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

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"

                                            Margin="8"         
                                            ItemsSource="{Binding Source={StaticResource DataSource}, Path=Persons}"         
                                            DisplayMemberPath="Name"         
                                            ContentTemplate="{StaticResource ContentTemplate}" />         
                     
                </Grid>         
            </UserControl>         

Is there something I've misunderstood?

Thank you!

RadTileView question

Hello,

I have been working with the radTileView. It's going to do what I need it to do in most cases. However, when there are only a few items the RadTileViewItems take the full space proportionally. It doesn't matter if I set the TileState="Minimized" or TileState="Restored" and the RadFluidContentControl ContentChangeMode="Manual" and State="Small". The controls do appear in the proper state, however the border of the control takes the remaining space causing the controls to be spaced evenly in the area. Even if I manually set the maxHeight and maxWidth of the radTileViewItem.

Is there a way to cause the tiles to be top left justified and leave blank space to the bottom and right when minimized or restored?

The other thing is that when I have a radTileView item maximized and the minimizedItemsPosition="Right" the same kind of spacing issue occurs. I would like them to appear like they do in the "Tile States" BMW section of this link - http://www.telerik.com/products/silverlight/tileview.aspx

I have also tried this with the sample code by adjusting the number of BMW tileViewItems and the size of their container.

I would like to use it more like a list box with very small items taking advantage of the eye candy moving them around and the maximize to edit the information in the control.

Thank you for your help.

where has columnwidthsmode gone??

Hi,
I've just updated my WPF binaries to 2010.1.309.35 from 2009.3.1208.35 and it seems that the ColumnWidthsMode enum is missing could someone please explain to me what has happened to it?

Also, I've seen examples using the telerik:HierarchicalDataTemplate with the treeview control with regards to binding to the individual items CheckState property but can't seem to find that class either. Please help asap as this is rather urgent.

Thanks,
Peter.
