Removing header

Hi there,

I'm trying to host a RadTimeLine inside a RadTimeBar so that I can view timeline events but with the selection ability of the TimeBar.

a) If I want the mouse scrolling to work, I need to have intervals set on my RadTimeBar, but I don't want duplicate intervals to be displayed. I can't seem to make the header height for the RadTimeLine drop to zero - is it possible to completely hide either of the headers?

b) I'd like the cursor to just be a single line rather than a selected range - representing an instant in time rather than a period. Is there a simple way to do this?

Many thanks

Nick

Docking with single RadPaneGroup within DocumetnHost

Hi,

Is it possible to limit the number of RandPaneGroup within a RadDocking control?

At this moment, we have one RadSplitContainer with RadPane in it on the left for navigation purpose.

And another DocumentHost with one RadPane in it occupying the rest of area.

When there are multiple RadnPane in the RandPaneGroup of the DocumentHost, they can be draaged out to float, and when they dock back, we would like to make the float window docked back to the original PanGroup they are from.

The reason is we are using Prism region with radDocking. When they radpane are docked back to diffrent RadPanGroup. exceptions will be thrown.

Is it possible to do it? Does it need to disalbe some indicator of the Compass?

Regards,

Yu

Databinding RadMap Center and ZoomLevel

I have data bound the RadMap Center and ZoomLevel to properties in my ViewModel. These work fine up until I move the map or zoom in/out using the mouse. It appears as if the databinding is no longer working. I'm firing the OnPropertyChanged events but the map fails to respond. The mouse events are being handled directly by the control.

Any Idea if this is a bug? Or should I update these properties in another way?

[Solved] Unit testing VirtualQueryableCollectionView

Is it possible to write unit test against the VirtualQueryableCollectionView? I tried to write a unit test to verify the VirtualItemCount, but it seems that the collection is tightly coupled to the UI components and therefore requires tests to run on a STA thread. Is this correct?

AggregateFunctions and GridViewDataColumn Footer Issue

Hi,

I am trying to use the AggregateFunctions and display them inside the Footer of the Grid using ItemsControl.ItemTemplate similar to the sample you provide. Though this works fine I have run into a problem, I have a tab control with 2 tabs inside each tab I have a Grid both using AggregateFunctions displayed in the footer using the ItemsControl.ItemTemplate. Initially the footers are displayed fine, if I however move between tabs/grids the footers are displayed empty.

If I do not use the ItemsControl.ItemTemplate approach the footers work fine, if I go and add or update the contents of the grid then the footer is displayed correctly again.

This code does not work:

    
            <telerik:GridViewDataColumn Header="Available Amount" UniqueName="Amount" DataMemberBinding="{Binding Amount}" > 
        
                <telerik:GridViewDataColumn.AggregateFunctions> 
        
                    <telerik:SumFunction Caption="Sum: " ResultFormatString="{}{0:0}" SourceField="Amount" /> 
        
                    <telerik:AverageFunction Caption="Average: " ResultFormatString="{}{0:0}" SourceField="Amount" /> 
        
                </telerik:GridViewDataColumn.AggregateFunctions> 
        
                <telerik:GridViewDataColumn.Footer> 
        
                    <StackPanel Orientation="Vertical" Margin="5,0">  
        
                        <telerik:AggregateResultsList ItemsSource="{Binding}" VerticalAlignment="Center" Grid.Column="4">  
        
                            <ItemsControl.ItemTemplate> 
        
                                <DataTemplate> 
        
                                    <StackPanel Orientation="Horizontal" VerticalAlignment="Center">  
        
                                        <TextBlock VerticalAlignment="Center" Text="{Binding Caption}" Width="100"/>  
        
                                        <TextBlock VerticalAlignment="Center" Foreground="Blue" Text="{Binding FormattedValue}" /> 
        
                                    </StackPanel> 
        
                                </DataTemplate> 
        
                            </ItemsControl.ItemTemplate> 
        
                            <ItemsControl.ItemsPanel> 
        
                                <ItemsPanelTemplate> 
        
                                    <StackPanel Orientation="Vertical" /> 
        
                                </ItemsPanelTemplate> 
        
                            </ItemsControl.ItemsPanel> 
        
                        </telerik:AggregateResultsList> 
        
                    </StackPanel> 
        
                </telerik:GridViewDataColumn.Footer> 
        
            </telerik:GridViewDataColumn>

This code does display but I would really like to control how it is displayed:

    
            <telerik:GridViewDataColumn Header="Available Amount" UniqueName="Amount" DataMemberBinding="{Binding Amount}" > 
        
                <telerik:GridViewDataColumn.AggregateFunctions> 
        
                    <telerik:SumFunction Caption="Sum: " ResultFormatString="{}{0:0}" SourceField="Amount" /> 
        
                    <telerik:AverageFunction Caption="Average: " ResultFormatString="{}{0:0}" SourceField="Amount" /> 
        
                </telerik:GridViewDataColumn.AggregateFunctions> 
        
            </telerik:GridViewDataColumn>

I am using Q2 2009 (Version: 2009.2.701.35)

Hopefully it is something I am missing.

Regards,
Glen

[Solved] SettingsPane.Editor using ListBox

Good Day,

We use Telerik WPF controls Version 2012 Q2. we have a problem regarding the handling of the menu of options offered by the RadDiagram, modify the content and include new options. The problem is that we want to load a list of options through the DependencyProperties, this was possible but we can not tell you to select element after being added as the method telerik: SettingsPaneView.EditorValue being used to tell the ListBox to property friendly.

Down with information on how we are achieving this. hope can help,
Thank Telerik Team.

ListColumn = List different values
ListColumnSelectedItem = Selected Item

telerik:SettingsPaneView.EditorPropertyName="ListColumn" <telerik:RadListBox telerik:SettingsPaneView.EditorItemType="Shapes,Custom" telerik:SettingsPaneView.EditorValue="{Binding ItemsSource, Mode=TwoWay, RelativeSource={RelativeSource Self}}">
</ telerik: RadListBox>

[Solved] slowness tabbing between cells

I have a RadGridView and DataGrid implementation of a grid with with about 20 columns. A large number of the columns use cell templates and some of them use converters as well. I've noticed that when I edit and then tab between columns the RadGrid's performance has a noticeable lag compared to the DataGrid. Any ideas as to what might cause this and ways to alleviate?

Thanks,
Alex
