How to disable tabs on a bound collection

[Asela]

Hi there,

I have a dynamic collection which I bind to the tab control, however, I would also like to be able to enable / disable the tabs based on some criteria, however, I am unsure of what to  bind to so I Can disable tabbing to the control.

I followed your basic demo for binding to a collection please see code below

<Grid>
        <Grid.DataContext>
            <WpfApplication3:MainWindowViewModel/>
        </Grid.DataContext>
        <telerik:RadTabControl ItemsSource="{Binding People}" >
            <telerik:RadTabControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}"/>
                </DataTemplate>
               
            </telerik:RadTabControl.ItemTemplate>
            <telerik:RadTabControl.ContentTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Age}"/>
                </DataTemplate>
            </telerik:RadTabControl.ContentTemplate>
        </telerik:RadTabControl>
    </Grid>

Thanks

Hi Asela,

 Supposing you are following the approach demonstrated in this help article, you can introduce boolean property in the Person class:

public class Person
 {
     public Person(string name, int age)
     {
         this.Name = name;
         this.Age = age;
     }
     public string Name
     {
         get;
         set;
     }
     public int Age
     {
         get;
         set;
     }

     public bool Enabled { get; set; }
 }

and bind it to the IsEnabled property of the corresponding RadTabItems via StyleBindings:

<Grid.Resources>
           <local:ViewModel x:Key="DataSource" />

           <Style TargetType="telerik:RadTabItem">
               <Setter Property="IsEnabled" Value="{Binding Enabled, Mode=TwoWay}" />
           </Style>

           <DataTemplate x:Key="ContentTemplate">
               <Grid>
                   <TextBlock Text="{Binding Age}" />
               </Grid>
           </DataTemplate>

           </Grid.Resources>

You can find this realized in the attached solution. Please let us know if this is what you need. Greetings,
