Good day.

Does RadPasswordBox support Chinese characters?
We have problems with entering Chinese characters in RadPasswordBox.
1. The entered data is not hidden.
2. The show button will disappear.
3. Password values are not assigned.
4. The entered data cannot be deleted.

Below is a link to the project and files.

Multiple 2D spline area series in 3D

I would like to see data from multiple 2D graphs in the same 3D chart. Is this possible to do?

For example show a ScatterSplineAreaSeries in the XZ plane at Y=0 and show a separate spline series in the XZ plane at Y = 1.

I was hoping I could use a SurfaceSeries3D to accomplish this but I could not figure out how to feed it points that accomplished the same spline effect as in the 2D RadChartView.

exports only the records shown in grid using GridViewSpreadStreamExport

Hi

I'm trying to export ALL the records using GridViewSpreadStreamExport. Here is the snippet.

But the excel sheet is only showing the records displayed in the grid (which is 20). I have a RadDataPager and the is set to 20 with source ElementName as RadGridView.

How do I export all data in the Logs ItemSource of the grid?

<telerik:RadGridView x:Name="rgvLogs"

IsBusy= "{Binding IsBusy}"

ItemsSource="{Binding Logs}"

AutoGenerateColumns="True"

IsReadOnly="True"

ShowColumnSortIndexes="True"

CanUserDeleteRows="False"

CanUserInsertRows="False"

CanUserSortColumns="True"

CanUserFreezeColumns="False"

GroupRenderMode="Flat"

Grid.Row="1">

</telerik:RadGridView>

<telerik:RadDataPager x:Name="radDataPager"

PageSize="20"

IsTotalItemCountFixed="True"

DisplayMode="All"

Grid.Row="2"

FontSize="12"

AutoEllipsisMode="Both"

NumericButtonCount="10"

Source="{Binding Items, ElementName=rgvLogs}"/>

01.private void AsyncExport(object param)

02. {

03. string extension = "xlsx";

04. var rgvExportToExcel = param as RadGridView;

05.

06. var dialog = new SaveFileDialog()

07. {

08. DefaultExt = extension,

09. Filter = String.Format("(*.{0})|*.{1}", extension, extension),

10. FilterIndex = 1,

11. AddExtension = true,

12. Title = "Export to Excel",

13. };

14.

15. if (dialog.ShowDialog() == DialogResult.OK)

16. {

17. GridViewSpreadStreamExport spreadStreamXlsxExport = new GridViewSpreadStreamExport(rgvExportToExcel);

18. spreadStreamXlsxExport.ShowLoadingIndicatorWhileAsyncExport = this.ShowLoadingIndicatorWhileAsyncExport;

19. spreadStreamXlsxExport.RunExportAsync(dialog.FileName.ToString(), new SpreadStreamExportRenderer(),

20. new GridViewSpreadStreamExportOptions()

21. {

22. ShowColumnHeaders = true,

23. ShowColumnFooters = true,

24. ExportDefaultStyles = true

25. });

26. }

27.

28. }

Diagram via NuGet

Hello,

I'm referencing Telerik UI for WPF assemblies via NuGet which works fine. But when I tried to use RadDiagram in a simple project the Diagram does not display at all using the references from NuGet.

If I remove the NuGet packages in the project and add all necessary references from local disk the diagramm displays as expected. If I switch back to NuGet it does not work again.

Is there something I made wrong?

<telerik:RadDiagram>

<telerik:RadDiagramShape x:Name="Shape1"

Content="Shape 1"

Position="80,20" />

<telerik:RadDiagramShape x:Name="Shape2"

Content="Shape 2"

Position="320,20" />

</telerik:RadDiagram>

GridView row reorder by drag and drop issue

Hi,

I use GridView and I wanted to add drag and drop row reorder functionality so I implemented it with RowReorderBehavior based on your examples.

But it doesn't work well, sometimes some row (for example first row) does not respons to drag and drop, but it works well for the rest of the rows.

Any suggestions?

Thank you!

Can the CurrentTimeIndicator respect differences in Time Zone?

I have a RadScheduleView that may be representing appointments in the local time of a different time zone. I set the TimeZone and TimeZonesSource of the RadScheduleView to the TZ of where the appointment is taking place, but the CurrentTimeIndicator always reflects the local time instead. Is there any way for the CurrentTimeIndicator to reflect the time from a different time zone?

Customize Group Header Indicator and Group Row Indicator

I have an application where I do grouping behind the scenes with an ICollectionView. I have the group panel and row indicator hidden. When I do using the ICollectionView, I get a row indicator in the header and for each row. I'd like to change the border color of the header indicator space to transparent and the row indicator to match the background of the main grid. I've looked around the different templates and can't figure out which is the right one.

TreeView UI issue

Hi -
I am seeing strange gaps between folders within different nodes (screenshot is attached).
issue is no reproducible on all devices I run the app.
I thought it might be related to the default animation when root folder is expanded, but I disabled it and still seeing same issue.
Any thoughts why this is happening would be appreciated.

Thanks,
Ranko
