We have a grid with several properties. Length of each "Display name" is different: there are short names like "Step" and long names like "Upper alignment style". I want the "Display name" column (property name column) to auto-size according to the longest property name in the grid.
Currently I tried two options:
1. specify LabelColumnWidth to Auto, but this gives row-based auto-sizing, but I want that that all rows have the same width (looks like a single column)
2. not specify anything, the width is set to ~200px that's too long for me

Can you please suggest a proper way to have auto-sized width for the whole column?

Thank you!

Tile width do not expand to 100%

Hi,

I wonder why this code fails to produce tiles that occupy the full width of the TileView:

<telerik:RadTileView DockPanel.Dock="Top" ItemsSource="{Binding Phases}" ScrollViewer.HorizontalScrollBarVisibility="Disabled"

SelectionMode="Single" ColumnWidth="*" ColumnsCount="1" IsAutoScrollingEnabled="True"

IsSynchronizedWithCurrentItem="True" IsSelectionEnabled="True"

MaximizeMode="Zero" RowHeight="Auto"

telerik:TileViewPanel.IsRowsShrinkEnabled="True"

telerik:StyleManager.Theme="Expression_Dark">

<telerik:RadTileView.ContentTemplate>

<DataTemplate>

<Grid Margin="6">

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*" />

<ColumnDefinition Width="Auto" />

</Grid.ColumnDefinitions>

<ContentControl Grid.Column="0" HorizontalAlignment="Stretch" Content="{Binding}" >

<ContentControl.Style>

<Style TargetType="{x:Type ContentControl}">

<Setter Property="ContentTemplate" Value="{StaticResource PhaseTemplate}" />

<Style.Triggers>

<DataTrigger Binding="{Binding IsChecked, ElementName=EditButton}" Value="True">

<Setter Property="ContentTemplate" Value="{StaticResource PhaseEditTemplate}" />

</DataTrigger>

</Style.Triggers>

</Style>

</ContentControl.Style>

</ContentControl>

<ToggleButton x:Name="EditButton" Margin="6,0,6,0" Grid.Column="1"

Style="{StaticResource EditToggleButton}"

HorizontalAlignment="Right" VerticalAlignment="Top" />

</Grid>

</DataTemplate>

</telerik:RadTileView.ContentTemplate>

</telerik:RadTileView>

I can see, using Snoop, that the TileView takes the full width where it's shown, but when I create TileViewItems in it, they occupy a fraction of the TileView. When I create a second TileViewItem, it's displayed in the second row, though, even if there's enough space left in the first row. It's like the column width is not what I expect, but the column count is respected.

Any help will be greatly appreciated.

Regards,

Alex

BusyIndicator over ListBox has style issue

When a ListBox is "below" a RadBusyIndicator in the visual tree, it seems to have a focus
or styling issue; its color changes to a light gray or off-white. Is this a known issue or
expected behavior? Is there a work-around? Here is a sample UserControl I threw together
to demonstrate what it's doing. The first ListBox appears correctly, the second one is shaded.

<UserControl x:Class="ListBoxFocusIssueUC"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:tk="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300">

  <tk:RadBusyIndicator Grid.Row="1" Background="Transparent" BusyContent="Testing..." IsBusy="true">
   <ListBox BorderThickness="0" MaxHeight="80">
    <ListBox.Items>
     <ListBoxItem Content="Item #1" />
     <ListBoxItem Content="Item #2" />
     <ListBoxItem Content="Item #3" />
    </ListBox.Items>
   </ListBox>
  </tk:RadBusyIndicator>
</Grid>
</UserControl>

GridViewComboBoxColum with IsComboBoxEditable="true" never sets value

I have the following column in a grid:

<t:GridViewComboBoxColumn IsComboBoxEditable="True"

DataMemberBinding="{Binding Path=QuoteNum, Mode=TwoWay}"

Header="Quote" Width="125"

ItemsSource="{Binding Path=AvailableQuotes, Mode=OneWay}" />



The ItemsSource is a simple IEnumerable<string>, and the combo shows the values from the ItemsSource, but I also want to allow the user to input a value that is not in the list (ItemsSource), hence the IsComboBoxEditable="True".



However, whenever you type in a value to the combobox, the value is lost and the column is left unset.  In fact, as far as I can tell the property setter on the view model is never actually called.



What am I doing wrong?

Frozen / Pinned Rows

Hello,

I am looking to add frozen / pinned row functionality to our grids, just like Excel. I've already found this blog post and modified it for WPF.

http://blogs.telerik.com/blogs/posts/10-07-05/frozen-pinned-rows-in-radgridview-for-silverlight.aspx

There are still a few items which I am struggling with. The first, which is quite major, is that the sample simply uses auto generated columns. That will not work for me, I need to specify the columns. Our columns are defined in XAML and can be quite complex, with DataTemplates and a number of styling options configured. I don't want to define those again somewhere, and even if I do I'm not sure how I would access them. I simply want the columns that are already in the grid to appear in the frozen container as well.

The second item, is that the Column Headers are not appearing, not sure why.
