Space is premium on my TreeListView.  I removed the Row Selector but I still seem to have a column reserved for it.  Is there a way to set that column to zero width or eliminate it all together?

Thanks for your help,

Joel.

Data Templates:

 

Control Configuration:

 When I use this control or the numeric control I can only type 3 digits and 2 are positioned after the decimal, if I keep typing digits it just overwrites the last decimal place.  Initial value is zero, decimal property, version 2015.2.623.45.

Hi,

 I'm using the latest version of Telerik and I created a UserControl which contain a RadImageEditorUI. My UserControl contain a property named "Image" of type "Stream" and I would like to know how I can display it in the editor and I would like to know also how I can take the image in the editor and transform it as a stream?

 

Thank's

Hi, I would like to use RadTreeView to display a flat list, but all items have significant indentation.

I could have used a RadListBox, but since I have the same nodes in a hierarchically TreeView another place in the application, I thought using the same control would be the easiest way to get the same look and functionality (context menu, click etc).

 

My idea was to set the ItemTemplate of the treeview to a normal DataTemplate or a HierarchicalDataTemplate without specifying ItemSource. It works as I want, except that there is an indention of all the items, leaving a lot of space to the left.

I have also tried to set the ExpanderStyle to a style containing a collapse template, but it only seems to affect the indentation of child items.

I would like to find out if there is a good way of applying DTED information on top of the RadMap so that whenever a user clicks on the

Map location the elevation information can be retrieved. Currently it seems to me that the RadMap can read data from shape files only.

Possible to convert DTED to raster base information to be applied on RadMap?

Hi, does the RadDocking control use virtualization? And can I disable it? To be more specific, after a user action, I add a new Pane to a PaneGroup and set its Content and DataContext to a new ViewModel. In my App.xaml, I have a DataTemplate so that this ViewModel is shown as a certain UserControl. This works great, except that the UserControl is being reused. I can see that because I'm only entering the constructor once. Subsequent adds of ViewModels won't add new UserControls.

My real situation is a little more complex (an MVVM pattern, and a command I need to execute when each UserControl is loaded), but you can reproduce it with this setup:

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Button Click="ButtonBase_OnClick" Grid.Row="0">Click</Button>
        <telerikDocking:RadDocking Grid.Row="1">
            <telerikDocking:RadDocking.DocumentHost>
                <telerikDocking:RadSplitContainer>
                    <telerikDocking:RadPaneGroup x:Name="TheRadPaneGroup">
                        <telerikDocking:RadPaneGroup.ItemTemplate>
                            <DataTemplate>
                                <telerik:RadPane>
                                    <Style TargetType="telerik:RadPane">
                                        <Setter Property="ContentTemplate">
                                            <Setter.Value>
                                                <DataTemplate>
                                                    <!--<userControlEvents:UserControl1></userControlEvents:UserControl1>-->
                                                    <ContentControl Content="{Binding}"></ContentControl>
                                                </DataTemplate>
                                            </Setter.Value>
                                        </Setter>
                                    </Style>
                                </telerik:RadPane>
                            </DataTemplate>
                        </telerikDocking:RadPaneGroup.ItemTemplate>
                    </telerikDocking:RadPaneGroup>
                </telerikDocking:RadSplitContainer>
            </telerikDocking:RadDocking.DocumentHost>
        </telerikDocking:RadDocking>
    </Grid>

Putting the UserControl explicitly in the DataTemplate (and no longer relying on the App.xaml) makes no difference. Putting x:Shared="False" on the Style and/or the DataTemplate makes no difference either.

From what I've read on the interent, this has to do with Virtualization. Is there a way to disable this?

I've made a simple project and put it here. You can see a new ViewModel is added every time (because the milliseconds change for every RadPane that is added), but the second piece of text (the current date, with seconds) does not change, so the UserControl is being reused. I want it to create a new UserControl every time.

If this isn't possible, telling me "no" would be fully acceptable but I must ask:

• Is there a way to​ separate the column order from the drop down order?
• Is there a way to eliminate the Match Case button and never have it try to match the case?
• Is there a way to only allow a top level filter?  So, don't have the + button on a lower level.
• Can I default to "Contains" instead of "Is equal to"?

Thanks for your help,

I have thisRadDataPager

 <telerik:RadDataPager x:Name="radDataPager" Grid.Row="1" Source="{Binding ItemCollection}" DockPanel.Dock="Bottom" PageSize="400" DisplayMode="First, Last, Next, Previous, Text" />

 I bind to it in the ItemsSource of a RadGridView:

  <Controls:RadGridView x:Name="_rgvAdSales"
                              SelectedItem="{Binding Selected​Item, Mode=TwoWay}"
                              ItemsSource="{Binding PagedSource, ElementName=radDataPager}"
                              EnableRowVirtualization="False"
                              AutoGenerateColumns="False"
                              SelectionMode="Extended">...​

 

My columns look like this:

       <Controls:GridViewDataColumn Header="Name" DataMemberBinding="{Binding ​Name}" IsReadOnly="True" />

 

Resharper draws a lin​e under Name (the path of the binding in the column) and says this:

    Cannot resolve property 'Name' in data context of type 'Telerik.Windows.Data.IPagedCollectionView'

 

I have tried to add d:DataContext, but I cannot get that to work.

 

 ​

If I bind the ItemsSource of RadGridView directly to the ItemCollection on the ViewModel, then resharper does not give any warnings.

Do you know of any good way (ie. not causing performance loss) to tell resharper the datatype of the ItemSource or datacontext of the column?


Thanks,

Hello,

 I'm trying to get the RadContextMenu attached to the RadScheduleView to open at the currently selected slot, appointment or empty field using the Apps key (a.k.a. keyboard rightclick).

 

So far I've tried changing the PlacementTarget ​in the RadContextMenu's OnOpening event, but I can't find a way to get the actual source.

RadContextMenu.elementCausedContextMenuOpen is TimeLineRulerPanel, hence RadContextMenu.GetClickedElement<AppointmentItem>() returns null.

Placing the RadContextMenu at MousePoint is not an alternative as it could be anywhere within the application.

 

So is it event possible to get the current scheduler child control to place the ContextMenu at?

 

Thanks in advance!

Jochen

My ItemsSource is a list of records with a Properties bag, rather than having convenient top-level properties

Attempts to define the relationship like this do not work (see error below). Is there some other mechanism?

      var p = new FieldDescriptorNamePair
      {
        ParentFieldDescriptorName = "Properties[\"OrderId\"].Value",
        ChildFieldDescriptorName  = "Properties[\"ParentOrderId\"].Value"
      };
