Adding bookmarks with the same name programmatically always returns the first one in case use attempts to navigate to it using the Bookmarks dialog.
Workaround: Remove the bookmark before adding a new one with the very same name.
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.
We have a RadRibbonWindow. When it is run on Windows XP (or on Windows 7, "Windows Classic" theme) and the DPI settings are high (above 170 %), the standard window buttons (Minimize, Restore and Close) are not displayed properly (they are cut). Also there is too much space between them.
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.
Thanks!
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)
As a workaround, you can disable the animation of the ToolWindow:
<Style TargetType="telerik:ToolWindow">
<Setter Property="telerik:AnimationManager.IsAnimationEnabled" Value="False" />
</Style>
The above style need to be placed in the resources of the App.xaml in order to take effect on the ToolWindows, since they are displayed in a separated visual tree.
When the window of an application that has a TabControl with Left/Right TabStripPlacement is resized, the measure of the TabStrip is incorrect and the ScrollButtons are in Disabled state. All Tabs should be visible when the window is in its normal state and should be scrollable.
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.
public partial class CustomShape : RadDiagramShape, IEquatable<BaseShape>{ public override void Deserialize(SerializationInfo info) { if (info["RotationAngle"] != null) { var angle = Convert.ToDouble(info["RotationAngle"].ToString(), CultureInfo.InvariantCulture); this.RotationAngle = angle; info["RotationAngle"] = null; } base.Deserialize(info); }}
Hello.
I've created buttons that are bound to FileDialogCommands for sending commands to an ExplorerControl, as shown here:
https://docs.telerik.com/devtools/wpf/controls/radfiledialogs/features/commands
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.
