Hi,

I have bar chart with  Y-Axis having range from 0 to 100. On the same chartarea I have one more Y-Axis(right hand side) having range from -100 to 100 in the step of 50. i want to make -100, -50 label values invisible so that 0 starts in the middle of the Y-axis.  I am using this Y-Axis for showing line chart. Please help me achieve this.

In the treelistview row loaded event , when I am trying to expand a tree node programatically,the scrollviewer resets.

 

private void rtSummaryInfo_RowLoaded(object sender, RowLoadedEventArgs e)

 

{    

 

        TreeListViewRow

 

lobjTreeListViewRow = (e.Row as Telerik.Windows.Controls.TreeListView.TreeListViewRow);

 

 

        SummaryData lobjSummaryData = (e.Row as Telerik.Windows.Controls.TreeListView.TreeListViewRow).DataContext as SummaryData;

 

 

        if (_lstExpandedNode.Contains(lobjSummaryData.NodeName))

 

        {

     

 

          lobjTreeListViewRow.IsExpanded =

true;  // at this point, scrollviewer gets resets 

 

        }

}

I need to maintain the scroll position while expanding a node. Your help is appreciated.

Hello,
I would like to implement in my WPF application autoupdate functionality, like WPF online demos. Is it using click once??
My application will be separated in modules, and I want to each module check for newest version, download and install it automatically.
The application is goning to run in our intranet, not internet like demos.
I was seeing demos source but it's a bit complicated, I would like to see a simplest example.

Thanks in advance
Alejandro

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 = "";

<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

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}">

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

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

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

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!
