Copy command copies the binding information instead of data.

Hi,

I have a copy menu with command = Copy and CommandTarget=MyRadGridView. Now when i click copy and paste it in excel, it pastes the name of the binding object for the columns where I'm using converter to concatenate two fields. For columns which have direct binding defined it copies the data.

Copy command:

<MenuItem Header="Copy" InputGestureText="Ctrl+C" Command="ApplicationCommands.Copy" CommandTarget="{Binding ElementName=vpRadGridView}"/>

GridColumns
1.

<telerik:GridViewDataColumn

Header="Verification Path Pair"

UniqueName="VerificationPathPair"

DataMemberBinding="{Binding Path=., Converter={StaticResource VPPair}}"

/>

2.

<

telerik:GridViewDataColumn

Header="Verification Path ID"

UniqueName="VerificationPathID"

DataMemberBinding="{Binding Name, ValidatesOnExceptions=True, Mode=OneWay, ValidatesOnDataErrors=True}"

/>

Copy Results:

MySolution.OrmNhib.BusinessObjects.OnepValidochpath

VP1

It should have copied actual data for column 1 also as it did for column 2. Any suggestion?

Error using OrientedGroupHeaderContentTemplateSelector after upgrading to WPF Q1 2011 SP1 controls

I get the following error in my code after upgrading the controls. The problem is, even the demo of group header still uses the OrientedGroupHeaderContentTemplateSelector object. What gives?

Error 10 'Telerik.Windows.Controls.OrientedGroupHeaderContentTemplateSelector' is obsolete: 'Please, use the StringFormat properties, the System.Windows.Controls.GroupHeaderTemplateSelector or inherit from System.Windows.Controls.ScheduleViewDataTemplateSelector instead.' C:\Users\rodneyy\Documents\MetrixDevelopment\MetrixDevelopment\Client\Metrix.UI\Managers\RepairCenterComponent\RepairBoardManager.cs 62 148 Metrix.UI

This is the line that produces the error...

repairBoardScheduleView.GroupHeaderContentTemplateSelector = Application.Current.FindResource("GroupHeaderContentTemplateSelector") as OrientedGroupHeaderContentTemplateSelector;

So apparently this works but I don't understand why I am casting this resource to something that it is not....

repairBoardScheduleView.GroupHeaderContentTemplateSelector = Application.Current.FindResource("GroupHeaderContentTemplateSelector") as ScheduleViewDataTemplateSelector;

RadPaneGroup's SelectedItemRemoveBehaviour is not working as expected?

Hello there,

I have an issue with SelectedItemRemoveBehaviour of RadPaneGroup - it is either not working as expected or I don't understand what is expected. I am using it to control which document is selected when the current one has been closed. It doesn't matter which value I use, everytime the first item (left to right) is selected.

Can you help me understand this property, please? Is there a bug, or I am missing something. Let me know if you need me to provide you with a basic project with this issue reproduced.

As a side note - I am adding dynamically items to RadPaneGroup of type RadDocumentPane. I would like when a user closes the current document, then the previous used one is selected. I know how to achieve this programatically, but I found this property and I thought I can use it.

Thanks for your assistance.

Best Regards,

Ivan.

Slow down when maximizing or minimizing

When i set the properties MajorTickLength and MinorTickLength, at TimeLineViewDefinition, to 1day the application slows down when the control is rendered (maximizing or minimizing the window, scrolling, getting focus, ...). Reading the forum if found how to solve this problem out when scrolling (adding a container), but i haven't found a solution for the other issues.

Here it is the definition for the control:

<

telerik:RadScheduleView

x:Name="scheduleView"

AppointmentsSource="{Binding ImmovilizationModel.ImmovilizationAppointments}"

GroupDescriptionsSource="{Binding ImmovilizationModel.GroupDescriptions}">

<telerik:RadScheduleView.ViewDefinitions>

<telerik:TimelineViewDefinition>

<telerik:TimelineViewDefinition.MajorTickLength>

<telerik:FixedTickLengthProvider />

</telerik:TimelineViewDefinition.MajorTickLength>

<telerik:TimelineViewDefinition.MinorTickLength>

<telerik:FixedTickLengthProvider />

</telerik:TimelineViewDefinition.MinorTickLength>

</telerik:TimelineViewDefinition>

</telerik:RadScheduleView.ViewDefinitions>

</telerik:RadScheduleView>

¿Is there anything i can do to speed up control rendering?

Custom labels AxisX

Hello,

I have a problem,
How we can use personal convertors on labels on AxisX?

For instance :
data(int) :3600,7200,10800
label(string) :1h,2h,3h

We need to use integers in our datas but labels need to be custom strings.

Best regards,

EditableTemplate Mask with Autocomplete

Hello Support-Team,

i'd like to customize the RadComboBox to have a masked input with autocompletion.

 <telerik:RadComboBox x:Name="maskedComboBox"                      
 ItemsSource="{Binding Path=ValuesViewModel.ExistingValues}"
 DisplayMemberPath="ValueName" SelectedValuePath="ValueId"
 SelectedValue="{Binding Path=ValuesViewModel.SelectedValue, UpdateSourceTrigger=PropertyChanged}"
 CanAutocompleteSelectItems="True" IsFilteringEnabled="True" TextSearchMode="StartsWith"
 OpenDropDownOnFocus="True" IsEditable="True"
 EditableTemplate="{DynamicResource MaskedComboBoxEditableTemplate}" />

As far as I've read the only way to reach that is to customize the EditableTemplate,
so I used Blend to get me a copy to work on.
At first I exchanged the original PickerTextBox PART_EditableTextBox simply with a
RadMaskedTextBox, which of course didn't work out the way I wanted.
So I unsuccessfully tried to find a nice example, in which someone needed the same or a similar customization.

Because of that I decided to leave the PickerTextBox the way it is and just show a MaskedTextBox instead of
the PickerTextBox and bind the MaskedTextBox.Value-property to the PickerTextBox.Text-property.
That at least worked for the filtering, but I lost theOpenDropDownOnFocus, most likely because I need the
focus on the PickerTextBox.

Code snippet of PART_EditableTextBox:

<telerik:PickerTextBox x:Name="PART_EditableTextBox"

BorderThickness="{TemplateBinding BorderThickness}"

Background="{TemplateBinding Background}"

Grid.Column=

"0"Visibility="Collapsed"

HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"

IsReadOnly="{TemplateBinding IsReadOnly}"

Padding="{TemplateBinding Padding}"

VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"

Text="{Binding ElementName=maskedTextBox, Path=Value, Mode=TwoWay}" >

<telerik:StyleManager.Theme>

<telerik:Office_BlackTheme/>

</telerik:StyleManager.Theme>

</telerik:PickerTextBox>

<Controls:RadMaskedTextBox x:Name="maskedTextBox"

Grid.Column="0"

Mask="{Binding Path=SizeChartViewModel.SizeChartMask.Mask}"

MaskType="Standard"

SelectionOnFocus="CaretToBeginning"

BorderThickness="{TemplateBinding BorderThickness}"

Background="{TemplateBinding Background}"

HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"

IsReadOnly="{TemplateBinding IsReadOnly}" Padding="{TemplateBinding Padding}"

VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}">

<telerik:StyleManager.Theme>

<telerik:Office_BlackTheme/>

</telerik:StyleManager.Theme>

</Controls:RadMaskedTextBox>

Is there any better approach to customize the ComboBox to get what I need?
Or is there any workaround to get my changes of the EditableTemplate to work the way I want it to?

Thank you!
