Same as WPF feature request

Same as in WPF

Spellchecking specific text throws NullReferenceException. Specific example would be '..)aaa' text.

please add persian culture "fa-IR' to RadCalendar 
with thanks

In the Office2013 theme for both SIlverlight and WPF in the latest version, the RadTabItemStyle has the Office Black for unfocussed tabs.

To fix this I added the lines:

        <Setter Property="Background" Value="{x:Null}" />
        <Setter Property="BorderBrush" Value="{x:Null}" />

Not sure if that is the right place to fix it, because in the previous version of the Office2013 theme (where the RadTabItem had the right style) those 2 lines were not present.
==========================
DECLINED DUE TO INACTIVITY.

Since the Q12015 update, if you add a RadCalendar to a project, and try to use the No XAML binaries with the VisualStudio2013 or Office2013 themes, the designer will crash. 
Sample project attached.

Hi Guys,

We have a pretty large app that relies on many of your components. We have become aware of Memory leaks in our products that over time crash the application. Every time we try to track down where they are coming from it always ends up being in the unmannaged memory that ties to your objects. 

One of the problems we have is with the Telerik RadGridView. We store a lot of data into these grid views and when the user clears the data in the grid views we expect the memory to be free'd up and not to keep stacking.

I went ahead and made a sample application to show you guys. All I'm doing is adding rows to the grid via a ObservalbleCollection<string> bound to the ItemSource and then clearing that ObservableCollection. When we clear we expect it to clear from memory. I even included GC.Collect() and GC.WaitForPendingFinalizers in the clear function for testing. No matter how many times I call the clear button the memory stays put. 

 I noticed if we turn autogeneratecolumns on it will then start clearing the memory over time but if we have it off it will never clear the memory I'm not sure why this is.

1.Open the sample eapplication (Attached).
2.Open Task Manager to View Memory Usage by Process.
3.Continuously add rows to the grid by clicking the add button.
4.Notice how the memory continuously goes up for the IExplore process tied to this program.
5.Click the clear button.
6.Notice how the memory never goes back down for that process.
7.No matter how long you wait or how many times you click the clear button the memory stays.


Thanks,
David Pinho

Open the ColorPicker

Then add Color in the RecentColorsitemsSource collection. Open the Colorpicker again - recent colors are not visible.


Available in LIB version: 2014.3.1124

Annotations are not positioned correctly, when the vertical scrollbar is visible.

The fix is available in LIB Version 2014.3.1319.

Problem noticeable by observing growth in queued changes to be processed. 

it would be cool if your controls can be used in Xamarin

Now, the only supported charts for the integration between RadPivotGrid and RadChartView are Bar, Area and Line. hope also support like pie chart ...

When the VisualizationLayer.ShapeFill property uses the StrokeDashArray then the System.Reflection.TargetInvocationException exception ("The value does not fall within the expected range") is thrown.

Available in Q3 2014.

Hello,

I have a problem with the RadMap component which leads the silverlight plugin to a crash.
Basically i'm changing periodically the center of the map using the "ZoomLevel" and the "Center" properties of the map and after a casual number of times the silverlight plugin crashes with an  "AccessViolationException"

In order to reproduce the issue is sufficient to create a project with a simple user control with the following XAML:

<UserControl x:Class="RadMapTest.Map"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">
     
    <Grid x:Name="LayoutRoot" Background="White">
        <telerik:RadMap x:Name="MapControl" >
            <telerik:RadMap.Provider>
                <telerik:ArcGisMapProvider Mode="Aerial"  />
            </telerik:RadMap.Provider>
        </telerik:RadMap>
    </Grid>
</UserControl>


And the following code behind:

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Threading;
 
namespace RadMapTest
{
    public partial class Map : UserControl
    {
        private bool zoomOut;
        private DispatcherTimer timer;
        private Random random;
 
        public Map()
        {
            this.zoomOut = true;
            this.timer = new DispatcherTimer();
            this.random = new Random(DateTime.Now.Second);
            InitializeComponent();
 
            this.Loaded += OnLoaded;
        }
 
        private void OnLoaded(object sender, RoutedEventArgs e)
        {
            this.timer.Interval = TimeSpan.FromMilliseconds(1000);
            this.timer.Tick += this.OnTick;
            this.timer.Start();
        }
 
        private void OnTick(object sender, EventArgs e)
        {
            this.MapControl.Center = new Telerik.Windows.Controls.Map.Location((random.NextDouble() * 180) - 90, (random.NextDouble() * 360) - 180);
            this.MapControl.ZoomLevel = zoomOut ? this.MapControl.MinZoomLevel : random.Next(this.MapControl.MinZoomLevel, this.MapControl.MaxZoomLevel);
 
            zoomOut = !zoomOut;
        }
    }
}

I was able to reproduce this issue with the Silverlight Q1 2014 and Silverlight Q2 2014.
Also I have tried both Bing and ArcGIS providers.

In the test i'm using a very short animation time (1 sec), but the problems persists also with longer timings (e.g. 45 sec).

Can you provide some help on this?

Counting distinct items is often necessary in a grid.  Showing the number of customers in a list of orders for example (one customer may have multiple orders listed in the Grid).

With 2016 Q1 version, a static TouchManager class was introduced allowing for handling touch gestures and defining custom gestures.

If you are using PopupExtensions for Silverlight to set Placement of the Popup and you zoom your browser, the Popup will not be on the correct position if the element in which you've defined the Popup has Margin set.
