Is there a 

telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True" that works on the RadListBox (not only the RadComboBox)?

So a :ComboBoxToolTipHelper.ShowToolTipOnTrimmedText that works on the RadListBox?

Or another way of achieving it on the RadListBox?

Background:

I tried with a behavior on the row data template but it conflicts with the drag and drop by causing exceptions during the drag and drop (but that would incur another question thread).  I am just writing this to say i tried this avenue.

Right now my RadLitBox looks as follows:

<telerik:RadListBox x:Name="RLB_Source"   
                                        VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
                                        ItemsSource="{Binding SourceSplitList, Mode=TwoWay}" 
                                        SelectionMode="Multiple"  
                                        telerik:ListBoxSelectedItemsBehavior.SelectedItemsSource="{Binding SelectedSourceItems}"
                                        DisplayMemberPath="Name" 
                                        AllowDrop="True" 
                                        ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                                        ScrollViewer.VerticalScrollBarVisibility="Visible"  
                                        Style="{StaticResource RadListBoxStyle}" 
                                        telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
                                        ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}" 
                                        >

Because of the lines:

                                        telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
                                        ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}" 

There is a tool tip showing the text of every RadListBox row - and not only where the text is trimmed.

How is the text trimmed? Short answer: i have a telerik:RadListBoxItem style template where text trimming is set as below:  

         <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>

Here is the entire control template:

 <ControlTemplate TargetType="{x:Type telerik:RadListBoxItem}">
                    <Border
                                x:Name="Bd"
                                Padding="{TemplateBinding Padding}"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                SnapsToDevicePixels="true">
                        <ContentPresenter 
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                   SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                                   >

                            <ContentPresenter.Resources>
                                <Style TargetType="TextBlock">
                                    <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>
                                    <Setter Property="TextWrapping" Value="NoWrap" />
                                    <Setter Property="Text" Value="{Binding Name}" />
                                    <Setter Property="ToolTipService.ToolTip" Value="{Binding Name}" />
                                </Style>
                            </ContentPresenter.Resources>
                        </ContentPresenter> 
                    </Border>  

</ControlTemplate>

Trimming is set on the TextBlock that appears (implicitly by Telerik) in the Contentpresenter.

 

The whole styling is below if relevant for answering the question:

My RadListBox has this style:

 <Style x:Key="RadListBoxStyle" TargetType="{x:Type telerik:RadListBox}">
        <Setter Property="AlternationCount" Value="2" />
        <Setter Property="ScrollViewer.CanContentScroll" Value="True" />
        <Setter Property="VirtualizingPanel.ScrollUnit" Value="Pixel" />
        <Setter Property="VirtualizingPanel.VirtualizationMode" Value="Recycling" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="BorderBrush" Value="{StaticResource Gray}" />
        <Setter Property="Background" Value="{DynamicResource White}" />
        <Setter Property="SelectionMode" Value="Multiple" />
        <Setter Property="FontSize" Value="12pt" />
        <Setter Property="FontFamily" Value="{StaticResource SourceSansPro-Regular}" />
        <Setter Property="Foreground" Value="{StaticResource Brand Default}" />
        <Setter Property="Margin" Value="0,2,0,0" />
        <Setter Property="HorizontalAlignment" Value="Stretch" />
        <Setter Property="ItemContainerStyle" Value="{StaticResource DefaultDragDropRadListBoxItemStyle}" /> 
    </Style> 

 

In the the above style there is an ItemContainerStyle.  Here it goes:

        

  <Style x:Key="DefaultDragDropRadListBoxItemStyle" TargetType="telerik:RadListBoxItem">
        <Setter Property="BorderBrush" Value="{StaticResource 'Gray Light'}" />
        <Setter Property="BorderThickness" Value="0,0,0,1" />
        <Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" /> 

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type telerik:RadListBoxItem}">
                    <Border
                                x:Name="Bd"
                                Padding="{TemplateBinding Padding}"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                SnapsToDevicePixels="true">
                        <ContentPresenter 
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                   SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                                   >

                            <ContentPresenter.Resources>
                                <Style TargetType="TextBlock">
                                    <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>
                                    <Setter Property="TextWrapping" Value="NoWrap" />
                                    <Setter Property="Text" Value="{Binding Name}" />
                                    <Setter Property="ToolTipService.ToolTip" Value="{Binding Name}" />
                                </Style>
                            </ContentPresenter.Resources>
                        </ContentPresenter> 
                    </Border>

We have created an app that allows the user to create templates using the diagram control, and then bind data (several records) to print / export to PDF.  The bind operation does not need the diagram to be visible, and its a desired behavior, the user can click a button and we work with the diagram in the background (bind each record, export the image) without the user seeing the diagram loading every record.

The issue we have encountered is that if the diagram has collapsed visibility or is not visible, the items do not render (they have their isLoaded property set to false). This might be an optimization on the Diagram to render only visible items, however its causing an issue for our use case. 

How do we make the diagram load and render all items even when its not visible?  (Or what trick can we use to keep the diagram hidden and yet have it render?)

We also wish to optimize the loading speed in this scenario, suggestions to speed up diagram loading saved items would really help us, as you can imaging we do not need any UI features such as Dragging, Copy/Paste/Undo etc. in the data-bind and export mode.

Hi,

I have created a RadGridView with a couple of columns (one of them being GridViewSelectColumn). I have also created a GroupDescriptor with GroupHeaderTemplate and I would like to add a GridViewCheckBox to the GroupHeaderTemplate, so I can select all items in a particular group by one click, however, the GridViewCheckBox is not enabled. I tried different properties on the control, but none of them works for me. 

If I add just a CheckBox then it works, but it does not have the style I need and I would not like to reproduce the Style already present on GridViewSelectColumn.

Can you advise how to enable the GridViewCheckBox ?

Thanks

I'm using the Prism 8 template pack to create a WPF solution.
I'm adding the Nuget package 'Telerik.UI.for.Wpf.60.Trial' (No Xaml)
I'm adding the solution of KB (Using RadWindow with Prism 7 | Telerik UI for WPF)

Now I have problems to start the solution.

No error, but no viwe is visible.

If I use the Nuget package 'Telerik.UI.for.Wpf.60.xaml.Trial' (with Xaml) I have no problems.

Why I have problems with the 'no xaml' version?

Attached a demo with PRISM 8

Hi,

1-Is it possible to set the RadDesktopAlert height automatically based on the content text?

2-After showing RadDesktopAlert, if we move the mouse over RadDesktopAlert, the background color will change. What should I do if we don't want the background color to change?

3-After RadDesktopAlert is shown, if we move the mouse over RadDesktopAlert, the text of the content will be underlined. What should we do if we don't want this underline to be displayed?

4-After RadDesktopAlert is displayed, if we move the mouse over RadDesktopAlert, a line will be drawn under the content text and RadDesktopAlert will be closed by clicking on the content text. What should I do if RadDesktopAlert is not closed by clicking on the content text?

5-If the Windows theme is in High contrast, it will not be applied to RadDesktopAlert. If we want the background to be black in the contrast theme and the content to be displayed in white, how should we do this?

6-How to change the color of the header & content text?

Thank you

I coded the following XAML

<FileDialogs:ExplorerControl x:Name="ecDeployStuff" HorizontalAlignment="Left" Margin="12,28,0,0" VerticalAlignment="Top" CurrentDirectoryPath="C:\lala\Main\zzzDevelopment\abc" />

when I launch the WPF app it shows as the C: drive

am I missing another property to make the CurrentDirectoryPath work?

I would appreciate help on how to change 12AM to Sunday, Monday, etc.

And how to change the gray 12AM to the days of the month.

And also change the color of this gray including MouseOver.

 

A while back, I was looking to implement a pan feature for my ChartView3D, Telerik directed me to this feature request.  It says you aren't implementing the feature but it does contain sample code to allow me to manually pan the view myself.  I have attached a copy of the sample to this post.

It all mostly works. but I've noticed that the horizontal panning is not true horizontal panning.  If you hit the left or right arrow button just a few times sure it looks that way.  But as you keep moving it left or right and the chart approaches the edge of the windows, it begins to move downward also, as if it were the edge of a large, rotating wheel.

What I need is true XY panning. So that if I hit the left button the scene moves left ONLY, not up or down, no matter how far I move it.

Is there some way to adjust the code in the sample to achieve this?  I'll admit that this sort of math is not at all my strong suit.
