I've noticed a strange performance issue with QueryableCollectionView (which it seems is being used as the default CollectionView for the RadGridView). If I add just a single item to the list, QueryableCollectionView ends up calling PopulateListInternal, which will iterate through ALL of the items in the in my ObservableCollection. Why is this the case?

According to their documentation “Link below” to set their date time picker to military time you have to create a new culture. We are using the culture below, as you can see from the screen shot it got it half way right but I think it would be better without the AM & PM after it.I attached a screen shot of the clock. We just want to remove the AM and PM.

 

CultureInfo cultureInfo = new CultureInfo("en-US");

cultureInfo.DateTimeFormat.ShortTimePattern = "H:mm";

cultureInfo.DateTimeFormat.LongTimePattern = "H:mm";

cultureInfo.DateTimeFormat.PMDesignator = "";

cultureInfo.DateTimeFormat.AMDesignator = "";

If we set style via  

within our User Control
all is working as expected but if comment this in usercontrol out and put the same code

<Helpers:RequiredValueStyleSelector x:Key="RequiredFieldStyleSelector" />

<Style  TargetType="telerik:GridViewDataColumn">

    <Setter Property="CellStyleSelector" Value="{StaticResource RequiredFieldStyleSelector}"/>

</Style>

 

 into generic.xaml nothing happens

Any suggestions?
PS. in Helper.dll attributes look like

[assembly: ThemeInfo(

  Hi everybody
i try to change headerRow Color
but it have a little i don't know to how change. pls check the attach.

<Grid.Resources>
            <Style x:Key="style1" TargetType="telerik:GridViewHeaderRow">
                <Setter Property="Background" Value="#FFB8C8E4"/>
                <Setter Property="BorderThickness" Value="0"/>
                
            </Style>
           
            <Style x:Key="style3" TargetType="telerik:GridViewFilteringDropDown">
                <Setter Property="IsEnabled" Value="False" />
            </Style>
            
            <Style x:Key="style2" TargetType="telerik:GridViewHeaderCell">
                <Setter Property="Background" Value="#FFB8C8E4"/>
                <Setter Property="BorderThickness" Value="0"/>
                <Setter Property="Foreground" Value="Black"></Setter>
            </Style>
        </Grid.Resources>

<telerik:RadGridView  Margin="40,24,88,72" HeaderRowStyle="{StaticResource style1}" ItemsSource="{Binding Collection}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn FilteringControlStyle="{StaticResource style3}" Header="EmployeeName" HeaderCellStyle="{StaticResource style2}" DataMemberBinding="{Binding Property3}"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

There are combo boxes all over the app that are experiencing the same issue.  This combo box in particular is bound to a Dictionary which is loaded based on the current language the user has selected in their preferences of the application.  Normal text fields etc are display the correct translation from the correct resource file.  Placing a breakpoint in code shows the correct translated values in the MyTypes, however, from the UI the combo box ItemsSource are always displayed in English.

How can I get the correct translated item from the resource file to be display in the combo box?

Visual Studion 2010

public Dictionary<string, string> MyTypes

{

get { return myTypes; }

}

public void InitializeCriteria(SelectionCriteria criteria)

{

var culture = Thread.CurrentThread.CurrentUICulture.ToString();

base.InitializeStandardSelectionCriteria(criteria, culture);

// Load the Types

var mTypes = MyTypes.Select(c => new Tuple<string, string>(c.Key, c.Value));

Array.ForEach(mTypes.ToArray(), criteria.MyTypes.Add);

var defaultMyType = criteria.MyTypes.FirstOrDefault();

if (defaultMyType != null)

{

criteria.MyTypes= defaultMyType .Item1;

}

}

protected override void OnInitialize(ESEntities entities)

{

    base.OnInitialize(entities);

 

    LoadMyTypes(entities);

    LoadSomeOtherData(entities);

}

private void LoadMyTypes(ESEntities entities)

{

 myTypes = new Dictionary<string, string>()

 {

  { "" , Resources.Resources.NoneLabel },

  { "D", Resources.Resources.DMessage },

  { "F", Resources.Resources.FMessage},

  { "H", Resources.Resources.HMessage },

  { "I", Resources.Resources.IMessage },

  { "L", Resources.Resources.LMessage } };

}

 

<GroupBox x:Name="LGroup" Header="{x:Static Resources:Resources.OptionsL}">

           <telerik:RadComboBox x:Name="attenuationComboBox"

                 ToolTip="{x:Static Resources:Resources.OptionsDesired}" Height="23"

                 VerticalAlignment="Top"  ItemsSource="{Binding Criteria.MyTypes, Mode=OneWay,

                 NotifyOnSourceUpdated=True, NotifyOnTargetUpdated=True,UpdateSourceTrigger=PropertyChanged}"

                 SelectedValue="{Binding Criteria.MyType, Mode=TwoWay}"

                 IsEnabled="{Binding SelectionOptions.CEnabled}" DisplayMemberPath="Item2" SelectedValuePath="Item1" />

</GroupBox>

 

 

 

 

 

Hi,

Children rows (when expanded) don't get drawn properly after using AddRange(elementList) to add to the Children collection. Visually, exactly one row gets added to the children elements regardless of how many elements in the elementList list. They seems to get drawn properly only if I manually collapse then expand them again.

Thanks,

Vince

Hi,

I've created a custom appointment just like this tutorial demonstrates.

Everything works fine, but now I'm trying to apply a style trigger to an appointmentiotemcontenttemplate:

        <DataTemplate x:Key="AppointmentItemContentTemplate">
            <Grid>
                <Border>
                    <Border.Style>
                        <Style>
                            <Style.Triggers>
                               <DataTrigger Binding="{Binding ProductCategory}" Value="Building">
                                    <Setter Property="Border.Background" Value="CornflowerBlue"></Setter>
                                </DataTrigger>
                            </Style.Triggers>
                        </Style>
                    </Border.Style>
                    <Grid>
                        <TextBlock Margin="8,2" HorizontalAlignment="Stretch" TextWrapping="Wrap" Text="{Binding Subject}" Grid.Column="1" />
                        <TextBlock Margin="8,2" HorizontalAlignment="Stretch" TextWrapping="Wrap" Text="{Binding ProductCategory}" Grid.Column="1" />
                    </Grid>
                </Border>
            </Grid>
        </DataTemplate>

In two instances here I'm trying to use the ProductCategory property, and it won't work. If I were to change the trigger to use the 'Subject' property of the appointments I am dragging (from a listbox I should add) onto the ScheduleView it works without a problem. Likewise, the textblock that attempts to display the ProductCategory does not work, whereas the 'Subject' does. It seems that any additional fields I have added to the Job.cs (custom appointment) are not accessible!? The syntax (private/get/set) is exactly the same as the tutorial so I can't understand it?

Thanks a LOT for any help in advance!

Hi guys,

I have a quick question from you guys. Is there any property wrap the grouped columns to the next line in case the count of grouped columns increases more than the available grid area? 
Check out the screen shot attached for more clarity on my question. I have grouped even with column "Phone", but its not available in the visible grid. All I need is to make sure that column phone is visible in the grouped columns list.
Please let me know if the question is not clear.

Regards,

Hello.

How raddataform works with enums

thank's.

I'm using a RadTreeListView to display the following data (this is a mockup of the real business model):

Directory AAA
|__ SourceFile 001
                  |__ Function 001
                  |__ Function 002
|__ SourceFile 002
                  |__ Function 001
                  |__ Function 002
Directory BBB
|__ Directory BBB.1
                  |__ SourceFile 001
                                    |__ Function 001
|__ SourceFile 002
                  |__ Function 001
                  |__ Function 002

Model for these and the xaml are using are below:

So my issue is that if I leave the binding for Functions  in the XAML I get what you can see in pic 1 (issue.jpg) the third level directory entries are not expandable; if I remove that binding then I get the hierarchy working, of course up until the source file level (no_functions_binding.jpg).

Any idea what could be going on?

Thanks,
Jose
