When I export as an MS Word file, and then open this document in Word, the Style selector shows some standard styles provided by the RadDocument (e.g. "Heading 1" etc.), plus the styles I have defined.
What I want to be able to do is to replace the default "Header x" styles with styles that I have defined. Is this possible?

Hi

Here is my collection
public ObservableCollection<dynamic> Items{get; set;}

My binding is like:
radGridView.ItemSource = Items.Where(i => i.IsVisible);

So it is binding with Enumerable<dynamic> instead of Items and hence getting disconnected. Then if is add/delete any item in ObservableCollection<dynamic>, no reflection. I do not want to rebind grid as i need to preserve the scrolling.

Please help me to find a solution.

Thanx

Hello,

im interested in converting an existing usercontrol which is made with the microsoft charts to the telerik Chartview. 
For that i would need the ability to drag and drop a datapoint in the displayed graph and change its position/value in the graph by dragging it.

Is this possible with the chartview control? if so then how can i achieve this behavior? 

In case my description isnt clear there is an example in the Forms Samples Environment of what i need to do: 
Content Tab > Chart Features > Interactive Charting > Selection > Changing values by dragging.

Hello,

I'm trying AnimationSelector Expand/Collapse not work in WPF in Silverlight not any problem. Thanks.

Hello,
I have a problem with grid repainting/coloring the RadHorizontalLinearGauge that is inside my colum cell template when the datasource of the grid is changed. Let me explain my scenario, I have the following class:
As you can see, it has 4 properties and one of them is the list of data to be binded on the grid. My view model contains only the list of Strands. So I made an itemcontrol that has as source the list of strands and creates a radio group button for each element in the list. The ItemsSource of the grid is binded to the selectedStrand, and the data are changing in base of the selected radio button. Here is the xaml
The first time that the application starts everything is ok and for all the rows the gauges are colored as you can see in gaugefirstload.jpg. But when the other radio button is selected and the grid's itemssource is changed the gauges are drawn inside the grid cells but there are not colored and I see them black & white as in GaugeAfterRadioChanged.jpg. When I play with the scroll the coloring of the gauges is casual as in GaugeAfterRadioChangedAndScroll.jpg. I tried to use the Rebind() of the grid, but it didn't help. Is there some event or something that can be used to force the grid to repaint itself and color the gauges when radio button changes?
I can send you the sample solution that I made and where you can see this behaviour, maybe it woud be easier for you to understand and simulate the problem, just tell me how cause the zipped solution has around 30mb.
Thanks
Kindly regards

I'm facing this weird issue of the appoint filter not working the second time around.

My Application has calendars for different users.

When I first load the scheudle view (calendar) and try to filter it all works well. But then when I try to change the calendar for another user and then apply filter on it, nothing seems to happen. 

When I debugged, I realised that the predicate does hit all the time the filter is supposed to be called. But the second time around the predicate doesn't call the filter appointment method at all. I'm puzzled as to why this happens and need you to help me. 

As a background, I've bound the predicate (FilteredAppointments) to the appointment filter property in the xaml and the predicate then calls the filter appointment method (which returns a bool for each appointment). Also, all these are in separate classes, i.e. the predicate and the filterAppointments method.

Please help, need to resolve this ASAP.

Hi,

There is GridView with some columns and want to display total of one of the column which is having data of type System.Double. I had look at the same and tried to implement the same but it didn't work and end-up with following exception.

Code
<telerik:GridViewDataColumn DataMemberBinding="{Binding TravelRate, StringFormat=c}"
                                            UniqueName="TravelRate"
                                            Header="Travel Rate"
                                            MinWidth="100">
                    <telerik:GridViewDataColumn.AggregateFunctions>
                        <telerik:SumFunction Caption="Sum: "
                                             ResultFormatString="{}{0:c}"
                                             SourceField="UnitPrice" />
                    </telerik:GridViewDataColumn.AggregateFunctions>
</telerik:GridViewDataColumn>

Exception
No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic.

I also had a look at another post where it's mentioned create custom aggregation function. I tried it but didn't get any success.

Code
public class SumFunction : EnumerableSelectorAggregateFunction
    {
        protected override string AggregateMethodName
        {
            get { return "Sum"; }
        }

        protected override Type ExtensionMethodsType
        {
            get
            {
                return typeof(Amounts);
            }
        }
    }

    public static class Amounts
    {
        public static Double Sum<T>(IEnumerable<T> source, Func<T, Double> selector)
        {
            return source.Select(selector).Aggregate(Double.Parse("0"), (t1, t2) => t1 + t2);
        }
    }

Can please some one help me with this?

Thanks.

Is there a way to customize the Enum dropdown list for a field?  We have different permission settings for our applications, and we have to limit options for some users.  An Example would be to have the following code:

Enum Produce
Apples
Oranges
Pears
Peaches
End Enum

Where we can set the 'Produce' field for some users to be able to see and select Apples and Oranges only, while others can  see and select the full list.

I have been directed to this article: http://www.telerik.com/help/wpf/radcombobox-howto-enable-disable-radcombobox-items.html, but that deals with setting it up with Xaml.  I need to change the list on the fly at runtime, and have accessed the RadComboBox with this line of code:

ComboBoxItems = RadPropertyGrid1.ChildrenOfType(Of RadComboBox)()

But now that I have it, how can I manipulate the list?  I have autobinding on, so when I try to clear or set the items manually, I get the error:

"Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead."

Hello,
