Hi,

     I'm using RadGridView to show List of objects. Suppose one row contains a common cell(GridViewDataColumn) and a combobox cell(GridViewComboBoxColumn). After I edited the  common cell everything goes well, but while the combobox cell edited the RowEditedEnded event will be raised. In fact I stll need to edit other cells. Any suggestions to prevent this?

Thank you!

Hello,

 

I merged themes in Application.Xaml like this

   <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.FixedDocumentViewers.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

And this is working correctly, but as soon as I merge this file (which I need for my project) every ordinary button in my project merges this Expression dark theme (which I do not want).

<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>

 

 I am aware that merging System.Windows with this theme changes button style but in this case it is not merged, and it still looks different.

So, two questions:

1.) How do I merge Telerik.Windows.Controls.Navigation with this Theme without merging ordinary buttons also with this theme?

2.) Is there any way I can merge this theme to System.Windows this but only to tooltips and scrollbars?

 

Thank you

Hello All.

I've a GridView with a checkbox column 

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding IsSelected, Mode=TwoWay, UpdateSourceTrigger= PropertyChanged}" .../>


Now it seems the binding is updated only on lost focus (for example, when clicking on another cell/row) and not according to the UpdateSourceTrigger= PropertyChanged.

This is a problem for me, since I've a menu bar which has commands (like delete) which work on the selected rows, and when the menu item is clicked, the Checkbox binding isn't yet updated. Basically you have to select the checkbox, click on the grid outside the checkbox, and only then click on the menu item.Is there indeed a problem here, or am I doing something wrong? Should I simply use GridViewDataColumn with checkbox instead of GridViewCheckBoxColumn?

Yours,
Roee

Given the following (simplified) class...

    class SearchResultsViewModel
    {
        public IList Results { get; }
        public SearchCriteria Criteria { get; }
    }

And the following (also simplified) WPF DataTemplate's...

    <DataTemplate DataType="{x:Type viewModels:SearchCriteria}">
        <StackPanel>
            <!-- Various controls used to display/edit  the SearchCriteria class properties-->
        </StackPanel>
    </DataTemplate>

    <DataTemplate DataType="{x:Type viewModels:SearchResultsViewModel}">
        <telerik:RadDocking>
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup>
                        <telerik:RadDocumentPane Visibility="Collapsed"
                                                 CanUserClose="False">
                            <telerik:RadBusyIndicator BusyContent="{Binding Path=BusyContent}"
                                                      IsBusy="{Binding Path=IsBusy, Mode=OneWay}">
                                <telerik:RadGridView ItemsSource="{Binding Path=Results}" />
                            </telerik:RadBusyIndicator>
                        </telerik:RadDocumentPane>
                    </telerik:RadPaneGroup>
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>
            <telerik:RadSplitContainer InitialPosition="DockedLeft">
                <telerik:RadPaneGroup IsContentPreserved="True">
                    <telerik:RadPane CanUserClose="False"
                                     CanFloat="False"
                                     DataContext="{Binding Path=Criteria}"
                                     Header="Search Criteria"
                                     IsPinned="False">
                        <ContentPresenter Content="{Binding}" />
                    </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking>
    </DataTemplate>

When I display the SearchResultsViewModel (using a ContentPresenter), I see - as expected - a list of the results along with a tab on the left of the page with the header "Search Criteria"; however when I then click on the tab to open the associated panel and view the properties of the "SearchCriteria" class I see a repeat of the whole "SearchResultsViewModel" DataTemplate instead of just the properties of the "SearchCriteria" using its own DataTemplate. This then repeats recursively so each time I click on the tab it opens yet another copy.

I have also tried setting "Content={Binding Path=Criteria}" on the "ContentPresenter" instead of setting the "DataContext={Binding Path=Criteria}" on the "RadPane" but this makes no difference.

I use the DataTemplate for the "SearchCriteria" elsewhere within the application and it is called upon based upon the DataType being shown rather than any specific reference to the specific template so I do not want to have to give the template an "x:Key" and then reference it specifically here either but then I do not expect to have to do this as it works elsewhere.

What am I doinng wrong to make the ContentPresenter within the second DataTemplate show the "SearchCriteriaViewModel" DataTemplate instead of the "SearchCriteria" DataTemplate?

Hello,

The French translation for the control are not all correct:

  • RibbonViewLayoutModeButtonContent should be "Ruban simplifié"
  • RibbonViewQATShowBelow should be "Afficher au-dessous du ruban"
  • RibbonWindowMaximize should be "Agrandir"
  • RibbonWindowMinimize should be "Réduire"
  • RibbonWindowRestoreDown should be "Niveau inf."

The last theree are those used by Windows in their tool-tips.

Hello,

I'm trying to dynamically change the resources of the control, in order to change the language of the application without restarting.

First, it's a shame that not all of your controls work with just setting "UseDynamicLocalization = True" and changing the "LocalizationManager.Manager.Culture" property. It complicates the work of application developer...

 

Back to the RadMap. I've implemented code to reload the template of the control after changing the resources and it doesn't work correctly. Almost all of the control changes the texts, excepted for the "layout/mode selection" of all the providers, as you can see with the screenshots: after changing the texts, these ones remains in English.

My code for the loading of the resources is correct because it works for all the other part of the application (and of the map). If I close the application and then starts it again, the texts are in French.

 

My application is using a custom localization manager, so the texts can be loaded from text files.

Hello,

There are some errors in the French translation for RadMap:

  • MapCanvasDarkCommand should be "Fond sombre"
  • MapCanvasGrayCommand shoud be "Fond gris"
  • MapCanvasLightCommand should be "Fond clair"
  • MapOsmTransportCommand should be "Transports"
  • MapRoadCommand should be "Routes"
  • MapRoadOnDemandCommand should be "Routes sur demande"
  • MapShadedReliefCommand should be "Reliefs ombrés"
  • MapTerrainBaseCommand should be "Terrain"
  • MapTopographicCommand should be "Topographique "
  • MapWestChar should be "O"

Note that the "mile" abbreviation is officially "mi" and not "ml", which stands for "milli liter", also wrong in English and perhaps. in other languages.

For the first 3 resources (and some others...), I've never see them in the control, so I'm not sure whether they are really used...

Hello,

The documentation about localization is missing the RibbonViewMinimizeRibbon resource key.
