I have a hierachical grid view that binds to a datasource with autogenerate columns set to true.

I have a timer on my screen that the user can switch on and off to 'auto refresh' the grid

I have noticed that when i next cycle trhough and fetch data and bind, the data in the child tables doesnt get cleared

for example i have 4 rows in my table, each with 2 rows underneath .. next time i refresh i still have 4 rows but they each have 4 underneath

I can clear this by clearing them all before i rebind .. by i thought that binding would sort this out without having to clear them

is the working as it should?

Can't use DragEnded

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();
        }

What should we do to make the drag and drop work between the windows?
Thanks

Looking for a way to restrict a RadPanel to only be "dockable" in it's original parent RadPanelGroup? Basically, preventing my tool panels from being able to dock with my DocumentPanel.

Any ideas?

Thanks!

RowDetails and Text Wrapping

Hi,

We've replaced our earlier use of child grids with a simplified RowDetails, something that looks like this:

                           <telerik:RadGridView.RowDetailsTemplate>         
                        <DataTemplate>         
                            <Grid>         
                                <Grid.ColumnDefinitions>         
                                    <ColumnDefinition Width="80" /> <!-- A kind of margin we're using -->         
                                    <ColumnDefinition Width="*" />         
                                </Grid.ColumnDefinitions>         
                                <!-- Here there is a component that appears in column 0 -->         
                                         
                                <!-- The actual description  -->         
                                <TextBlock          
                                    Grid.Column="1"         
                                    Text="{Binding Description, Mode=OneWay}"          
                                    TextWrapping="Wrap"/>         
                            </Grid>         
                        </DataTemplate>         
                    </telerik:RadGridView.RowDetailsTemplate>         

When viewing this, the TextBlock fails to wrap the text.

Based on our understanding, this is because the owning Grid is taking more than the visible width. However, it's possible there's a mistake here.

Can you help us understand why the TextBlock is not wrapping?

Thanks,

yonadav

Overriding delete functionality

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?
