When you resize (but only decreasing size) the control, the position and size of the Marker indicator is not updated.
This is reproducible with RadVerticalLinearGauge and VerticalLinearScale. When the RelativeHeight of the scale is set to 1 and the RelativeY is set to 0.As a work around you can avoid setting the RelativeHeight and RelativeY properties of VerticalLinearScale.
Users reported that the Text Search feature is misbehaving for certain columns in their grid.
We found that that if we take the Telerik example “DeferredSearching_WPF.sln", and change the "int" field+property to "long" , text search for a number indeed falls over.
Can you reproduce this?
Kind regards, Bertus Distributie ICT
RadPdfViewer does not read image resources defined in Form XObject elements.
If a document contains many and complex formulas (with many functions having other functions as arguments) it may take a long time to show in the control.
When Depth property is set it is expected that the undo stack would not keep more items than the depth value. However, this behaviour is not working in ImageHistory class and could lead to OutOfMemoryException when the stack gets full of ImageHistoryItem instances. Steps to reproduce: 1. Open ImageEditor and load some image. 2. Set ImageEditor.History.Depth = 1. 3. Make a few rotations. Expected: When making Undo you should be able to undo only the last rotation. Actual: You can Undo all the rotations meaning that Depth property is not respected.
Environment: VS Community 2019 (16.0.3), with .NET Framework 4.8 (release version, run-time and developer pack installed), Windows 10 Pro October 2018
Telerik UI version: latest (2019.1.220.45)
When VS2019 opened, Telerik UI for WPF should have been found under the "Extension" menu --> Telerik --> Telerik UI for WPF. However, there is only "Telerik UI for WinForms" under "Telerik" now. There is neither "Telerik scenario" in the "Add New Item" window so no RadForms can be created. Manually replacing <Window> in XAML to <telerik:RadWindow> does change the appearance of the window in the designer, but the properties in the Property window does not change accordingly to RadForms but still WPF standard Form ones. Toolboxes shows current lists of Telerik UI for WPF controls and they can be correctly created (at least RadButton). "Repair" in the Progress Control Panel doesn't fix this problem.
The following exception is observed in certain cases:
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RealizeMergedCells(Double frozenOffset, IEnumerable`1 mergedCells)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.CalculateMergedCells(Boolean shouldInvalidateMeasure)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.CalculateMergedCells(Boolean shouldInvalidateMeasure)
at Telerik.Windows.Controls.GridView.GridViewCellsPanel.ArrangeOverride(Size finalSize)
Currently when you highlight a row in the child GridView, the ParentRow becomes highlighted. It would be really nice to have an option so that the ParentRow would be selected when a row in the child GridView is selected. This should work recursively selecting the ParentRow all the way up the hierarchy.
I've written a workaround, but it isn't pretty.
Please add this functionality. :)
My case involves a three tier hierarchical GridView (each in single select mode). If I select a row in a third tier GridView, then I want its ParentRow to become selected on the second tier and the second tier's ParentRow to become selected on the first tier. Hopefully that makes sense.
The exception is thrown for the RotationAngle property.
The issue can be observed also in the opposite direction - the diagram is serialized on a machine with some culture (for example Portugal Porguese - pt-PT) and then restored on a machine with an English culture.
The issue reproduces only when saving and loading between cultures which numeric separators are different. For example, with Bulgarian culture, the number 4.5 is represented as 4,5 (with a comma). With English culture the number will be represented as 4.5 (with a period).
To work this around, create a custom RadDiagramShape and override its Deserialize() method. Then parse the RotationAngle manually, and set it to the RotationAngle property of the shape. After this, set the RotationAngle of the SerializationInfo to null, in order to prevent the default restoring of the property.
Here maps has the ability to render map tiles with traffic. They include a freemium tier unlike some of the others.
I've created buttons that are bound to FileDialogCommands for sending commands to an ExplorerControl, as shown here:
Everything works when the ExplorerControl is visible. However, if the ExplorerControl's Visibility is set to Collapsed (which I need based on a condition), the Command bindings on the buttons throw the below error:
System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.Windows.Controls.FileDialogs.ExplorerControl.CanExecuteHelper(Object sender)
The UserControl that hosts the ExplorerControl is being imported through MEF. I don't know if that's a factor.
Either way, it looks like a null check might be needed for the InternalViewModel property.
A useful new control would be : RadWebcam It would show webcam view in realtime and call a function each x seconds (or ms), would be useful for : - user picture to attach to its user account - quick product picture - and for my need : call an external function for barcode recognization I think it would be easy and fast to create this control for WPF, and it would fit perfectly with Silverlight 4 (or 5 ?) webcam support.
In that way it will be easily modified through the palette of themes such as Windows8, Windows8Touch, Office2013 and VisualStudio2013 and it won't be needed to overwrite the whole template. That feature is very important for users with visual impairment or where low contrast screens are used.
