[Solved] RadMaskedDateTimeInput control not displaying value properly

I've got a RadMaskedDateTimeInput control in my application:

<telerik:RadMaskedDateTimeInput BorderBrush="{Binding Path=BorderBrush, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

FlowDirection="{Binding Path=FlowDirection, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

Focusable="True"

FontFamily="{Binding Path=FontFamily, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

FontSize="{Binding Path=FontSize, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

FontStretch="{Binding Path=FontStretch, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

FontStyle="{Binding Path=FontStyle, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

FontWeight="{Binding Path=FontWeight, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

GotFocus="ValueBox_GotFocus"

Grid.Column="0"

FormatString="{Binding Path=Mask, Mode=OneWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

HorizontalAlignment="Stretch"

HorizontalContentAlignment="Right"

InputBehavior="Insert"

IsClearButtonVisible="False"

LostFocus="ValueBox_LostFocus"

Margin="5"

Mask="{Binding Path=Mask, Mode=OneWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

Name="ValueBox"

SelectionOnFocus="CaretToEnd"

SpinMode="PositionAndValue"

TabIndex="{Binding Path=TabIndex, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}}"

TextMode="MaskedText"

UpdateValueEvent="PropertyChanged"

Value=

"{Binding Converter={StaticResource TimeSpanConverter}, Path=Value, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type cs:TimeSpanSpinner}}, UpdateSourceTrigger=PropertyChanged}"

VerticalAlignment="Center" />

This is actually inside of a UserControl. That user control is then used in another UserControl that is used to edit user settings. The first UserControl is supposed to provide spinner functionality for specifying a time out interval on a touch screen computer. There are two big buttons next to the RadMaskedDateTimeInput control, one for increasing the value and one for decreasing it. Since the value is a time out, the data type of the variable being edited is TimeSpan, and I want to see the text formatted as HH:mm:ss.fff. That's what the Mask property is set to, and the FormatString is set to that, too.

The control displays correctly until I put the cursor in it. At that point, the HH:mm:ss.fff formatting goes away and I see 01/01/0001. This is useless. This did work properly at one time, but now it's broken and I don't know why. Why is the control ignoring the input mask???

I'm using the 2012 Q1 version of the library.

Fading out items

I've managed to get a RadTileViewItem to fade in when it's added to the TileView. That was easy of course, as the item exists, and I can just set it's opacity to 0 and move it up.

However, I also want to get an item to fade out. But, when the item is removed from the underlying collection, the RadTileViewItem is of course immediately removed, and so it's gone.

How can I accomplish this?

[Solved] Slider clip Ticks

Hi,
my problem is that the slider clips my ticks, because he think they are to long.
Set ClipToBounds to false does not help to solve this issue.

Here is my code:

<telerik:RadSlider Grid.Row="3"

Grid.Column="0"

Grid.ColumnSpan="2"

Margin="25,0,25,10"

Value="{Binding SlectedTimeSpan}"

VerticalAlignment="Bottom"

Minimum="0"

Maximum="24"

TickFrequency="8"

TickPlacement="BottomRight"

ClipToBounds="False"

IsSnapToTickEnabled="True">

<telerik:RadSlider.TickTemplate>

<DataTemplate>

<StackPanel ClipToBounds="False">

<Ellipse Width="5"

Height="5"

Fill="Black"

HorizontalAlignment="Center" />

<TextBlock Text="{Binding StringFormat=+{0} Std.}"

HorizontalAlignment="Center" />

</StackPanel>

</DataTemplate>

</telerik:RadSlider.TickTemplate>

</telerik:RadSlider>

You can find a picture of the result as attached file.

Can anybody help me with this issue???

Scroll Issue

Hello. If I set the Width property of the RadRibbonGroup, the scrolling does not go all the way over. See attached screenshots. If I remove the Width property, the scrolling works fine. I set the width because I place different controls in the group and the sizing isn't correct unless I set the size. Is there any way to get this to work?

<

telerik:RadRibbonGroup Header="Test2" Width="300">

Thanks

Disable RowsUnload for collapsed rows

Hi,

Is there a way to say to the TreeListView not to unload rows when the parent node is collapsed?

I have already set EnableColumnVirtualization="False" and EnableRowVirtualization="False"

The same question when pager is used.

Thanks,

Server side filtering with VirtualQueryableCollectionView

I got VirtualQueryableCollectionView working with RadComboBox when VirtualizingStackPanel is used.

However, when filtering is enabled, the ComboBox would load all the items (batched in LoadSize) from the VirtualQueryableCollectionView before displaying the dropdown. Am I missing something here?

The combobox Xaml:

<telerik:RadComboBox ItemsSource="{Binding Items}"

SelectedItem="{Binding SelectedItem}"

DisplayMemberPath="Name"

IsFilteringEnabled="True"

TextSearchMode="Contains"

ClearSelectionButtonVisibility="Visible"

ClearSelectionButtonContent="Remove">

<telerik:RadComboBox.ItemsPanel>

<ItemsPanelTemplate>

<VirtualizingStackPanel/>

</ItemsPanelTemplate>

</telerik:RadComboBox.ItemsPanel>

</telerik:RadComboBox>

Support for VirtualQueryableCollectionView

Is it possible to add support for VirtualQueryableCollectionView?

In the software that I am working on, the data source contains hundreds of thousands records via WCF data service (OData), and it would take forever to load if the list had to be populated fully before AutoCompleteBox can search.
