Hi,

I cannot get the RichTextBox to behave properly with deleting spans cleanly when using a mouse to select a range (parts get left behind, or other words get deleted with it etc) ...and I;m out of time.

Is there a way to completely turn off and disallow range selection ability ?...so no mouse drag/select allowed.

Thanks,

Barry

 Hi,

I read in this, http://www.telerik.com/forums/details-of-features-supporterd, thread that you fully support binding to DataViewManager. However, I can't get it to work. Can you please elaborate on how it's possible to bind the grid to DataViewManager to be able to display the hierarchy of the tables in the underlying dataset.

The background/purpose of my question is this: I have a DataSet returned from our service that contains multiple tables with a parent-child relation, specified with a DataRelation in the DataSet. These tables are fully dynamic which makes it hard to create a proper ViewModel of it. Hence, I want to display the data with its relation directly in the grid.

This works well when binding the grid directly to the DataSet. The hierarchy is correctly displayed in the grid. However, my next demand is that it should support update notification of the underlying data so that the grid automatically refreshes when a value in a DataTable changes. That's why I figured I should bind to the DataViewManager of the DataSet instead, but that doesn't work. Binding to the parent table's DataView works, but then the hierarchy is lost (and I get a DataRelation column too).

I recently updated my Telerik UI for WPF version to 2017.1.117.45 and since then it seems that the property AllowFinish of the RadWizard is ignored (and possibly the others Allow* properties). When I set the value of AllowFinish to False (directly or with a binding) the Finish button is always enabled.

Could you confirm if this is a bug like in this topic or if I might be doing something wrong? (but I think that it was working well before the update)

 

Thanks in advance.

We use VirtualQueryableCollectionView because our data sets are very large. For the same reason, we need to restrict the number of items the user can select. We do this by hooking into the SelectionChanging event and if the number selected exceeds our limit we put up a message telling them they need to select fewer rows. We then cancel the select.

Presumably the way the user selected so many rows was to select a row and then scroll quickly to a page much further down and shift-click another row. The problem is that when we show the message to say they exceeded the limit, the RadGridView is making the calls to load all the rows that would be part of that selection. This defeats the point of having the limit. Those rows should only be loaded on a SelectionChanged, not a SelectionChanging, since the latter can be cancelled. Our entire application locks up and eventually gets an out-of-memory from trying to load all the rows that shouldn't be loading.

Is there a way to stop the grid from loading those rows before the SelectionChanged event has occurred. 

Thank you.

All fonts which are the sub font style of a font family in c:\windows\fonts are not able to set to bold or italic( bold/Italic are not shown in richtextbox but when exported to word, they are showing correctly). Is there any solution on it?

Some examples: Arial Black, Arial Narrow, Bodoni MT Black, Bodoni MT Condensed,Calibri Light, Franklin Gothic Medium, ...

Hello,
There is a way to Binding SelectedItems of a telerik:RadComboBox with AllowMultipleSelection="True" that works in a runtime?
Our purpose is to create a multiple combobox with checkboxes (bindable from a property)

At the movement I have this code, but it doesn’t works correctly because SelectedItems don’t exist


        public class Agency(){
            public string Text { get; set; }
            public bool IsChecked { get; set; }
        }

        private ObservableCollection<Agency> Agencies;
        public ObservableCollection<Agency> Agencies
        {
            get
            {
                return this.selectedAgencies;
            }
            set
            {
                if (this.selectedAgencies != value)
                {
                    this.selectedAgencies = value;
                    this.OnPropertyChanged(() =>this.SelectedAgencies);
                }
            }
        }


        private ObservableCollection<Agency> selectedAgencies;
        public ObservableCollection<Agency> SelectedAgencies
        {
            get
            {
                return this.selectedAgencies;
            }
            set
            {
                if (this.selectedAgencies != value)
                {
                    this.selectedAgencies = value;
                    this.OnPropertyChanged(() =>this.SelectedAgencies);
                }
            }
        }

        <telerik:RadComboBox x:Name="radComboBox"
                             ItemsSource="{Binding Agency}"
                             AllowMultipleSelection="True"
                             SelectedItems="{BindingSelectedAgencies}">
            <telerik:RadComboBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <CheckBox VerticalAlignment="Center"IsChecked="{Binding IsChecked}"></CheckBox>
                        <TextBlock Margin="5" Text="{Binding Text}"/>
                    </StackPanel>
                </DataTemplate>
            </telerik:RadComboBox.ItemTemplate>
        </telerik:RadComboBox>

This may be a long-shot as I don't see it documented anywhere, but can I omit the style tag but still trigger the CssClassExporting event. What I need is to pull the extracted styles into a separate css file. I can parse the files manually if need be, but if there is some combination of configuration options I'm missing here please correct me.  Here is what i have at the moment.

 

HtmlFormatProvider provider = new HtmlFormatProvider();            

provider.ExportSettings.DocumentExportLevel = DocumentExportLevel.Fragment;          

provider.ExportSettings.StylesExportMode = StylesExportMode.Classes;                      

provider.ExportSettings.SpanExportMode = SpanExportMode.DefaultBehavior;                         

provider.ExportSettings.ExportStyleMetadata = true;          

// Dont export the document styles

provider.ExportSettings.StyleRepositoryExportMode = StyleRepositoryExportMode.DontExportStyles;             

// Export font style as style rather than tag          

provider.ExportSettings.ExportFontStylesAsTags = false;             

// Only create styles which need be             

provider.ExportSettings.ExportLocalOrStyleValueSource = true;             

provider.ExportSettings.CssClassExporting += ExportSettings_CssClassExporting;             

var data = provider.Export(RadDocument);             

Although I am not using this control in a DataForm, it is definitely derived from DataFormDataField. As you can see I am getting an exception in the Xaml designer.  It compiles fine and displays fine at runtime; however it prevents the Xaml UserControl from displaying in the designer.  I get many, many of these errors.  Can anyone give me a hand with this?

Thanks ahead of time,

Steve
