[Solved] Don't drag when selecting text with mouse

I have a RadListBox with DragDropBehavior, the RadListBox itemtemplates contain a textbox. I want the text in the textbox to be selectable using the mouse, but when I drag to select text, the item is dragged instead. Is it possible to disable drag within a control in an itemtemplate in a draggable RadListBox? I tried setting telerik:DragDropManager.AllowCapturedDrag="False" and telerik:DragDropManager.AllowDrag="False" on the textbox but that doesn't help.

Here's my little test project:

using System.Collections.ObjectModel;

namespace ListBoxTest

{

public partial class MainWindow

{

public MainWindow()

{

InitializeComponent();

DataContext = this;

MyCollection = new ObservableCollection<string> { "test text 1", "test text 2", "test text 3", "test text 4", "test text 5", "test text 6" };

}

public ObservableCollection<string> MyCollection { get; private set; }

}

<Window

x:Class="ListBoxTest.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"

Title="MainWindow" Height="500" Width="525">

<telerik:RadListBox

ItemsSource="{Binding MyCollection}">

<telerik:RadListBox.ItemTemplate>

<DataTemplate>

<Grid Height="50" Width="100" Background="LightBlue" telerik:DragDropManager.AllowCapturedDrag="True">

<TextBox

Text="{Binding .}"

VerticalAlignment="Center"

HorizontalAlignment="Center"

telerik:DragDropManager.AllowCapturedDrag="False"

telerik:DragDropManager.AllowDrag="False"/>

</Grid>

</DataTemplate>

</telerik:RadListBox.ItemTemplate>

<telerik:RadListBox.DragDropBehavior>

<telerik:ListBoxDragDropBehavior />

</telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

</Window>

How to hide horizontal scroll bar

Hello,

I'm trying to customize the style of the timeline by minimizing controls from the timeline.It will be embedded in a different control that will then perform the manipulation of zooming and scrolling.

1) I have successfully hidden the group header by modifying the TimelineItemContainer ItemsPanelTemplate TimelineItemGroupsPanel padding to be = zero

2) I have not been able to hide the small thin border item that still exists at the top of the timeline

3) I have not been able to hide the horizontal scroll bar at the bottom of the timeline.

I am using the implicit style method and have successfully completed #1.

[Solved] RadMap zoomlevel granularity

Is there any chance that we can get the zoomlevel changed to a double so that I can more precisely size my map? Or is there another way to achieve this? E.G. the difference between zoom level 7 and 8 on one of the supplied US state shapefiles is quite a lot. I'd like to be able to zoom in at, say 7.3 or 7.4.

Drag and drop in editable mode

Hi. I am using RadComboBox control in my project. Previously, the control was in non-editable mode (IsEditable="False") and drop functions worked fine.

<telerik:RadComboBox
IsEditable="True"
IsFilteringEnabled="True"
AllowDrop="True"
ItemsSource="{Binding Type.Items}"
DisplayMemberPath="DocumentId"
Text="{Binding Value, Mode=TwoWay}">
<i:Interaction.Behaviors>
<local:DropTargetBehavior DropCommand="{Binding DropCommand}" />
</i:Interaction.Behaviors>
</telerik:RadComboBox

When I set IsEditable to True then drop functionality has stopped working. In editable mode there is an "Input Area" overlay control and i cannot drop anything to RadComboBox. Can you suggest any working example for dropping something to RadComboBox in editable mode (IsEditable="True")?

ContentPresenter of RadRibbonButton has different alignment in Fluent theme

When I switched to Fluent theme all RadRibbonButtons direct content was aligned to the left instead of centered as it was previously in Expression Dark theme. The problem is, that ContentPresenter in StackPanel named FirstRowContainer has its HorizontalAlignment property set to Left. I don't know how can I change that to Center and I need your help to fix it. Direct content of buttons is TextBlock displaying Font Glyph. Here is sample code:

                        <telerik:RadRibbonButton x:Name="buttonLock"
                                                 Click="ButtonLock_OnClick"
                                                 IsEnabled="{Binding IsUiUnlocked}"
                                                 Size="Large"
                                                 Text="Lock">
                            <TextBlock Margin="2"
                                       FontFamily="{StaticResource TelerikWebUI}"
                                       FontSize="24"
                                       Foreground="#00BFE8"
                                       Text="{StaticResource GlyphLock}" />
                        </telerik:RadRibbonButton>
