Hello,
I've done a new template and style to a RadComboBox, but now I can't find where to style the SelectionBox(Item).
I don't want the behavior that is generated by the office theme.

Where can i edit those properties?

Thank you!

Exception pressing enter after column sorting

Hello guys,
we're getting an "InvalidOperationException" in RadGridView that can be reproduced in your WPF 2011 Q2 Demo.

- please start "RadControls for WPF Q2 2011 Demos"
- select Highlights --> GridView
- select the first row by clicking with the mouse (Nancy)
- press "enter" two times --> all ok
- sort the list clicking on a column heading, i.e. "Phone"
- press "enter" --> Exception !!!!

If necessary I could send you a stack trace from the same exception we're experiencing in our application.

Best regards
Oliver

Customizing the RadInsertSymbolDialog

Hi,

My application has a requirement to limit the symbols that can be inserted into the RichTextBox control. How do I customize the Insert Symbol dialog to achieve that? In addition, I have similar requirements for the FontPropertiesDialog to limit the font family selection.

Thanks,

Cell and Triggers

Hi,

I would like to run a storyboard which will effect the border when a user enters a cell. I presume this can be achieved through a trigger.
Alternately / also I would like show a different control template, when the enters the cell and leaves the cell

My problem is that I do not which property to attach the trigger to.

for my column style I am using this ControlTemplate.

<ControlTemplate.Triggers>

</Trigger>

</ControlTemplate.Triggers>

</Border>

</ControlTemplate>

RecurrenceDays.AddDay Question

I am converting an outlook apppointment to a scheduleview appointment, in converting the recurrence I am trying to build a RecurrenceDays, I may be missing something but I have not been able to find any documentation on building a RecurrencePattern from scratch so I am winging it.

When I step through the code below everything is fine except RecurrenceDay.AddDay doesn't do anything, The result is that telerikdays is always None. What am I missing?

pat.Frequency = RecurrenceFrequency.Weekly;

pat.MaxOccurrences = week.NumberOfOccurrences;

Microsoft.Exchange.WebServices.Data.DayOfTheWeekCollection days = ((Microsoft.Exchange.WebServices.Data.Recurrence.WeeklyPattern)week).DaysOfTheWeek;

RecurrenceDays telerikdays = new RecurrenceDays();

foreach (DayOfWeek d in days)

{

switch (d)

{

case DayOfWeek.Friday: telerikdays.AddDay(RecurrenceDays.Friday); break;

case DayOfWeek.Saturday: telerikdays.AddDay(RecurrenceDays.Saturday); break;

case DayOfWeek.Sunday: telerikdays.AddDay(RecurrenceDays.Sunday); break;

case DayOfWeek.Monday: telerikdays.AddDay(RecurrenceDays.Monday); break;

case DayOfWeek.Tuesday: telerikdays.AddDay(RecurrenceDays.Tuesday); break;

case DayOfWeek.Wednesday: telerikdays.AddDay(RecurrenceDays.Wednesday); break;

case DayOfWeek.Thursday: telerikdays.AddDay(RecurrenceDays.Thursday); break;

}

pat.DaysOfWeekMask = telerikdays;

RadTabItem HeaderTemplate not responding to binding to UserControl object properties

I am using the RadTabControl to host UserControls within its tabs. Its ItemsSource property is set to an ObservableCollection<UserControl>. So, to properly name these tabs I had planned to create a HeaderTemplate and simply bind to the Name property of my UserControl, converting it to a user friendly string of course. To do this I used the following:

TabControl declaration:

<telerik:RadTabControl x:Name="radtabVariableControlsContainer" Margin="0" d:LayoutOverrides="GridBox" Grid.Column="1" BorderBrush="{x:Null}" ItemsSource="{Binding MainContentControls}" SelectedItemRemoveBehaviour="SelectPrevious" ItemContainerStyle="{StaticResource MainContentItemContainerStyle}"/>

ItemCotainerStyle:

<Style x:Key="MainContentItemContainerStyle" TargetType="{x:Type telerik:RadTabItem}">

<Setter Property="HeaderTemplate" Value="{StaticResource ContentAreaTabHeaderTemplate}"/>

</Style>

Finally, the HeaderTemplate:

<DataTemplate x:Key="ContentAreaTabHeaderTemplate">

<TextBlock Text="{Binding Name, Converter={StaticResource TabHeaderTextConverter}}" FontFamily="Arial" FontSize="13.333"/>

</DataTemplate>

With this setup, nothing shows up for the header text. The converter is not the issue because removing it does not solve the problem. It seems to be that the Binding cannot execute at Runtime because when editing the template in Blend, the Binding works and shows the correct value. Also, putting any clear text in for the textblock's text property works.
