Hello,

This big can be reproduced in your demo application:

Open the GridView examples
In the available examples, select "Selection and Usability | Row Details"
Select a rowin the grid view
In the external Details Presenter, select Visible: nothing is displayed in the bottom. You have to select another row and then come back to show the details.

Also another problem: if the external details is inside a ContentPresenter (collapsed at the beginning), it can't find the gridview.

To test this, replace your Border with a ContentPresenter.

Overlapping RadPanes

Hi,

I've got a problem with overlapping RadPanes when using RadDocking Root Compass.

The case is that when I'm dragging RadPanes to the one side of the Root Compass, the Rad Panes on the other side gets overlapped by the dragged ones.
Description may not be clear, so here is simple gif showing the problem:

Pane "Inner Pane C" get overlapped, when dragging new panes to the left side of the Root Compass. It works for every side of the Root Compass.

Is there a simple solution for this issue? Ex. modifying the docked Panes width, to fit them all in the RadDocking control? I've searched on this forum and in the documentation, and couldn't find the solution.

Best regards,

Mateusz

RadRichTextBox "invisible" caret

Hello,

Could you, please, help me to make RadRichTextBox's caret visible?

I've tried to use solution with custom CaretFactory from this post... No results, unfortunately

Is it possible to make caret visible?

Here is some code examples of RadRichTextBox usage (my telerik version: 2018.3.911.45):

<telerik:RadRichTextBox x:Name="descriptionRichBox"

Grid.Row="0" Grid.Column="1" Margin="0,2,0,5" MinHeight="70"

BorderThickness="{Binding IsReadOnly, Converter={localConverters:BoolToBorderThicknessConverter}}"

FontSize="{Binding Source={StaticResource MediumNormal}, Path=Size}"

FontFamily="{Binding Source={StaticResource MediumNormal}, Path=Family}"

IsReadOnly="{Binding IsReadOnly}" GotFocus="RichTextBox_GotFocus"

DocumentInheritsDefaultStyleSettings="True" IsSpellCheckingEnabled="False"

/>

<telerik:HtmlDataProvider RichTextBox="{Binding ElementName=descriptionRichBox}"

Html="{Binding EditableObject.Description, Mode=TwoWay}"

/>

<Style TargetType="telerik:Caret">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="telerik:Caret" >

<Grid x:Name="RootElement" >

<ScrollViewer x:Name="ContentElement" BorderThickness="0" Padding="0" />

<Rectangle x:Name="Rectangle" />

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

<Setter Property="HorizontalAlignment" Value="Left" />

<Setter Property="VerticalAlignment" Value="Top" />

<Setter Property="AcceptsReturn" Value="True" />

<Setter Property="CaretBrush" Value="Black"/>

<Setter Property="Padding" Value="0" />

<Setter Property="Foreground" Value="Transparent" />

</Style>

public class DescriptionCaretFactory : ICaretFactory

{

public Caret CreateCaret()

{

return new Caret { Width = 2, MinWidth = 2, Height=5,

IsBlinking = true, IsEnabled = true,

Visibility = System.Windows.Visibility.Visible,

ToolTip = "test caret",

CaretBrush = System.Windows.Media.Brushes.Black, };

}

Best regards,

Ivan.

Print Workbook wihout use of RadSpreadsheet

I have created a Telerik.Windows.Documents.Spreadsheet.Model.Workbook (with a single Worksheet) programmatically. I can export it to Excel no problem.

How can I print it?

I have found the following article: https://docs.telerik.com/devtools/wpf/controls/radspreadsheet/features/ui-printing#How_to_print_RadSpreadsheet

...but this would force me to work with the UI Control, which I don't want to do. Is it possible to print the Worksheet without the use of the UI control. I still want all the printing options, such as setting a header and footer, forcing the first row to be repeated on every page, control over portrait vs. landscape printing, etc.

Is there any way to do this?

Thanks in advance,

Bartek

Request: Bing aerial zooming

There was an old post about this but I've never been able to find it. At high zoom levels (20 and 21), the Aerial mode usually doesn't show images. Other modes show a zoomed-in version of the previous images, including AerialOnDemand. There doesn't seem to be a way not show labels with AerialOnDemand, unfortunately. Can Aerial be changed so that it also shows the zoomed-in previous images?

Bing documentation says: "Note: Some imagery may not be available at all zoom levels for all locations. If imagery is not available at a location, a message is returned in the ErrorDetails collection of the response."

Performance issues when changing sampling threshold

Hi.
I have a program that in some cases need to show 20+ charts, each with 20 000+ data points, and the charts can be manipulated with pan and zoom so that every chart changes simultaneously. It also needs to have dynamic sampling so that the charts are simplified when displaying many points, but show detail when zoomed in. It works fine when panning, all the charts update smoothly. However when I zoom in or out, I need to change the chartdatasource sampling threshold to adjust the detail, and this is very slow. It takes several seconds for the operation to complete and all charts to update. Why does this take so long and is there any way to speed up the operation?

Today-button includes time

When using the Today-button to select todays date, the selected value also includes the current time. Not what I would expect for the DatePicker. We solve it easy at our end, but I thought you might want to now.
