[Solved] Maintain selected value of RadCombox

Hi guys,

I am try my best to make myself clear. I have two pages with one of them being Config page. In the config page, I have a RadCombox to choose a time span value. The code snippets are below.

<telerik:RadComboBox Width="125" FontSize="{DynamicResource FontSizeBig}"

VerticalAlignment="Center" Height="32" Margin="0,0,5,0" SelectedValue=

"{Binding Realtime.TimeRemaining, Converter={StaticResource DetectionDurationConverter}, Source={StaticResource Locator}}"

>

<telerik:RadComboBoxItem Content="10 s" />

<telerik:RadComboBoxItem Content="10 minutes"/>

<telerik:RadComboBoxItem Content="1 hour"/>

<telerik:RadComboBoxItem Content="Custom" Margin="0"/>

</telerik:RadComboBox>

As you can see from the above code, I binds the selected value to TimeRemaing property and I would use a customized converter named DetectionDurationConverter to turn 10 s, 10 minutes and 1 hour into a time span value in C#. Here is my converter.

public class DetectionDurationConverter : IValueConverter

{

private static readonly string[] durationSet = new[] {"10 s", "10 minutes", "1 hour"};

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

{

var timeSpan = (TimeSpan) value;

if (timeSpan == TimeSpan.FromSeconds(10.0))

{

return durationSet[0];

} else if (timeSpan == TimeSpan.FromMinutes(10.0))

{

return durationSet[1];

} else if (timeSpan == TimeSpan.FromHours(1.0))

{

return durationSet[2];

}

return string.Empty;

}

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)

{

var timeSpan = TimeSpan.MinValue;

if (value is RadComboBoxItem)

{

var val = System.Convert.ToString((value as RadComboBoxItem).Content);

if (val == durationSet[0])

{

timeSpan = TimeSpan.FromSeconds(10.0);

}

else if (val == durationSet[1])

{

timeSpan = TimeSpan.FromMinutes(10.0);

}

else if (val == durationSet[2])

{

timeSpan = TimeSpan.FromHours(1.0);

}

return timeSpan;

}

For example, when I select a '10 s', it goes to ConvertBack method as expected and TimeRemaining is a 10 second time span value. Then I switched to another page and switched back, it goes to Convert method with TimeRemaining being 10 seonds still. Note, the method Convert would be entered twice. However, in the UI, no items have been selected. I just hope the selected item would be consistent with the value of TimeRemaining.

Thanks,
-J

[Solved] Case-Insensitive SpellChecking

How do I tell the SpellChecker to do a case-insentitive word comparison?

So if my dictionary of valid words contains "Foo" how do I tell the SpellChecker not to underline lower-case "foo"?

(I don't mean DocumentSpellChecker.Settings.SpellCheckUppercaseWords feature)

[Solved] Listbox: last position index is 0

Hello,

I have a RadListBox with 10 items in it, when I drag and drop them to re-order everything is working correctly except when I drop in the very last position.

I expect to get position 10 from DragDropState state.InsertIndex, however, I get position 0 and my item will get added to the top of the list.

Thank,

Kevin

Minimize the outlook bar

I guess I am missing something on the outlook bar. I have the outlook bar in a grid with horizontal and vertical size set to stretch. When I resize the form, the outlook bar resizes, great. However, when I do a minimize with either the header icon or with the right side sizer, the outlook bar doesn't move to the left, it "pinches" together in the center of the column. I know that you can have the bar collapse to the left, one of the demos show it, but I can't figure it out. How can I collapse the outlook bar to the left?

Thanks.

[Solved] Possible bug when binding to RadTimeline's PeriodStart, PeriodEnd

I want to bind the properties PeriodStart, PeriodEnd, VisiblePeriodStart, and VisiblePeriodEnd to my ViewModel, but it doesn't work like expected. Could this be a bug in the RadTimeline control?

My ViewModel class is called ParentViewModel:

public class ParentViewModel : ViewModelBase

{

public String Name { get; set; }

//public DateTime Start { get { return ChildItems.Min(x => x.Start); } }

//public DateTime End { get { return ChildItems.Max(x => x.End); } }

public DateTime Start { get { return DateTime.Now; } }

public DateTime End { get { return DateTime.Now.AddDays(7.0); } }

public TimeSpan Duration { get { return End - Start; } }

public ObservableCollection<TestViewModel> ChildItems { get; private set; }

public ParentViewModel()

{

ChildItems = new ObservableCollection<TestViewModel>();

}

public void AddChilds(IEnumerable<TestViewModel> childs)

{

foreach (var x in childs)

{

ChildItems.Add(x);

}

public void FirePropertysChanged()

{

OnPropertyChanged("Start");

OnPropertyChanged("End");

}

I set an instance of this class as the DataContext of a RadTimeline, and bind the PeriodStart and PeriodEnd properties like this:

<Grid x:Name="LayoutRoot">

<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>

<RowDefinition Height="Auto" />

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<StackPanel Orientation="Horizontal" Margin="2">

<TextBlock FontWeight="Bold" Text="PeriodStart: " />

<TextBlock Text="{Binding Start}"/>

</StackPanel>

<StackPanel Orientation="Horizontal" Grid.Row="1" Margin="2">

<TextBlock FontWeight="Bold" Text="PeriodEnd: " />

<TextBlock Text="{Binding End}"/>

</StackPanel>

<telerik:RadTimeline x:Name="radTimeline1" Grid.Row="2"

PeriodStart="{Binding Start}"

PeriodEnd="{Binding End}"

StartPath="Start"

DurationPath="Duration"

ItemsSource="{Binding ChildItems}">

<telerik:RadTimeline.Intervals>

<telerik:MonthInterval />

<telerik:WeekInterval />

<telerik:DayInterval />

<telerik:HourInterval />

<telerik:MinuteInterval />

</telerik:RadTimeline.Intervals>

</telerik:RadTimeline>

</Grid>

The Start and End properties are correctly bound to the TextBlocks and the Dates are displayed.
However, the RadTimeline's content is blank.
I tried to raise the OnPropertyChanged events (in the method FirePropertysChanged in my ViewModel), but that doesn't help.
When the date values are hardcoded in XAML, the RadTimeline works. But it doesn't work if bound to a ViewModel.
Could this be a bug?

Using the RadMap with a with tiles in a database

I'm getting back to a project I started some time ago. I'm generating map tiles with TileMill and placing the tiles in a Postgres database for use in an offline application. Is there any documentation or code sample that shows how to use a database for the RadMap data source? The first solution that comes to mind is hosting a local service that fetches the map tiles from the database. This seems like an overly complicated solution and there should be an easier way.

Thanks,

[Solved] Support for enum Intellisense and complex types?

Hi - I'm hoping to use the combo of the RadPropertyGrid with the Dynamic Linq library and generic types as a way to support business rules. I've already got fully working code with a TextBox and now am hoping to replace that with a more feature-rich ExpressionEditor.

The idea is this: given an arbitrary class (well known at runtime), create an object of the class and wire it up to the RadPropertyGrid as a "sample". Then use the RadExpressionEditor (also wired to the same object) to enable the user to craft an expression that can select that item later during some other business processing (again, I have this basically working).

My three questions are as follows:
* the RadPropertyGrid supports DataAnnotations for things like [Browsable(false)] to suppress a given property from the RadPropertyGrid. I'm wondering if the same DataAnnotation support could be added to the ExpressionEditor Fields list so that fields like "IsChanged" (just part of the IChangeTracking interface) could be suppressed.
* Can the Fields list of the ExpressionEditor be updated to support complex types like the Property Grid (like nested properties)? (e.g. Class a has three string properties and a fourth property of "ClassB" with three int properties -- I want to see the deep property names for the three ints in the field list).
* Can the Editor itself support intellisense for an enum type? (e.g. property X if of type Choices which is an enum -- so then I add "X = " using the Expression Editor functions and manually start typing "Choices." in the editor and can see the possible values.

I'm guessing the information I've provided above is enough to answer, but if you would like some code snippets and/or screenshots of this, I can provide those.

Thanks in advance for your consideration. (and congrats on the Progress thing :) )
