Hi Telerik,
I want to capture the "close" event when the custom scheduler dialog box is closed below (i.e. clicking on the X button), how can I do so?

Thanks, Cheau

        <ControlTemplate x:Key="EditAppointmentTemplate" TargetType="{x:Type telerik:SchedulerDialog}">           

            <Grid VerticalAlignment="Center" Margin="10">

                <Grid.ColumnDefinitions>

                    <ColumnDefinition Width="150"/>

                    <ColumnDefinition/>

                </Grid.ColumnDefinitions>

                <Label Grid.Column="0" Content="Number of Tap Activity" Height="25"/>

                <telerik:RadNumericUpDown Grid.Column="1"  Height="25" Width="50" NumberDecimalDigits="0" ValueFormat="Numeric" HorizontalAlignment="Left"

                                          Value="{Binding Occurrence.Appointment.TapActivityNum, Mode=TwoWay}" />

            </Grid>

        </ControlTemplate>

 

        <Style x:Key="EditAppointmentStyle" TargetType="telerik:SchedulerDialog">

            <Setter Property="Width" Value="250" />

            <Setter Property="Height" Value="100" />

            <Setter Property="IsTabStop" Value="False" />

            <Setter Property="SnapsToDevicePixels" Value="True" />

            <Setter Property="Template" Value="{StaticResource EditAppointmentTemplate}" />

            <Setter Property="HeaderTemplate">

                <Setter.Value>

                    <DataTemplate>

                        <StackPanel Orientation="Horizontal">

                            <TextBlock Text="Number of Tap Activity" />

                        </StackPanel>

                    </DataTemplate>

                </Setter.Value>

            </Setter>

        </Style>

Hello Telerik Team,

Is it possible to keep the floating panes open (i.e. as is) on the screen when the main window that hosts these panes is minimized?
Currently it minimizes all floating panes. Please let me know.

Hello,

I am experiencing some annoying effects with the Radchart (however, I don't know if these effects are normal or not).

My user control contains a total of 5 Radcharts, each of them having between 1 and 3 linear series (the total number is 10 series). I am  using a SampleThreshold = 400. For those charts with more than one series I am using a "nested collections" binding schema (as explained in the online documentation).

Each serie has exactly 2880 points that correspond to one point every 30 seconds for an entire day. I make an async call to an WCF service that returns the data for the series. 

The problem is that the charts render in a pretty annoying way. First only some X axis labels are shown, then the series appear but only a piece of them and with an offset respect to their X axis correct position... and so on until the chart is correctly displayed. I am not showing any label or pointmark aside from the X axis and Y axis labels, and animations are disabled. 

I'd like to know if there is any way to prevent the chart to be "pre-painted" in the screen, so that it would only be shown as it is correctly composed. Is there something like a "loading data screen" or similar? 

I am using April 2011 release. 

Thank you in advance, 

Pablo.

Hello,

Due to the particular needs of our project, we want the user to be able to zoom over the chart's X Axis but without showing any scrollbar. We would do it using the MouseLeftButtonDown and Up belonging to the plot area, calculating the data points and setting a new RangeEnd and RangeStart for the ZoomSettings object. 

However, right now it is only possible to set ZoomSettings to None, Scroll or ScrollAndZoom. Is there any workaround so that zoom can be made (as described above) but hidding the ScrollBar? If so, could you please provide any code sample?

Thank you very much, 

Pablo.

Hi,

I have a problem since I upgrated from version 2010.3.1314.35 to 2011.2.712.40.
In my scenario I have a "special" TimeRulerItemTemplateSelector which displays a progressbar (status for each day).
With version 2010.3.1314.35 the value-binding (Value="{Binding DateTime, Converter={StaticResource GetDateValue}}") works fine, version 2011.2.712.40 fired the following error:

TwoWay- oder OneWayToSource-Bindungen funktionieren nicht mit der schreibgeschützten Eigenschaft "DateTime" vom Typ "Telerik.Windows.Controls.ScheduleView.TimerRulerItemProxy".

my sources:

            <telerik:TimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>
                <DataTemplate>
                    <Grid Height="60">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="20"/>
                            <RowDefinition Height="20"/>
                            <RowDefinition Height="20"/>
                        </Grid.RowDefinitions>
                        <TextBlock Grid.Row="0" Text="{Binding DateTime, Converter={StaticResource GetWeekDay}}"/>
                        <TextBlock Grid.Row="1" Text="{Binding DateTime, Converter={StaticResource GetDateShort}}"/>
                        <StackPanel Grid.Row="2" Orientation="Horizontal" Margin="2,0,0,0">
                            <ProgressBar Width="40" Minimum="0" Maximum="100" Value="{Binding DateTime, Converter={StaticResource GetDateValue}}"/>
                            <TextBlock Text="{Binding DateTime, Converter={StaticResource GetDateValue}}"/>
                            <TextBlock Text="%"/>
                        </StackPanel>
                    </Grid>
                </DataTemplate>
            </telerik:TimeRulerItemTemplateSelector.HorizontalTimelineGroupTemplate>

and the GetDateValue Function:

Public Class GetDateValue
    Implements IValueConverter

    Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert
        If TypeOf value Is DateTime Then
            Dim dt As DateTime = DirectCast(value, DateTime)
            value = 50   'only for demo...
        End If
        Return value

    End Function

    Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
        Throw New NotImplementedException()
    End Function

End Class

with best regards,
Stefan

Hi Telerik,

                    _cliente.Nome.Length :

                    tam;

Hi,
I am working with RadGridView, in MVVM WPF application and I need to validate cell compared to other values in binding collection.
I have a object :


public class MyObject
{ 
    public DateTime DateBegin { get; set;}
    public int Value { get; set;}
}



And if I add a new row in my GridView with existing Date I want to show error message in cell.
I thought to use an ValidationRules in my cell, but i am not sure if i can compared to with others values in binding list.
I found some solution, but isn't MVVM compliant :

Thanks

Hi,

I need to control the "edit mode" state of the insert row. Let say i have 2 Classes A and B with a "1xN link type" between A and B.
I have in the same screen 2 grids. 1 for type A et 1 for type B. When I add a A in grid 1 I want to be abble of adding Bs in grid2 whitout loosing the "edit mode" of grid 1 insert row.

How coul I do that with the code behind ?

Hi,

I am binding the IsChecked property to a property in my ViewModel with the help of ItemContainerStyle.
When I click on the checkbox of a child "Item 2", I get the following result:

- Group A
   Item 1
x Item 2

So Group A is marked as indeterminate correctly.

When I set Item2.IsChecked  = true in my ViewModel, Item2 is marked as checked, but GroupA is marked as unchecked.

Am I doing something wrong? If not, is there a workaround for this?

Best Regards, Matthias
