VS2017 - Object does not match target type

XAML editor complains “Object does not match target type” while using the RibbonView. I have the latest updated VS2017.

I have tried using the threads on StackOverflow.

https://stackoverflow.com/questions/14591781/object-does-not-match-target-type

https://stackoverflow.com/questions/31815177/design-mode-error-object-does-not-match-target-type-for-loaded-page-resource

https://stackoverflow.com/questions/31726759/xaml-editor-complains-object-does-not-match-target-type-for-sharedresourcedict

I was not able to resolve my error using them links. The source compiles and runs but the editor complains and it is irritating and obstructing actual errors.

Thanks in advance :)

RadDiagram custom shape connector target problem

Hi,

I have created a custom shape and when i use the shape as a connection target, the connection does not bound to my shape. In other words the shape color does not change (as a RadDiagramShape does when mouse goes over it) when I try to choose the shape as a connector target. Also "e.Connection.Target" in ConnectionManipulationCompleted event is null.

It works correctly as a connection source.

Is there any setting for my custom shape?

Thanks.

Bing imagery sets

I'm using an older version. Do the new versions have built-in support for the new (?) imagerySet values? If not, how would I add them? I've used my own or inherited versions of OSM classes, but the Bing classes are more complex and have more levels of inheritance. Below is the documentation for the static map, but I don't know if this applies to Tiles, too.

https://msdn.microsoft.com/en-us/library/ff701724.aspx

Aerial – Aerial imagery.
AerialWithLabels –Aerial imagery with a road overlay.
CanvasDark - A dark version of the road maps.
CanvasLight - A lighter version of the road maps which also has some of the details such as hill shading disabled.
CanvasGray - A grayscale version of the road maps.
Road – Roads without additional imagery.

Export to xlsx format issues

I am using GridView's export functionality of 2016.1.217.45 version, see below the code snippet.

string extension = "xls";

SaveFileDialog dialog = new SaveFileDialog()

{

DefaultExt = extension,

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

FilterIndex = 1

};

if (dialog.ShowDialog() == true)

{

using (Stream stream = dialog.OpenFile())

{

m_oGridView.Export(stream,

new GridViewExportOptions()

{

Format = ExportFormat.Xlsx,

ShowColumnHeaders = true,

ShowColumnFooters = false,

ShowGroupFooters = false,

});

}

Following are the issues observed, please provide solutions or workarounds:

The first row in the grid is not getting exported as second row in excel, instead it is appearing in the first row of excel after the row headers. See the snapshots - "GridUISnapshot.JPG" and "ExcelSnapshot.JPG".
If the users specifies the extension of the file as ".xlsx", it is getting exported but not able to open in excel 2016 version, the error message is shown in the snapshot - "XlsxExtensionOpenError.JPG". Since in File save dialog, user can specify .xlsx extension as well. In code we are specifying the format to be exported is xlsx, but still it is not compatible.

Thanks,

Viksit

Search Panel and Combo Box Column

I'm playing around with the developer example projects for the gridview, specifically the "ComboboxColumnItemsSourceBinding", and I enabled the Search Panel on the Gridview where FilterMemberPath is set, but noticed it doesn't search inside the ComboBox Column. If I type for "Webber" in the Search Panel it comes up with nothing.....but the filter control for that column will work.

Is there something I am missing in the demo that I need to add to get this functionality working? Or do I need to go as far as making my own predicate and use FilterDescriptor<T>?
