Is it possible to change the localization dynamically, while the application is running ?
I tried this:

public CultureInfo UICulture
        {
            get
            {
                return Thread.CurrentThread.CurrentUICulture;
            }
            set
            {
                if (value == null)
                {
                    throw new ArgumentNullException("value");
                }

                Thread.CurrentThread.CurrentUICulture = value;

                if ( Telerik.Windows.Controls.LocalizationManager.Manager != null )
                {
                    Telerik.Windows.Controls.LocalizationManager.Manager.Culture = value;
                }

                UpdateLocalizations();
            }
        }

This doesn't seem to work. The culture that I'm passing is fr-FR, and it seems you support the French language. What am I missing ?

Thanks,
Sebastien

From a list of folders populate a treeview question...

In our database, we have a huge list of files in a table that we would like to show on a treeview. The thing is that the field that contains the info is saved in a string in the following format:

c:\rootfolder\2011\03\10\folder\file.docx
c:\rootfolder\2011\02\11\folder\another.docx
c:\rootfolder\2011\03\10\folder\thisfile.docx

They are all saved in an object List<Item> that contains a property whose name is Object.FullPath

I was wondering if the wpf radtreeview has already built-in on the control where you pass the info and automatically parses the content.

Any thoughts?

RadGrid is Sqeezing when populated large data.

Hi All,

I am working on WPF 4.0 and using telerik grid in it.

The following Style i have applied for the Radgridview in my application.

<Style TargetType="telerik:GridViewHeaderCell">

<Setter Property="Background" Value="{StaticResource MainHeaderColor}"/>

<Setter Property="BorderBrush" Value="#D4D6D6"/>

<Setter Property="BorderThickness" Value="1"/>

<Setter Property="VerticalContentAlignment" Value="Center" />

<Setter Property="HorizontalContentAlignment" Value="Center" />

</Style>

<Style x:Key="GridViewHeaderRowStyle" TargetType="{x:Type telerik:GridViewHeaderRow}">

<Setter Property="Background" Value="White"/>

<Setter Property="BorderBrush" Value="#D4D6D6"/>

</Style>

<Style x:Key="AlternateRowStyle" TargetType="{x:Type telerikGridView:GridViewRow}">

<Setter Property="Background" Value="#E3F0F9" />

<Setter Property="BorderBrush" Value="#D4D6D6" />

</Style>

<Style x:Key="GridViewRowStyle" TargetType="{x:Type telerikGridView:GridViewRow}">

<Setter Property="Background" Value="White" />

<Setter Property="BorderBrush" Value="#D4D6D6" />

</Style>

<Style x:Key="DataCellsPresenter" TargetType="{x:Type telerik:GridViewHeaderRow}">

<Setter Property="Background" Value="{StaticResource MainBackgroundColor}" />

<Setter Property="BorderBrush" Value="#D4D6D6" />

</Style>

<DataTemplate x:Key="GridViewHeaderIndentCellDataTemplate">

<telerik:GridViewHeaderIndentCell BorderBrush="#D4D6D6"/>

</DataTemplate>

<DataTemplate x:Key="GridViewHeaderIndicatorPresenterTemplate">

<telerik:IndicatorPresenter x:Name="PART_IndicatorPresenter"

Background="{StaticResource MainBackgroundColor}"

BorderBrush="{StaticResource SeperatorColor}"

BorderThickness="1"

Grid.Column="0" HorizontalAlignment="Left"

Width="24"/>

</DataTemplate>

<Style TargetType="{x:Type telerik:RadGridView}">

<Setter Property="HeaderRowStyle" Value="{DynamicResource GridViewHeaderRowStyle}"/>

<Setter Property="AlternateRowStyle" Value="{DynamicResource AlternateRowStyle}"/>

<Setter Property="IsFilteringAllowed" Value="false"/>

<Setter Property="RowStyle" Value="{DynamicResource GridViewRowStyle}"/>

<Setter Property="GridLinesVisibility" Value="Both"/>

<Setter Property="Cursor" Value="Hand"/>

<Setter Property="Background" Value="White" />

<Setter Property="VerticalGridLinesBrush" Value="#D4D6D6"/>

<Setter Property="HorizontalGridLinesBrush" Value="#D4D6D6"/>

<Setter Property="RowIndicatorVisibility" Value="Collapsed"/>

<Setter Property="AlternationCount" Value="2"/>

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

<Setter Property="HorizontalAlignment" Value="Center"/>

<Setter Property="ShowGroupPanel" Value="False"/>

<Setter Property="AutoGenerateColumns" Value="False"/>

<Setter Property="IsReadOnly" Value="True"/>

<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>

<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>

<Setter Property="IsScrolling" Value="false"/>

<Setter Property="Margin" Value="0,0,0,0"/>

</Style>

Now when I am using this Radgrid in my application and opening the screen then at that time the grid first squeeze and then open up in the screen withits full width.In some screens its also giving a jerking effect and then opening properly.

Kindly let me know why is it happening so ?

Thanks in advance !!!!!!

Can't type comma in filter-popup

I have a RadGridView where one of the columns is of type decimal. I want to be able to filter that by decimal numbers, but it's impossible to type commas in the textboxes in the filtering popup.

The filtering itself works fine. I've tried to apply a filter with a decimal (0.5) with code and it works: the correct rows are displayed and the rest are hidden. But when I did this the textbox in the popup displayed '0' and not '0.5'.

Why is this and is there any way around this? Is it a bug or is it by design? Hopefully it is not by design because that would render the filtering useless in my case since all my numbers are less than 1...
