Hi!

Is there any way to make an tab don't scroll when we have too many tabs on screen?

I want to left the first tab always visible, even when scrolling.

Something exactly like the attached image.

Thank you!

Subclassing RadRibbonTab

I'm trying to subclass the RadRibbonTab as a custom UserControl to be able to use PRISM to navigate to a specific ribbon tab.

However the subclassed RibbonTab never appears in the tab bar of the ribbon. I created a sample to demonstrate the problem:

MainWindow.xaml:

<Window x:Class="RadControlsWpfApp1.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:local="clr-namespace:RadControlsWpfApp1"

Title="MainWindow" Height="350" Width="525">

<telerik:RadRibbonView>

<telerik:RadRibbonTab Header="Tab 1">

<telerik:RadRibbonGroup Header="Group 1">

<telerik:RadRibbonButton Size="Large">Button 1</telerik:RadRibbonButton>

</telerik:RadRibbonGroup>

</telerik:RadRibbonTab>

<local:UserControl1 />

</telerik:RadRibbonView>

</Window>

UserControl1.xaml:

<telerik:RadRibbonTab x:Class="RadControlsWpfApp1.UserControl1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="300"

Header="Tab 2">

<telerik:RadRibbonGroup Header="Group 2">

<telerik:RadRibbonButton Size="Large">Button 2</telerik:RadRibbonButton>

</telerik:RadRibbonGroup>

</telerik:RadRibbonTab>

UserControl1.xaml.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

using Telerik.Windows.Controls;

namespace RadControlsWpfApp1

{

/// <summary>

/// Interaction logic for UserControl1.xaml

/// </summary>

public partial class UserControl1 : RadRibbonTab

{

public UserControl1()

{

InitializeComponent();

}

I'm probably missing something obvious, however I don't know what. Thanks for your help.

[Solved] IsTabStop doesn't work as expected?

Hi,
I'm using Telerik controls with version 2013.2.724.40, and VS 2010.
In the following code example, I'd like to use tab to navigate only between the 3 TextBoxes. IsTabStop is set to false, but the tab still stops at the RadExpander, is it an expected behavior?

Thanks.
Gong

Add property definitions dynamically from code-behind

I have a situation where I would like to be able to add property definitions from code behind, however it doesn't appear to be working properly.

Here's what I have: I made a custom object for use in xaml called a PropertyDefinitionList:

public class PropertyDefinitionList : List<Telerik.Windows.Controls.Data.PropertyGrid.PropertyDefinition>

{

public PropertyDefinitionList() { }

}

In a resource dictionary I instance such a list like follows:

<local:ObjectPropertyFilterList x:Key="PropertyDefinitions" >
    <propertyGrid:PropertyDefinition Binding="{Binding Name}" />
    <propertyGrid:PropertyDefinition Binding="{Binding ID}" />
</local:ObjectPropertyFilterList>

I get a reference to this list in my code behind and call it PropertyList. At a certain 
point I want to the property definitions to the .PropertyDefinitions collection on the 
RadPropertyGrid, so in the function that does it I have the following code:

rpg1.PropertyDefinitions.AddRange(propertyDefinitionList1);
rpg1.item = targetitem;
However when the code executes I get two blank definition entries in the property grid 
display. There is no display name nor value. The properties definitely exist in the object 
being assigned to "item", but its like these property definitions don't get their binding 
set. In another thread it was stated that property definitions have their binding 
evaluated when the .item property changes, so what is happening (or not happening) here? I 
figure I must be doing something wrong.

Thanks!
