Since Update (2013.1.403.45) RadExpander looking for Windows8Touch resource

Since applying the aforementioned update I can no longer get my RadExpander to display in the designer.
I get a Design Time warning of "cannot locate resource 'themes/genericwindows8touch.xaml'".

I am using the Windows8 Theme(non touch version) implicitly, which was working as expected prior to this update.

DataBinding with DataTemplate when AutoGenerateColumns="true"?

Hello,

I have a RadGridView that will be populated by a dynamically generated DataTable. I have therefore set the RadGridView property as follows: AutoGenerateColumns="True". My DataTable will contain dates, strings and integers. I want to be able to use a DataTemplate for each data type in the automatically generated columns of the grid. For instance, for string columns, I will want to use a TextBox with text wrapping, which accepts returns and has a certain maximum width.

For the purpose of this question, my datatable will be created and bound to the RadGridView as follows:

DataTable table = new

DataTable();

table.Columns.Add(

new DataColumn("Date Column 1", typeof

(DateTime)));

table.Columns.Add(

new DataColumn("Date Column 2", typeof

(DateTime)));

table.Columns.Add(

new DataColumn("String Column 1", typeof(string

)));

table.Columns.Add(

new DataColumn("String Column 2", typeof(string

)));



DataRow row1 = table.NewRow();

row1[table.Columns[0]] = DateTime.Now;

row1[table.Columns[1]] = DateTime.Now.AddDays(10);

row1[table.Columns[2]] =

"some string"

;

row1[table.Columns[3]] =

"some other string"

;



table.Rows.Add(row1);

radGridView1.ItemsSource = table;

And my RadGridView currently looks like:

<telerik:RadGridView HorizontalAlignment="Stretch" Name="radGridView1" VerticalAlignment="Stretch" AutoGenerateColumns="True"

<telerik:RadGridView.Resources

<DataTemplate x:Key="TextCellEditorTemplate"

<TextBox Background="LightYellow" MaxWidth="250" TextWrapping="Wrap" AcceptsReturn=

"True"

                        Text="{Binding WHAT_GOES_HERE?}" />

</DataTemplate

<DataTemplate x:Key="DateTimeCellEditorTemplate"

...

</DataTemplate

<DataTemplate x:Key="IntegerCellEditorTemplate"

...

</DataTemplate

</telerik:RadGridView.Resources

</telerik:RadGridView>

Can you help me specify the binding of the text property of the DataTemplate that uses a TextBox? It should be a two-way binding with the underlying cell in the DataTable. Could you provide me with a basic working example of what I am trying to achieve? This would be greatly appreciated.

Thanks!

How to set Style for all cells?

How do you set the style for all cells in an autogenerated GridView in a designer friendly manner?

ItemContainerStyle has no effect.

it is possible to handle Columns.CollectionChanged and set Column.CellStyle there, but that approach requires code behind and is invisible at design time.

Customize group header

Hi I am trying to customize the look of the group header with the use of data templates. When ever I do this no group header is displayed. I have tried to to use the Group Header template selector and to modify content template within the style selector both have th same results. Here is the xmal I am trying to use. I have verified that the event creation style is being applied.

<ecu:GroupHeaderStyleSelector x:Key="GroupHeaderStyleSelector">

<ecu:GroupHeaderStyleSelector.DateStyle>

<Style TargetType="telerik:GroupHeader">

<Setter Property="Visibility" Value="Collapsed"/>

</Style>

</ecu:GroupHeaderStyleSelector.DateStyle>

<ecu:GroupHeaderStyleSelector.EventCreationStyle>

<Style TargetType="telerik:GroupHeader">

<Setter Property="Visibility" Value="Visible"/>

<Setter Property="Height" Value="100"></Setter>

<Setter Property="VerticalAlignment" Value="Top">

</Setter>

<Setter Property="ContentTemplate">

<Setter.Value>

<DataTemplate>

<TextBlock>Audio</TextBlock>

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

</ecu:GroupHeaderStyleSelector.EventCreationStyle>

</ecu:GroupHeaderStyleSelector>

On the control I am doing the following

<telerik:RadScheduleView Grid.Row="2"

DialogClosing="eventsTimeline_DialogClosing_1"

AppointmentsSource="{Binding Events, Mode=TwoWay}"

NavigationHeaderVisibility="Collapsed"

ShowDialog="RadScheduleView_ShowDialog"

ResourceTypesSource="{Binding EventTypes}"

TimeRulerItemStyleSelector="{StaticResource TimeRulerItemStyleSelector}"

GroupHeaderStyleSelector="{StaticResource GroupHeaderStyleSelector}"

AppointmentEditing="RadScheduleView_AppointmentEditing"

AppointmentSaving="eventsTimeline_AppointmentSaving"

AppointmentCreating="eventsTimeline_AppointmentCreating_1"

AppointmentCreated="eventsTimeline_AppointmentCreated"

AppointmentSelectionChanged="eventsTimeline_AppointmentSelectionChanged_1"

AppointmentDeleting="eventsTimeline_AppointmentDeleting_1"

AppointmentDeleted="eventsTimeline_AppointmentDeleted_1"

DeleteAppointmentConfirmDialogStyle="{StaticResource DeleteEventConfirmDialogStyle}"

ResizeHighlightStyle="{StaticResource EventResizeHighlightStyle}"

Name="eventsTimeline" VerticalAlignment="Top">

<telerik:RadScheduleView.ViewDefinitions>

<telerik:DayViewDefinition

VisibleDays="1"

MajorTickLength="5min"

MinorTickLength="1min"

MinTimeRulerExtent="5000"

TimerulerMajorTickStringFormat="{}{0: HHmm}"

DayStartTime="00:00:00" DayEndTime="3:00:00" Orientation="Horizontal">

</telerik:DayViewDefinition>

</telerik:RadScheduleView.ViewDefinitions>

<telerik:RadScheduleView.DragDropBehavior>

<ecu:EventCreationDragDropBehavior />

</telerik:RadScheduleView.DragDropBehavior>

<telerik:RadScheduleView.AppointmentStyleSelector>

<ecu:EventStyleSelector

AudioEventStyle="{StaticResource AudioEvent}"

OdorEventStyle="{StaticResource OdorEvent}"

LightingEventStyle="{StaticResource LightingEvent}"

SmokeEventStyle="{StaticResource SmokeEvent}"/>

</telerik:RadScheduleView.AppointmentStyleSelector>

<telerik:RadScheduleView.GroupDescriptionsSource>

<telerik:GroupDescriptionCollection>

<telerik:ResourceGroupDescription ResourceType="Event Types" />

</telerik:GroupDescriptionCollection>

</telerik:RadScheduleView.GroupDescriptionsSource>

</telerik:RadScheduleView>

Everything worked as intended until I tried to modify the control template. When I tried using the template selector I got the exact same results.

Checkbox states

Hello, Telerik team!
I'm stumbled into some little UI inconveniences using RadGridView.
I use checkbox column bound to IsSelected property of my Model.
Item source of RadGRidView is of ObservableCollection<Model> class:

<controls3:RadGridView x:Name="Sports" ShowGroupPanel="False" ItemsSource="{Binding AllSports}"

AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed" CanUserSelect="False" ScrollViewer.HorizontalScrollBarVisibility="Disabled">

<controls3:RadGridView.Columns>

<controls3:GridViewCheckBoxColumn DataMemberBinding="{Binding IsSelected}" Header="Chosen" ForceCursor="True" IsThreeState="False" />

<controls3:GridViewDataColumn Width="239" DataMemberBinding="{Binding name}" Header="Name"/>

</controls3:RadGridView.Columns>

</controls3:RadGridView>

when I want to check the checkbox, it takes three clicks to make it checked: first accordin row is selected, second click select a cell, and only on third click the box is checked.
I understand that it should be a lame problem, but nevertheless, it would be very kinf of you if you help me!

How to bind to SelectedItems

Hello,

I am trying to two-way bind to a List<Stores> in order to pre-populate the auto suggest box and get its updated values. I tried using the following:

<telerik:RadAutoCompleteBox Name="radAutoCompleteBox1" Grid.Column="2" Grid.Row="0"

DataContext="{Binding DetailViewModel}"

SelectionMode="Multiple"

WatermarkContent="Type a name"

TextSearchMode="Contains"

ItemsSource="{Binding BookstoreLookup}"

DisplayMemberPath="ShortName"

TextSearchPath="ShortName"

AutoCompleteMode="Suggest"

SelectedItems="{Binding SelectedNoticeItem.Bookstores, Mode=TwoWay}"

/>

However, I keep getting "Collection was of a fixed size" exceptions. I've tried no Mode too.

BookstoreLookup is an ObservableCollection<BookstoreModel> and SelectedNoticeItem.Bookstores is a List<BookstoreModel> (I also tried ObservableCollection).

Thanks for your help.
