Binding RadComboBox not working when collapsed

Hi,
I have a RadComboBox that is in a RadExpander which I have bound to a public property that returns a set of key value pairs. I copied this same RadComboBox, renamed it, and placed it in a DataTemplate for a ListBox so when a User Selects the item in the ListBox the static text's visibility collapses and the editable fields are presented. I am running into the problem where the RadComboBox doesn't bind. The initial visibility of the RadComboBox is collapsed. Any Ideas?

Problem with auto sizing

I had a problem with Gauge auto sizing.
When I assign the RadGauge control of width and height in NaN (the minimal width and height equal 0, VerticalAlignment and HorizontalAlignment – Center), I receive a control of 100 x 100 no matter what container I have (Grid, StackPanel, Canvas), though I expected to see the control of 0x0 size.
Can you tell me, why it happens? How can I avoid such situation and make auto sizing work correctly?

Sort order of groupings

Hello,

I have a grouping in my grid which is specified in xaml. The grouping has two possible values, "Live" and "Paper".

I'd like to ensure that the "Live" grouping is always on top, regardless of how the user sorts data in the grid. (They cannot sort by the column I am using to group by).

How can this be accomplished?

Thanks

Hi All,

Could someone answer the question on Barcode? I know that telerik support the barcode on Reporting. But my requirement is to use the barcode in Winform. Does Telerik Barcode engine support this, if not how do I use the Barcode other than in Reporting? Looking forwards to your suggestions.

Thanks

Paging - dynamic pagesize?

I am using the Telerik gridview and the RadDataPager quite successfully. However how should you set the page size to cope with an adjustable container window size when the grid size is set to auto? The choice seems to be to set it to a low number to avoid vertical scrolling but have lots of space below the grid when the window is maximised, or accept vertical scrolling with a much large page size.
In an MVVM design, how would you set the page size according to physical grid and window sizes, also taking into account the group panel, for example, which might be shown or not? - or have I missed some existing functionality?

Thanks

Databinding with a identity column

Hi,

I have a problem in a Grid, editing a new row previously entered.

The sequence is this :

1. First I insert a new row.

The code in AddingNewDataItem Event Handler of the Grid is :

public void EUGruppoGrid_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)

{

if (e.Cancel) return;

String TipoCurrentItem;

GridViewDataControl GridViewDataControl = e.OwnerGridViewItemsControl;

if (GridViewDataControl.CurrentItem != null)

TipoCurrentItem = ((EUGruppoVO)GridViewDataControl.CurrentItem).Tipo;

else

TipoCurrentItem = " ";

e.NewObject = new EUGruppoVO(0, "", TipoCurrentItem);

}

the "EUGruppoVO" Constructor is :

public EUGruppoVO(Int32 id, String descrizione, String tipo)

{

this._id = id; // in the database the fields is a identity primary key

this._descrizione = descrizione;

this._tipo = tipo;

}

the "EUGruppoVO" implements "INotifyPropertyChanged"

the "EUGruppoItemsSource" is an instance of : "public class EUGruppoVOList : ObservableCollection<EUGruppoVO>"

2. Then I move to another row ( the RowEditEnded Event fire with "e.EditOperationType == GridViewEditOperationType.Insert" )The code in RowEditEnded Event Handler of the Grid is :

public void EUGruppoGrid_RowEditEnded(object sender, Telerik.Windows.Controls.GridViewRowEditEndedEventArgs e){if (e.EditAction == GridViewEditAction.Cancel) return;if (e.EditOperationType == GridViewEditOperationType.Insert)_eUGruppoService.Insert((EUGruppoVO)e.NewData);else_eUGruppoService.Update((EUGruppoVO)e.NewData);}

3. Then I move in the row previously entered, strangely the value of the "id" property of the current item has remained zero.I edit the row, when I move to another row the RowEditEnded Event fire again with "e.EditOperationType == GridViewEditOperationType.Update"but the "id" property of (EUGruppoVO)e.NewData is still zero, why ?

An extract of the XAML code is :...<telerikGridView:RadGridView x:Name="EUGruppoGrid" AutoGenerateColumns="False" CanUserFreezeColumns="False" ShowGroupPanel="True" ItemsSource="{Binding EUGruppoItemsSource, Mode=TwoWay}" CurrentItem="{Binding EUGruppoCurrentItem, Mode=TwoWay}" Margin="0,0,0,0"><telerikGridView:RadGridView.Columns><telerikGridView:GridViewComboBoxColumn DataMemberBinding="{Binding Tipo, Mode=TwoWay}" ItemsSource="{Binding TipoEUList, Mode=OneWay}" DisplayMemberPath="Descrizione" SelectedValueMemberPath="Codice" Header="Tipo" IsReadOnly="False" /><telerikGridView:GridViewDataColumn DataMemberBinding="{Binding Descrizione, Mode=TwoWay}" Header="Descrizione" IsReadOnly="False" /><telerikGridView:GridViewDataColumn IsVisible="False" DataMemberBinding="{Binding Id, Mode=OneWay}" Header="Id" IsReadOnly="True" /></telerikGridView:RadGridView.Columns></telerikGridView:RadGridView>...

An extract of the code behind is :...this.EUGruppoGrid.AddingNewDataItem += new EventHandler<Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs>(_tabelleViewModel.Controller.EUGruppoGrid_AddingNewDataItem);this.EUGruppoGrid.RowEditEnded += new EventHandler<Telerik.Windows.Controls.GridViewRowEditEndedEventArgs>(_tabelleViewModel.Controller.EUGruppoGrid_RowEditEnded);...DataContext = _tabelleViewModel

Thanks, Dario.

Binding To Collection from example not working

Hello! I was trying to get advantage from the RadTabControl component in my project and have it bounded to a collection I am going to use. I follow all the steps in the documentation, but in the end the tab names are still the name of the class and not some property string I want to use. I even made a project using your own classes (Person & ViewModel) thinking that something is wrong with my code and I still see "DataInfo.Person" at the name of each tab (DataInfo is my namespace)

I am using exactly your code:

                    namespace DataInfo {         
                public class Person {         
                    public Person( string name, int age ) {         
                        this.Name = name;         
                        this.Age = age;         
                    }         
                    public string Name {         
                        get;         
                        set;         
                    }         
                    public int Age {         
                        get;         
                        set;         
                    }         
                }         
            }         

                    namespace DataInfo {         
                public class ViewModel {         
                    public ViewModel() {         
                        this.Persons = new ObservableCollection<Person>();         
                        this.Persons.Add( new Person( "Ivan", 23 ) );         
                        this.Persons.Add( new Person( "Stefan", 34 ) );         
                        this.Persons.Add( new Person( "Maria", 16 ) );         
                        this.Persons.Add( new Person( "Michael", 78 ) );         
                    }         
                    public ObservableCollection<Person> Persons {         
                        get;         
                        set;         
                    }         
                }         
            }         

                    <UserControl x:Class="DataInfo.TabControl"

                            <TextBlock Text="{Binding Age}" />         
                        </Grid>

                      Background="White">         
                    <Controls:RadTabControl x:Name="radTabControl"         
                                            Margin="8"         
                                            ItemsSource="{Binding Source={StaticResource DataSource}, Path=Persons}"         
                                            DisplayMemberPath="Name"         
                                            ContentTemplate="{StaticResource ContentTemplate}" />         
                     
                </Grid>         
            </UserControl>         

Is there something I've misunderstood?

Thank you!
