Hi,

How to get the cellborder focus rectangle (see attached) in the Telerik.Windows.Controls.RadSpreadsheet.ActiveWorksheet?

I tried this but this doesn't give the desired output:

View.sprSpecification.ActiveWorksheet
.Cells[rowIndex, colIndex]
.SetBorders(new CellBorders(new CellBorder(CellBorderStyle.Thin, ThemableColor.FromArgb(alfa: 255, red: 255, green: 0, blue: 0))));

I'm using Telerik 2017.2.614.45.NoXaml

Thanks,

Sri

Dear Telerik Team,

I have problem how to change label and get list of legend in chart WPF. For detail Question please see the attached file.

Tq.

Hello, I found a weird behavior with the trackball display when the chart is a bit large. Right now I'm displaying some statistics for a year worth of data, which demands a user scroll. I'm not using the Pan and Zoom as it adds complexity to the experience with the chart, so I'm just expanding the RadCartesianChart Width until it display all the data that I need to show, like this:

The problem is that, when I'm displaying the TrackBallInfoControl, and the Width of the Chart is higher than 15000 px, the Trackball control stops to move with the mouse and gets stuck at the 15000 px mark. The TrackBallLines are working fine, the problem only happens with the modal (tooltip) that is displayed.

The problem seems to be in the ChartTrackBallBehavior.

Why do you have such restriction, and how can I overcome it? Are there any workarounds for the RadCartesianChart and TrackBallInfoControl to make it work without facing this problem?

Thanks in advance

I am developing an application and I used LayoutControl , I noticed that the window persist in memory when I close it  , even if I use GC.Collect() to wake up garbage collector, there is a memory leaks concerning LayoutControl.  

Otherwise, if I put any other telerik component like RadGridView or RadMenu the window object is removed from the memory after closing .

Please help because I use  LayoutControl in 120 interfaces.

I use ANTS Memory Profiler 8 , Telerik UI for WPF R3 2017 SP1 , win7 sp1 x64 , visual studio 2013.

Hello

I need change some PropertyDefinition's IsEnabled on run time,my solution is change PropertyDefinition's IsReadonly
public virtual void SetEnabled() 
{
            var squidProperties = this.FindChildByType<RadPropertyGrid>() as RadPropertyGrid;
            if (squidProperties == null)
                return;
            foreach (var item in squidProperties.PropertyDefinitions)
            {
                item.IsReadOnly = !_enable;
                if (item.HasNestedProperties) 
                {
                    foreach (var subItem in item.NestedProperties) 
                    {
                        subItem.IsReadOnly = !_enable;
                    }
                }
            }
  }

when the PropertyDefinition has  EditorTemplate, when  the EditorTemplate is single control  as the following code  it is works right

<telerik:PropertyDefinition.EditorTemplate>
              <DataTemplate>    
                         <telerik:RadWatermarkTextBox 
                                                             IsReadOnly="{Binding IsReadOnly, RelativeSource={RelativeSource AncestorType=telerik:PropertyGridField}}"
                                                             Text="{Binding Filter}" />                                
                 </DataTemplate>
</telerik:PropertyDefinition.EditorTemplate>

but  when the EditorTemplate is nested controls  as the following code,  it is works wrong

   <telerik:PropertyDefinition.EditorTemplate>
                        <DataTemplate>
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="*" />
                                    <ColumnDefinition Width="auto" />
                                </Grid.ColumnDefinitions>
                                <telerik:RadWatermarkTextBox Grid.Column="0"
                                                             IsReadOnly="{Binding IsReadOnly, RelativeSource={RelativeSource AncestorType=telerik:PropertyGridField}}"
                                                             Text="{Binding Filter}" />
                                <telerik:RadButton  />
                            </Grid>
                        </DataTemplate>
</telerik:PropertyDefinition.EditorTemplate>

the RadWatermarkTextBox status is not readonly, when set the PropertyDefinition isreadonly true 

what is the reason for this?
