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.

Hi,

in my application we have an ui which displays transaction data in it's raw form (XML Data), it's optional exception and a further content control with some parsed datails.

The structure of the RadWindow the following:

<UserControl x:Class="TransactionXmlDataView"
             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">

    <telerik:RadBusyIndicator x:Name="BusyIndicator">
        <Grid HorizontalAlignment="Stretch"
              Height="Auto"
              Width="Auto">

            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="Auto" />
                <RowDefinition Height="1*" />
            </Grid.RowDefinitions>

            <ContentControl x:Name="ParsedTransactionDataViewer"
                            Visibility="{Binding HasParsedTransactionData, Converter={StaticResource BoolToVisibilityConverter}}" />

            <TextBlock Text="{Binding DisplayName}"
                       HorizontalAlignment="Left"
                       Grid.Row="1"/>


            <telerik:RadLayoutControl Grid.Row="2">
                <ContentControl x:Name="XmlDocumentFileViewer" Width="{Binding XmlViewerWidth}"/>
                <telerik:LayoutControlSplitter Visibility="{Binding ExceptionViewerVisible, Converter={StaticResource BooleanToVisibleCollapsedConverter}}"/>
                <TextBox x:Name="ExceptionText"
                         TextWrapping="Wrap"
                         IsReadOnly="True"
                         VerticalContentAlignment="Top"
                         Visibility="{Binding ExceptionViewerVisible, Converter={StaticResource BooleanToVisibleCollapsedConverter}}"/>
            </telerik:RadLayoutControl>
        </Grid>
    </telerik:RadBusyIndicator>
</UserControl>

Not all parts of the UI are always shown:

• The ParsedTransactionDataViewer is optionally shown in the first row of the grid. The whole row is collapsed if there is nothing to show
• The LayoutControlSplitter and the Textbox "ExceptionText" within the third row are optionally shown. When there is no Excpetion to show the Splitter and Textbox shall be collapsed

Only the ContentControl XmlDocumentFileViewer is always displayed. This ContentControl is a UserControl with another ContenControl inside which Content is Binding to an RadSyntaxEditor in the Code.

<UserControl x:Class="XmlDocumentFileViewerView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ContentControl Width="Auto"
                    Height="{Binding ContentHeight}"
                    Content="{Binding XmlRadSyntaxEditor}" />
</UserControl>

<UserControl x:Class="TransactionXmlDataView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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

    <telerik:RadBusyIndicator x:Name="BusyIndicator"
                              Style="{DynamicResource InputRadBusyIndicatorStyle}">
        <Grid HorizontalAlignment="Stretch"
              Margin="10"
              Height="Auto"
              Width="Auto">

            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="Auto" />
                <RowDefinition Height="1*" />
            </Grid.RowDefinitions>

            <ContentControl x:Name="XmlDocumentFileViewer" Width="1000" Height="1000"/>

        </Grid>
    </telerik:RadBusyIndicator>
</UserControl>

<UserControl x:Class="XmlDocumentFileViewerView"

        HorizontalScrollBarVisibility="Visible"
