The most bizarre situation.  I am trying to do a drag/drop within the treeview.  But for some reason, my DragEnded event will never fire.  I have put it on both the Treeview and it code.  But when I run the code, I just get the error "There is not source code available for the current location".  Other events will work fine like PreviewDragEnded.  I have tried two different datasources.  Both an ObservableCollection and then also a link query cast ToList().  I have also tried to re-create these events and it makes no difference.  By the error, it acts as if I don't have a handler, but I do!  You will notice I have tried the handler in both code and markup.

Version: 2009.3.1314.35

This is based off a sample you put up describing how to change the index of the sort

Here is what I have in XAML and in code:

<

 

<Telerik:RadTreeView x:Name="treeColumns" MinHeight="500" DragEnded="treeColumns_DragEnded"
                        VerticalAlignment="Top" SelectionMode="Multiple" IsEditable="True" IsDragDropEnabled="True"
                        ItemTemplate="{StaticResource ItemTemplate}"
                        ItemsSource="{Binding Converter={StaticResource convWorkflow}}"></Telerik:RadTreeView> 

 

 

 

 

 

 

treeColumns.DragEnded +=

new RadTreeViewDragEndedEventHandler(treeColumns_DragEnded);

 

 

 

 

 

 

private void treeColumns_DragEnded(object sender, RadTreeViewDragEndedEventArgs e)
        {
            int index;
            WorkFlow draggedItem = e.DraggedItems[0] as WorkFlow;
            WorkFlow targetItem=e.TargetDropItem.DataContext as WorkFlow;
            if (draggedItem != targetItem)
            {
                switch (e.DropPosition)
                {
                    case DropPosition.After:
                        index = e.TargetDropItem.Index + 1;
                        break;
                    case DropPosition.Before:
                        index = e.TargetDropItem.Index - 1;
                        break;
                    case DropPosition.Inside:
                        index = e.TargetDropItem.Items.IndexOf(draggedItem);
                        break;
                    default:
                        index = -1;
                        break;
                }
            }
            else
            {
                index = e.TargetDropItem.Index;
            }
            draggedItem.SortOrder = index;
            DataAccess.ctx.SubmitChanges();
        }

Hi,Telerik.

Hi, 
we updated to Telerik 2010 Q1 Beta, and now we can drag the floating window outside of the main window, but we no longer can drag and drop from one floating window into another or into the main window.
What should we do to make the drag and drop work between the windows?
Thanks
Nick

Greetings All!

Hi,

With the gridview I need to override the delete functionality...When a user hits the delete key on a row in the grid I want to set my entity to Inactive, rather than remove it from the collection.

I tried hooking up KeyDown but it never fires for the delete key, the default functionality of removing the row happens.
I tired hooking up KeyDown with CanUserDeleteRows set to false and the key down never fires for the delete key.
I can use other keys such as backspace etc. but our users want to use delete.

The only thing that seemed to work was to handle the Deleting event and do what I want and set e.Cancel to true. The problem with this event is I can't selectivly remove from the collection ie. if my record is new/unsaved and they hit delete i want it removed but if it's a saved record that they delete i want it marked on screen as inactive. The cancel seems to be an all or nothing. 

What's the best way to do the functionality that i need?

I downloaded RAD Controls for WPF set and didn't manage to find in Demos an example of master-detail representation of a GridView. For example, for OrderHeader - OrderLines view implementation. How is it possible to set detail part of a view as CardView with the possibility of editing database records?

Hi,

I use the RadGridView and I want to have 2 GridViewComboBoxColumn in there. But there are a lot of problem:
1. The Comboboxes should always be visible, but they are only visible if the user double-clicks in the cell. Therefore, I tried to put a normal Combobox in the DataTemplate of the Cell-Template but then
2. Databinding is not working any more. And
3. Databinding with Enums is not working at all. If I bind my enum to the normal GridViewComboBoxColumn the data is showing up wenn the user double clicks, but then it is not possible to select any other cell in the grid and everything stood still.
4. How can I preselect the current dataitem value in the combobox? The initial value of all comboboxes is always empty ....
Please help!

That's my code:
XAML:
<telerik:RadGridView x:Name="grid" Grid.Column="2" Grid.RowSpan="15" AutoGenerateColumns="False" ItemsSource="{Binding}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Plate Id" DataMemberBinding="{Binding Name}">            
                <telerik:GridViewComboBoxColumn Header="Dilution Factor" DataMemberBinding="{Binding DilutionFactorId, Mode = TwoWay}" ItemsSource="{Binding}" DisplayMemberPath="Name" SelectedValueMemberPath="Id" UniqueName="colDilFactor">
                    <!--<telerik:GridViewComboBoxColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel>
                                <ComboBox x:Name="internalCboFactor" ItemsSource="{Binding}" SelectedValue="{Binding DilutionFactorId}"></ComboBox>                               
                            </StackPanel>
                        </DataTemplate>
                    </telerik:GridViewComboBoxColumn.CellTemplate>-->
                </telerik:GridViewComboBoxColumn>
                <telerik:GridViewComboBoxColumn Header="State" DataMemberBinding="{Binding State}" ItemsSource="{Binding}" UniqueName="colState">
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

C#
((GridViewComboBoxColumn)grid.Columns["colState"]).ItemsSource = Enum.GetNames(typeof(PlateStateEnum));
 ((GridViewComboBoxColumn)grid.Columns["colDilFactor"]).ItemsSource =                     _handler.GetProvider().LoadDilutionFactors(typeId);

                //ComboBox cboFactor = grid.Columns["colDilFactor"].FindName("internalCboFactor") as ComboBox;
                //if(cboFactor != null)
                //    cboFactor.ItemsSource = _handler.GetProvider().LoadDilutionFactors(typeId);

            }

Thx in advance!
