadTabItem fails.

I suppose that it is very logical to get the ViewModel from Items property when you have defined to have a viewmodel and want to run over all items, but I wonder if there is a generic way (accessor, list) of getting just the RadTabItem control that wraps the custom viewmodel and use the same method of running through all RadTabItems for all RadTabControls.

 

Thanks in advance.

 

David.

Hello. In my application I need to do zooming in, zoming out and panning with mouse and without scrollbar. I've been trying to found about it in forums, but if I find something there then these are examples for Silverlight and use obsolete (old) versions of Telerik. Please give me an example for WPF of zooming in, zoming out and panning with mouse and without scrollbar for latest (newest) version of Telerik.

Very annoying to have to manually remove all Telerik WPF references and add the newer version to every single project of mine everytime there is a new version of the WPF controls released. There should be an update utility like what Telerik WinForms is packaged with.

Hello,

Is it possible to show just the recurrence dialog, without creating any scheduleview objects as well as bypassing the appointment dialog?

There is this: RadScheduleViewCommands.EditRecurrenceRule.Execute(null, scheduleview);

But i guess it requires the scheduleview object anyway?

I'd rather have something similar, but be able to pass an Appointment or RecurrenceRule objects directly.
