Hi,
How to make the RadWindow flash in taskbar?
One of the popular chatting programms does that - when you get a message, it's taskbar representation turns blue. Is it possible to do the same with a RadWindow?
What I've tried so far:
first I've made the window to appear in the taskbar by adding this to xaml:
navigation:RadWindowInteropHelper.ShowInTaskbar="True"

Next i tried googling how to do that for a regular wpf window and found something like this:
http://www.jarloo.com/flashing-a-wpf-window/
this compiles nicely but doesnt work in my case even for a wpf window. However, if i use it for a radwindow by using something like this:

public static void FlashWindow(RadWindow control)
        {
            var window = control.ParentOfType<Window>();
            window.FlashWindow();
        }
I get a null pointer exception. (there is no null pointer for regular window, but it doesnt seem to be flashing either)

Anyway, I don't really mind the method, I would just like to be able to make the taskbar window flash (system flash or manual changing of the background color on the taskbar if there is such an option?)
Is it possible with a RadWindow and if so - how to do it?
Thanks.

CUIT is not able to access the control placed inside the cell template for RadTreeListView

Hi Team,

We are using cell templates for the cells inside the RadTreeListView. In .Net 4.5 and with latest telerik package CUIT is not able to navigate to the controls placed inside the cell template where as in .Net 4.0 we were able to automate actions on it using CUIT.

Following is the sample xaml file code:

<Window x:Class="MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="clr-namespace:WpfApplication1"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Height="350" Width="525" Title="InterWalmartGraph Cafeteria Grocery Store">

<Window.Resources>

<DataTemplate x:Key="ReadonlyTextCellTemplate">

<DockPanel Margin="1">

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

<Button Content="{Binding Name}" />

</DockPanel>

</DataTemplate>

</Window.Resources>

<Grid x:Name="LayoutRoot" >

<telerik:RadTreeListView x:Name="radTreeListView"

AutoGenerateColumns="False">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" />

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"

Header="Name" />

<telerik:GridViewDataColumn Header="Count" CellTemplate="{StaticResource ReadonlyTextCellTemplate}" />

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

</Grid>

</Window>

Regards,
Sirisha

How to add thumb on radTimeLine control

Hi,

I have one application in which I am showing data availability by date wise on Rad Timeline but I am using .Net Framework Version 3.5 controls. I want add the thumb in it. I tried to explore Rad Timeline but could not able to add thumb on it. Actually when timeline is zoomed in then it is very difficult to check all dates by scrolling through scroll bar so I want to add thumb in it so user can easily scroll the timeline using mouse and dragging it in left-right either direction like scrolling through mail on smartphone. How to achieve this behavior with .Net Framework 3.5 Rad Timeline Control.

Need Collapsed Items to Vertically Align to Top

Hello!

I have noticed that when I have only one of my items expanded and the rest of them collapsed in my radpanelbar, the collapsed items all group/align at the bottom which creates a great deal of empty space between them and the expanded item (see screenshot). I was wondering if there was any way to align them upwards instead, so that they would start right after the expanded item? I have tried the following but it seems that setting

<Setter Property="VerticalAlignment" Value="Top"/>

in the style for the menu item does not help.

All the styling code is here:

<Style TargetType="telerik:RadPanelBarItem" x:Key="LeftMenuSubItemStyle">

<Style.Triggers>

<Trigger Property="IsEnabled" Value="False">

<Setter Property="FontWeight" Value="Normal"/>

<Setter Property="Opacity" Value="0.70"/>

</Trigger>

<Trigger Property="IsSelected" Value="True">

<Setter Property="FontWeight" Value="Bold"/>

</Trigger>

</Style.Triggers>

<Setter Property="IsSelected" Value="{Binding IsCurrent, Mode=TwoWay}" />

<Setter Property="IsEnabled" Value="{Binding IsNavigationEnabled, Mode=TwoWay}" />

</Style>

<Style TargetType="telerik:RadPanelBarItem" x:Key="LeftMenuMainItemStyle">

<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />

<Setter Property="VerticalAlignment" Value="Top"/>

</Style>

<HierarchicalDataTemplate DataType="{x:Type domain:DescriptiveSubMenuItem}">

<Grid Margin="15,0,0,0">

<TextBlock Text="{Binding Title}" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" TextWrapping="Wrap" FontSize="12">

<TextBlock.InputBindings>

<MouseBinding MouseAction="LeftClick" Command=

"{ Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.MenuItemClicked}"

CommandParameter="{Binding Title}" />

</TextBlock.InputBindings>

</TextBlock>

<Rectangle HorizontalAlignment="Right" Width="15" Height="15" Visibility="{Binding IsCheckVisible}" Fill="{StaticResource CompleteCheck}" Margin="0,0,10,0">

<Rectangle.InputBindings>

<MouseBinding MouseAction="LeftClick" Command=

"{ Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.MenuItemClicked}"

CommandParameter="{Binding Title}" />

</Rectangle.InputBindings>

</Rectangle>

</Grid>

</HierarchicalDataTemplate>

<HierarchicalDataTemplate DataType="{x:Type domain:DescriptiveMenuItem}" ItemsSource="{Binding SubMenuItems}" ItemContainerStyle="{StaticResource LeftMenuSubItemStyle}">

<Label Content="{Binding Header}" FontSize="16" Margin="0"/>

</HierarchicalDataTemplate>

</UserControl.Resources>

<Grid>

<telerik:RadPanelBar ItemsSource="{Binding ActiveNavigationItems}" ExpandMode="Multiple" ItemContainerStyle="{StaticResource LeftMenuMainItemStyle}">

</telerik:RadPanelBar>

</Grid>

Any suggestions would be greatly appreciated!

RadSplitButton: How to get the Key pressen when DropDownClosed

I'm using a WPF RadSplitButton and I'd like to to some special handling, when the DropDownClosed happens:

If the User presses ESC to close the dropped down content of my RadSplitButton, I'd like to do some undo operations. How do I get the Key that has caused the RadSplitBotton to close it's DropDown section?

In the Event Handler

private void RadSplitButton_DropDownClosed(object sender, RoutedEventArgs e)
{}

there is only RoutedEventArgs, which does not contain the pressed Button.

No ElementExporting when exporting to Excel via RadSpreadsheet

Hi there,

we have a converter in place hooked up to the ElementExporting event so our CSV export is properly converted.

Using the XlsxFormatProvider and RadSpreadsheet doesn't trigger that event to be fired so our Excel files are not converted.
How can exported values be customized in the RadSpreadsheet context?

Can we somehow use the Html exported by the RadSpreadsheet ?

Cheers,
Jay

Is RadTreeMap Still Supported?

I can't for the life of me get anything to show up in either the designer or at runtime. It's just blank, as if the control is not there. I'm using 2014.1.224.45 with implicit themes.

Change FontSize of property name in RadPropertyGrid

Hello.

How can I change size of font of names of properties in RadPropertyGrid? I have AutoGeneratePropertyDefinitions="True", so everything generates automatic. Furthermore I would like to do it in xaml file if it is possible.

I have just tried to set FontSize for the RadPropertyGrid and it didn't work. Moreover I think there is different sizes for different text fields in RadPropertyGrid.

I have attached a picture of what I am talking about.

Thank you for help,
Ilya.

Grouping now working when exporting to Excel

Hi there,

We're trying to get grouped RadGridView content exported but neither the CSV Export (either via Export() or ToCsv()) nor Excel Export via RadSpreadSheet and XlsxFormatProvider is giving us the grouping we have in the UI.

Specifically we're missing the group headers we can see in the UI -
With the appropriate flag we can have the group footers in the CSV.. but that's not giving us the headings we're looking for (the ones that can be seen in the UI).

How can we export the current grouping to CSV and Excel whilst preserving the grouping headers?

Thanks,
Jay
