[Solved] Support for .NET 4.5 BindingOperations.EnableCollectionSynchronization

With .NET 4.5 there is the new BindingOperations.EnableCollectionSynchronization feature that would enable support for updating a ObservableCollection in the background thread, thus removing the need to dispatch to UI thread every time.

However, the current RadGridView doesn't seems to be happy with it, the first item appears fine, but then it throws the usual "wrong thread" exception for the second item.

When will the new BindingOperations.EnableCollectionSynchronization be supported in the Telerik items controls?

Chinese characters in RadPasswordBox

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. }
