[Solved] Editor UI Bug - spacing doesn't drop a line

Hi,

Is there a bug with the latest version of RadRichTextBox UI (2012.3.1017.4) where blank spaces at the end of a page continue to follow the same line rather than drop to the line beneath?

This behaviour is not experienced when typing text, only blank spaces using the space bar.

Please see my attached screenshots for a better example of what I'm referring to.

Thanks,

Rob

[Solved] VisiblePeriodStart Not Set

Hello! Using Q1 2012.

I'm trying to set default values for the period bindings and am having some difficulty with VisiblePeriodStart. This guy just doesn't want to get set even though they are in the right order and two-way bound. Suggestions?

View:

<telerik:RadTimeBar Height="150" Margin="40,20,40,40" telerik:StyleManager.Theme="Windows7"

PeriodStart="{Binding PeriodStart, Mode=TwoWay}"

PeriodEnd="{Binding PeriodEnd, Mode=TwoWay}"

VisiblePeriodStart="{Binding VisibleStart, Mode=TwoWay}"

VisiblePeriodEnd="{Binding VisibleEnd, Mode=TwoWay}"

SelectionStart="{Binding SelectionStart, Mode=TwoWay}"

SelectionEnd="{Binding SelectionEnd, Mode=TwoWay}"

>

<telerik:RadTimeBar.Intervals>

<telerik:YearInterval />

<telerik:MonthInterval />

<telerik:DayInterval />

</telerik:RadTimeBar.Intervals>

<telerik:RadAreaSparkline ItemsSource="{Binding TimeBarData}" XValuePath="Date" YValuePath="Total" telerik:StyleManager.Theme="Windows7" AutoRange="False" />

</telerik:RadTimeBar>

ViewModel:

public class ViewModel

{

public ObservableCollection<DetailTimeBarModel> TimeBarData { get; private set; }

public DateTime PeriodStart { get; set; }

public DateTime PeriodEnd { get; set; }

public DateTime VisibleStart { get; set; }

public DateTime VisibleEnd { get; set; }

public DateTime SelectionStart { get; set; }

public DateTime SelectionEnd { get; set; }

public ViewModel()

{

TimeBarData = new ObservableCollection<DetailTimeBarModel>

{

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-20), Total = 5},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-18), Total = 1},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-16), Total = 3},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-14), Total = 7},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-12), Total = 6},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-10), Total = 3},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-8), Total = 12},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-6), Total = 6},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-4), Total = 3},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(-2), Total = 3},

new DetailTimeBarModel {Date = DateTime.Now.AddDays(0), Total = 2}

};

PeriodStart = TimeBarData.Min(x => x.Date);

PeriodEnd = TimeBarData.Max(x => x.Date);

VisibleStart = PeriodEnd.AddDays(-10);

VisibleEnd = PeriodEnd;

SelectionStart = PeriodEnd.AddDays(-2);

SelectionEnd = PeriodEnd;

}

public class DetailTimeBarModel

{

public DateTime Date { get; set; }

public int Total { get; set; }

}

Remove selection border

Hello,

I'm using an instance of RadListBox with Windows7 theme.

By default, a thin blue border appears around the selected listbox item - which I do not want. Rather, I would prefer to change the background color of the listbox item when it is selected.

How can I achieve this?

[Solved] SelectedItem binding not working

Hi,

I am using an AutoCompleteBox inside a RadDataForm template.The control ItemsSource is bound to an ObseravableCollcetion while the selected item is bound to a property on the window.

<DataTemplate x:Key="MyTemplate">

<Grid>

<Grid.RowDefinitions>

<RowDefinition/>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="200"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<Label Content="Driver" Grid.Row="0"/>

<Label Content="Document Number" Grid.Row="1"/>

<Label Content="Issue Date" Grid.Row="2"/>

<Label Content="Expiry Date" Grid.Row="3"/>

<Label Content="Place of Issue" Grid.Row="4"/>

<Label Content="Document Type" Grid.Row="5"/>

<Label Content="Remarks" Grid.Row="6"/>

<telerik:RadAutoCompleteBox AutoCompleteMode="Suggest"

TextSearchPath="FullName" ItemsSource="{Binding Drivers,ElementName=DriverDocumentView1}" Name="RadAutoCompleteBox" SearchTextChanged="RadAutoCompleteBox_SearchTextChanged" TextSearchMode="Contains" SelectionMode="Single" DisplayMemberPath="Name" SelectedItem="{Binding SelectedDriver,ElementName=DriverDocumentView1}" Grid.Column="1" Grid.Row="0"/>

<TextBox Text="{Binding Document.DocumentNo}" Grid.Row="1" Grid.Column="1"/>

<DatePicker SelectedDate="{Binding IssueDate}" Grid.Row="2" Grid.Column="1"/>

<DatePicker SelectedDate="{Binding ExpiryDate}" Grid.Row="3" Grid.Column="1"/>

<ComboBox ItemsSource="{Binding PlacesOfIssue,ElementName=DriverDocumentView1}" DisplayMemberPath="Text" SelectedValuePath="ID" SelectedValue="{Binding Document.PlaceOfIssueID}" Grid.Column="1" Grid.Row="4"/>

<ComboBox ItemsSource="{Binding DocumentTypes,ElementName=DriverDocumentView1}" DisplayMemberPath="Name" SelectedValuePath="ID" SelectedValue="{Binding Document.DocumentTypeID}" Grid.Column="1" Grid.Row="5"/>

<TextBox Text="{Binding Remarks}" Grid.Row="6" Grid.Column="1"/>

</Grid>

</DataTemplate>

private Driver selectedDriver;

public Driver SelectedDriver

{

get { return selectedDriver; }

set { selectedDriver = value; NotifyPropertyChanged("SelectedDriver"); }

}

Now, the breakpoint I set in the 'set' part of the SelectedDriver property is not hit.I also find it to be null when sending the form data for saving:

private void SaveBTN_Click(object sender, RoutedEventArgs e)

{

if (RadDataForm.ValidateItem())

{

DriverDocument driverDocument = RadDataForm.CurrentItem.To<DriverDocument>();

driverDocument.Document.CreationDate = DateTime.Now;

driverDocument.Document.EntryByID = 178;

driverDocument.Driver = SelectedDriver;

RadDataForm.SubmitChanges();

}

Thanks

Can RadWindow be used as a 'framed in' child window?

Is RaWindow a good candidate to function as a child window that cannot be dragged outside the confines of its parent's boundaries?

Similar to shadowbox-type functionality on websites when user input is required and parent is locked? We'd like the user to still be able to drag/resize/minimize/etc the parent while the child window is controlling it.

Custom String Range on Y Axis

hello,

i am trying to set up a custom range on my y axis as our 'date' values are custom generated and do not work in the same way as normal dates or numeric values.

we have a situation where the chart would run along variable time levels, ie sometimes weeks, sometimes months, quarters, etc. the chart needs to plot these time members across the Y axis of a horizontal 2D Bar chart and display the values as such:

M201010 M201011 M201012 M201101 etc..

what we did to overcome the fact that we need a numeric value for the axis was to use only the numeric section of the chart and then set a min and max value (since we know the start and end date for the chart) but this works only as long as the values are for the same year, in this example 2010.

if the periods span over 2 years, ie from 2010 to 2011, the series stretches from M201012 all the way to M201099 before getting on to 2011, because it increments by one of course.

the chart is set up in the xaml as follows:

<telerik:RadChart Grid.Row="0" Grid.Column="0" x:Name="TimeRangeChart" ItemsSource="{Binding PhasingOptionList}" UseDefaultLayout="False" DataBound="TimeRangeChart_Loaded">

is there a way to get around this?
