Hide the Match Case button in the filter popup?

There is sample code in the docs for hiding the match case button here:
http://www.telerik.com/help/silverlight/gridview-how-to-hide-match-case.html

It appears to be out of date as this code does not build. I get the following error:
Cannot apply indexing with [] to an expression of type 'System.Collections.Generic.IEnumerable<System.Windows.Controls.Primitives.ToggleButton>'

For this line of code in the docs:

 ((StringFilterEditor) sender).ChildrenOfType<ToggleButton>()[0].Visibility = Visibility.Collapsed;

Any ideas how to accomplish this with the latest build of the gridview control?

WPF: Validating SelectedItem on RadComboBox at the very beginning

Hi,

I am trying to setup a form that will validate whether a combo box (as well as other inputs) is filled or not. It seems that the Binding of RadComboBox only happens after PropertyChanged or LostFocus. What if the input hasn't been touched by the user at all - hence the binding couldn't be triggered?

I can't seems to get it to work. Please help.

Cheers~

Default theme styles

Hello! Is there way to get default font family from theme for controls like Label, TextBlock etc?

Maybe you have predefined styles for Header/Outline/Simple text controls(Font family, size, color)?

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.

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

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?
