Hi,

I made a table using RadGridView and in one of my columns I wanna have another XAML element insted of having text.
I have columns like this one : 

<telerik:GridViewDataColumn UniqueName="NameColumn"
                                                x:Name="NameColumn"
                                                Width="*" 
                                                TextAlignment="Left"
                                                Header="{Resx Common_Label}"
                                                MinWidth="200"
                                                DataMemberBinding="{Binding TankName}"
                                                IsFilterable="False">
                    <telerik:GridViewColumn.CellStyle>
                        <Style TargetType="telerik:GridViewCell">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate>
                                        <Border BorderBrush="LightBlue" BorderThickness="0 0 1 0">
                                            <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Center" TextAlignment="Left" Margin="20, 0, 0, 0" Text="{Binding TankName}" FontFamily="Segoe UI" FontSize="16" />

                                </Setter.Value>
                            </Setter>
                        </Style>
                    </telerik:GridViewColumn.CellStyle>

Hello,

We are experiencing an issue with ArcGIS maps not displaying in the RadMap in our software, instead, all that is seen is a grey screen. 

We have made no changes to the code and have not issued a new release for some time so are struggling to understand why this failure is occurring. 

Also, strangely, in the debug environment the issue does not exist, only in the compiled and released version.

Can any guidance be given to help us understand and fix this problem?  Has something changed in the interface between the Telerik control and ESRI that we need to account for?

Thanks,

Rich

I have a radpane include a context menu. when right click over context menu, Radpane is closing and it'is problem for this component.
I used contextmenuopening event but it works before closing and it is not good idea

code is below:

<telerik:RadPaneGroup  Margin="0,0,0,0" >
                    <telerik:RadPane  Name="PaneProcess" CanUserClose="False" >
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="24" />
                                <RowDefinition Height="*" />
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="*" />
                            </Grid.ColumnDefinitions>
                            <telerik:RadWatermarkTextBox x:Name="FilterTree" Grid.Column="0" Grid.Row="0" BorderThickness="1"
					 Margin="0,0,0,0"
					 VerticalAlignment="Top" 
					 MinHeight="24" />
                            <c:TreeViewProcess x:Name="treeViewProcess" IsDragDropEnabled="True" Grid.Row="1" />
                        </Grid>
                    </telerik:RadPane>
                </telerik:RadPaneGroup>

Hi, I wanted to know if it's possible to change the color of tasks in the colum area. In my case, I need to put colum background on blue if the task has a children. I put an example below of how I want to be the result. 

I have  a ScheduleView .xaml like this:

<Window>

...

    <Grid>
        <telerik:RadScheduleView  AppointmentsSource="{Binding Appointments}"
            <telerik:RadScheduleView.ViewDefinitions>
                <telerik:DayViewDefinition/>
                <telerik:WeekViewDefinition/>
                <telerik:MonthViewDefinition/>
            </telerik:RadScheduleView.ViewDefinitions>
        </telerik:RadScheduleView>
    </Grid>
</Window>

And every time I open the window, my ViewModel is loading the Appointments like this:

Appointments = new ObservableCollection<Appointment>();

    private async Task CreateAppointments()
    {
         Appointments = await _service.GetAllAppointments();
    }

While the _service retrieves the data from the server only once and saves it to memory as an ObservableCollection, and next time brings it just from memory.

The first time I opened the Schedule window, everything is working well.

But the next time I opened the Schedule window, I can see that the Week-view and the Day-view are looking the same. if I am trying to press the Day or Week buttons the view is jumping forth and back and stayed the same. (see pictures attached).

I notice that if I'm just changing my code to be like this: (no other changes)

 private async Task CreateAppointments()
    {
         Appointments.AddRange(await _service.GetAllAppointments());
    }

It makes the issue disappear and all is working well.

But I don't want to use AddRange because I need my UI to be bounded directly to the ObservableCollection from the _service so I can be notified on any collection changed by the _service side.

[update:]

After this, I found that if I set Appointments to null on the window close, all back to work well (without the need to use AddRange),

I just added to the code behind like this:

private void ScheduleWindowView_OnClosed(object sender, WindowClosedEventArgs e)
        {
            (DataContext as IDisposable)?.Dispose();
        }

And I also added to my ViewModel  this implementation:

I can live with this solution, but can anyone explain what exactly was the issue and how it was solved?

I am trying to achieve customized slider control required customizations are :

1.Thumb with the teal color

2.Repeat buttons end with rounded corners

3.Inside tick bar ticks as circles or ellipse instead of lines(please refer attached image.png file blue arrow mark)

 I am able achieve first and second points above, but third point I am not getting.

Hi,

Would it be possible to have a editable RadComboBox TextBox Part to mimic the RadWatermarkTextBox with floating Label?
