We have a complaint from a customer, and aren't sure of how to deal with it.

The problem is that when we're displaying a RadDataForm with IsEnabled="False", they are unable to select the text on the form and copy it to the clipboard. Which, apparently, is a significant problem for them.

It's an easy enough problem to replicate. You can see it in your example at https://github.com/telerik/xaml-sdk/tree/master/DataForm by simply setting IsEnabledFalse="True" on the RadDataForm.

Is there another simple way of making a form readonly, that doesn't cause this problem?

Ok, I figure I'm missing something blindingly obvious here. I have a class, which in turn has a list of floats within it (there is more in the class including a datetime for the category binding):


My LineSeries's ItemsSource is bound to an observablecollection of MyClass. Then the ValueBinding is set to "aName". When I do this all is well in the world and I get exactly what I wanted. Now I want to have item in index 1 of the "aList" as a ValueBinding. If I put in "aList[1]" I get an error stating that it can't find the property.

So where am I wrong please?

The property is visible in property grid, even after setting the browsable attribute to false.Why?

Hi All,

We have a custom field NoteNumberingField inherited from CodeBasedField, overridden CopyPropertiesFrom , CopyPropertiesFromCodeExpression and
BuildCodeOverride.

NoteNumberingField shows a number in the span and it is rendered below in the xaml. 

<t:FieldRangeStart AnnotationID="2">
<t:NoteNumberingField DateTimeFormatting="" DisplayMode="Result" GeneralFormatting="" NumericFormatting="" Text="1" xmlns:t="clr-namespace:KPMG.TMT.Trinity.Documents.TelerikWpf.Fields;assembly=KPMG.TMT.Trinity.Documents.TelerikWpf" />
</t:FieldRangeStart>
<t:Span FontFamily="Comic Sans MS" FontSize="34.67" Text="1" />
<t:FieldRangeEnd AnnotationID="2" />

When I change the font size of the text from the telerik font size dropdown, I see the overridden method CopyPropertiesFrom get fired and this copies the properties.

But when I change the font size of the same span by code, I dont see the CopyPropertiesFrom being fired as a result I lose all the properties being modified on the span.

So when I say UpdateAllFields on Richtextbox it bring back the default style of the text rather than the previous style what I changed.

In essence when I call RadDocumentEditor.UpdateAllFields, span (inside the field) properties are retained if I have changed using telerik font size drop down, 
but I lose all properties if span properties are changed by code.

Could some one help me in this issue please ? 

Thanks in Advance

Hello

I have a problem with recurrence pattern.

Appointments are loaded for a selected timespan (for example April 2015).

The problem is, that I don't see any ​recurrence-​appointments, when the main-​appointments ​are not in the ​selected timespan, because main-appointments are not loaded and therefore the recurrence-appoin​tments by recurrencerule are also not loaded.

How can I detect all ​recurrence-appointments for the selected timespan without loading all the main-appointments?

Hello,

I created a chart view with two trends, each trend has a time series data set of 30000 data points.

It is very slow to render the trends, and is also very slow to zoom in and out.

Is there a way to optimize the render for this kind of data?

 Thanks

Hi, dear support.

I am trying to set a custom tooltip for when the mouse is hovering over Gantt Events.

Here is fragment of my code:

...

 <Grid DataContext="{StaticResource SchedulerViewModel}">
        <controls:RadGanttView x:Name="ganttView"  

            TasksSource="{Binding Tasks}"
            MouseDoubleClick="ganttView_MouseDoubleClick" DataContext="{Binding Tasks}" SelectionChanged="ganttView_SelectionChanged">

            <controls:RadGanttView.Resources>
                <Style TargetType="{x:Type controls:EventContainer}">
                    <Setter Property="Background" Value="{Binding OriginalEvent.Background}"/>
                    <Setter Property="ToolTip" Value="{Binding OriginalEvent.TaskFullDescription}"/>
                </Style>
                
            </controls:RadGanttView.Resources>

...

The class property TaskFullDescription bound to the tooltip provides a string with all task details. The property Background provided in the same class - works and changes the Event container background, but the property TaskFullDescription has no effect and only the default tooltip is shown.

What is the proper way of customising a tooltip, when it needs to set a text provided by a method.  

 

Thank you, Sergey

I want the LineStroke here in the pointtemplate is the line's color, but I can't get it.

I am binding a DataTable to RadGridView and AutoGenerateColumns="True",
Following are the columns I have,
dt.Columns.Add("Text", typeof(string));
dt.Columns.Add("Number", typeof(double));
dt.Columns.Add("CustomType", typeof(Custom));
Custom is a Enum as follows,
public enum Custom
    {
        One,
        Two,
        Three
    }
Now when I bind the DataTable to RadGridView it displays Data correnctly, but when I try to change the value of custom columns I am not getting dropdown to select a value from Enum instead when I enter in edit mode it displays the Id of the selected Enum.
I tried changing RadGridViewDataColumn to RadGridViewComboBoxColumn in AutoGeraratingColumns Event but not able to make it working.
Please help as its pretty urgent and important.
Attached is the screenshot for the same. 
Thanks in Advance!!!

Hello,

I'm using the RadTreeView with only ONE root node. My ItemsSource is FolderData. FolderData has only one Item - the root node. I'm using

​ for allowing the dropping in special nodes. 

 

How can I disable the dropping next to root node? I want to avoid to have more than one root nodes. Is it possible?
