Hi,

I have three columns (Eg:ID ,Name, Location) ID column is readonly. When i insert new row by setting ShowInsertRow="True" and CanUserInsertRows="True" i need to enter the value for the ID column. How to achieve this? I am following MVVM pattern.

Thanks in Advance. 

Greetings,


I have been evaluating your excellent RadPDFViewer control which I am pleased with.

But the ScaleFactor does not appear to be working? I set in code and nothing happens. I also set it in the DocumentChanged event as you suggest and still nothing?

I hope you can help us?

Any help would be greatly appreciated.

This is really urgent since I am a freelance contractor working on a short-term project and the client needs a very quick turn around, ideally before my contract ends very soon! :)

Many thanks,
David.
P.S. It also appears REALLY slow when used in a frame, has anyone else seen this?

How to Suspend Find Replace Dialog when Pressing Ctrl +F

hi

i was given a solution to enable to re-template the AxisLabel2d controls which worked fine. See attached

When i resize the window, the labels revert back to the defaulted state (timedate), initally it is fine.

My converter does nothing but return a string. I restyle using the code below (as per the suggestion by you guys)

            ChartArea area = _CA;
            HorizontalAxisLabels2D axisLabelsContainer = area.FindChildByType<HorizontalAxisLabels2D>();
            var axisLabels = axisLabelsContainer.ChildrenOfType<AxisLabel2D>();
            System.Windows.Style style = _GD.Resources["CustomLabel"] as System.Windows.Style;
            foreach (var item in axisLabels)
            {
                item.Style = style;
            }

    public class GetTextConverter : IValueConverter, IMultiValueConverter
    {
        public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
        {
            return "I Am HERE";
        }
       
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return "I Am HERE";
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException();}
        public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) { throw new NotImplementedException(); }
    }

 


<Style x:Key="CustomLabel" TargetType="telerikCharting:AxisLabel2D">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerikCharting:AxisLabel2D">
                <Border Background="{TemplateBinding Background}">
                    <Border.DataContext>
                        <MultiBinding Converter="{StaticResource GetTextConverter}">
                            <MultiBinding.Bindings>
                                <Binding Path="DataContext" ElementName="_GD"/>
                                <Binding Path="CurrentIndex"/>
                            </MultiBinding.Bindings>
                        </MultiBinding>
                    </Border.DataContext>
                    <TextBlock Style="{TemplateBinding ItemLabelStyle}" Text="{Binding .}">
                        <TextBlock.LayoutTransform>
                            <RotateTransform x:Name="PART_RotateTransform" />
                        </TextBlock.LayoutTransform>
                    </TextBlock>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Hello,

This exact same sample works when using a Window rather than a RadWindow.

Does anybody have any idea why this is or what I can do to resolve it?

Many thanks.

is this possible?

I am using the RadRichTextBox to input and display various types of data. So far text input works fine. However when I copy and paste an image it seems to appear in the RadRichTextBox but the actual image is invisible. I would like to have text, tables, images and files if possible inside my RadRichTextBox. Here's some code that I've tried thus far. As I understand it XamlDataProvider takes a string in xaml format as its data source. Which is fine but then I don't understand how binary files like images are handled. A code sample in the mvvm pattern would be great. Thank you.

is it possible to perform Find Replace in MVVM?

Hi,

I have a wpf desktop app using your radrichtext box and I find it fits my purpose very well.
My raddocument uses a lot of custom annotations.

Other than silverlight, do you intend to create a web app say in your kendo or asp ajax  product ranges that is capable of loading xaml docs?
This would be a really useful feature for me when I want to display my documents via the web to my customers.

Thanks,

Rob

Is it possible somehow to bind the Ticks source to a list of strings? For example A, B, C, D, E etc

I want to use the slider to change between different modes rather then just use its numerical values :)

Kind regards
Christopher
