QR-Code

Hi,

I visited your Q3 2011 features site and I'm happy to see that barcode will be included in your tool set soon. Nonetheless, I am disappointed to see that 2-d codes especially QR-code is not included. I really hope that the support for QR-code will be included in the release.

Can you share the roadmap for barcode tool? Thanks.

[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
