Appointment Style Selector

[Prachi]

Hi Support,


I tried using appointmentstyle selector as mentioned on telerik site and i tried to set the visibility property of appointmentitem;
but I am getting error as 'Xaml Parse exception : Line 0 Position 0'.
Here is the code for your reference.

<

 

 

Style x:Key="AppointmentTypeStyle" TargetType="telerik:AppointmentItem">

 

 

 

 

<Setter Property="Visibility" Value="Visible"></Setter>

 

 

 

 

</Style>

 

<

 

 

local:AppointmentStyleSelector x:Key="ItemStyleSelector"

 

 

AppointmentTypeStyle

 

 

 

 

 

="{StaticResource AppointmentTypeStyle}" />




Thanks

Prachi

Hello Prachi,

From the code you have posted we can conclude that you should have no problems using the selector. Please, send us a reproducable sample, so that we can find out what has gone wrong.

As a side note, I would like to point out that it is not recommended that you use the Visibility property as a part of an appointment style. Switching between different Visibility values for the appointments might result in improper recycling and unexpected rendering of the appointment items.

Hi telerik ,

Here my requirement is to show those appointments for which resources are checked. Can you suggest me the peoper way to it.
And I am also grouping resources in two groups and trying to show child resources per group by setting the visibility property. but some times it does not display it properly. Please give me solution for the same.


Here I am attaching the code for resource grouping

XAML Code : 

<UserControl.Resources>

       <DataTemplate x:Key="DateGroup">
           <TextBlock Text="{Binding}" Width="70"></TextBlock>
        </DataTemplate>

       <DataTemplate x:Key="ResourceGroup">
           <CheckBox x:Name="resourceCheckBox" Content="{Binding}">
               <i:Interaction.Triggers>
                   <i:EventTrigger EventName="Checked">
                       <hms:EventToCommand Command="{Binding ResourceCheckedCommand, Source={StaticResource ViewModel}}" CommandParameter="{Binding ElementName=resourceCheckBox}" PassEventArgsToCommand="True"/>
                   </i:EventTrigger>
               </i:Interaction.Triggers>
           </CheckBox>
       </DataTemplate>
       <Style x:Key="AppointmentTypeTemplate" TargetType="telerik:GroupHeader">
           <Style.BasedOn>
               <Style TargetType="telerik:GroupHeader" >
                   <Setter Property="Visibility" Value="Visible"></Setter>
               </Style>
           </Style.BasedOn>
        </Style>
       <Style x:Key="VisibleResourceTypeTemplate"  TargetType="telerik:GroupHeader">
           <Style.BasedOn>
               <Style TargetType="telerik:GroupHeader" >

Hi Prachi,

Thank you for the supplied sources. However, display of a certain group or resource upon checking a CheckBox in a resource header is not possible with the current implementation of RadScheduleView, I am afraid.
