Drag And Drop into a list nested in a listview

I've a window with a listbox on the left half and a listview on the right half. The DataTemplate of the listview is set to a template which contains a listbox, so for every row of the listview a new listbox is created. Now I want to drag an item from the left half of the window into one of the nested listboxes on the right half. The problem is, that the nested listboxes aren't registered as drop target zones, although the AllowDrop-prop is set to true. If I set the AllowDrop-Property of the listview to true, the DropQuery-Event is raised, but the e.Options.Destination is always the listview, not the listbox inside it.

Any help is appreciated.

Thanks

Setting Row height prevents Child Table from being shown

Hi,

In my application, I am showing a GridView with a Child Table.
As there a quite a lot of items in the GridView, I want the row height as low as possible.
When i set the row height in my grid, either by setting the RowStyle or by using a RowStyleSelector, my child table isn't shown anymore when i try to expand it.

Is there any other way of decreasing the rowheight of my GridView but still allow the Child Table to be shown?

Thanks,

Hans

The RadPane Style is not applied if it is in the RadTabControl and next RadTabItem

Hello.

I have simple application. In this application is one RadTabControl with twor RadTabItems and in both are RadDockings with one RadPane in each. Here is the code:

    
            <Grid> 
        
                    <telNavigationControls:RadTabControl x:Name="mainTabControl" Grid.Row="0" HorizontalAlignment="Stretch" 
        
                            VerticalAlignment="Stretch" DisplayMemberPath="Content" DropDownDisplayMode="Collapsed" ScrollMode="Viewport"  
        
                            Background="#dde1ea" telControlsControls:StyleManager.Theme="Windows7" SnapsToDevicePixels="True" SelectedIndex="0"> 
        
                        <!--FIRST TAB ITEM--> 
        
                        <telNavigationControls:RadTabItem Header="Tab 1"> 
        
                            <telNavigationControls:RadTabItem.Content> 
        
                                <telDockingControls:RadDocking HasDocumentHost="False"> 
        
                                    <telDockingControls:RadSplitContainer > 
        
                                        <telDockingControls:RadPaneGroup > 
        
                                            <telDockingControls:RadPane Title="Tab1" Style="{StaticResource TelerikRadPaneStyle}"/> 
        
                                        </telDockingControls:RadPaneGroup> 
        
                                    </telDockingControls:RadSplitContainer> 
        
                                </telDockingControls:RadDocking> 
        
                            </telNavigationControls:RadTabItem.Content> 
        
                        </telNavigationControls:RadTabItem> 
        
                        <!--SECOND TAB ITEM--> 
        
                        <telNavigationControls:RadTabItem Header="Tab 2"> 
        
                            <telNavigationControls:RadTabItem.Content > 
        
                                <telDockingControls:RadDocking HasDocumentHost="False"> 
        
                                    <telDockingControls:RadSplitContainer > 
        
                                        <telDockingControls:RadPaneGroup > 
        
                                            <telDockingControls:RadPane Title="Tab2" Style="{StaticResource TelerikRadPaneStyle}"/> 
        
                                        </telDockingControls:RadPaneGroup> 
        
                                    </telDockingControls:RadSplitContainer> 
        
                                </telDockingControls:RadDocking> 
        
                            </telNavigationControls:RadTabItem.Content> 
        
                        </telNavigationControls:RadTabItem> 
        
                    </telNavigationControls:RadTabControl> 
        
                </Grid>

On each RadPane is applied simple Style, which changes also the TitleTemplate. Here is it:

    
             <Style x:Key="TelerikRadPaneStyle" TargetType="{x:Type telDockingControls:RadPane}"> 
        
                        <Setter Property="CanUserPin" Value="False" /> 
        
                        <Setter Property="CanFloat" Value="True" /> 
        
                        <Setter Property="CanUserClose" Value="False" /> 
        
                        <Setter Property="ContextMenuTemplate"> 
        
                            <Setter.Value> 
        
                                <DataTemplate> 
        
                                    <telNavigationControls:RadContextMenu Visibility="Collapsed" /> 
        
                                </DataTemplate> 
        
                            </Setter.Value> 
        
                        </Setter> 
        
                        <Setter Property="TitleTemplate"> 
        
                            <Setter.Value> 
        
                                <DataTemplate > 
        
                                    <Grid > 
        
                                        <Grid.ColumnDefinitions> 
        
                                            <ColumnDefinition Width="Auto" /> 
        
                                        </Grid.ColumnDefinitions> 
        
                                        <Button Grid.Column="0" Width="100" Content="Test Button" HorizontalAlignment="Center"/> 
        
                                    </Grid> 
        
                                </DataTemplate> 
        
                            </Setter.Value> 
        
                        </Setter> 
        
                    </Style>

And here is the problem. When I start my application, the first RadPane in first RadTabItem is with applied style, but when I select second RadTabItem, the RadPane in this item is withou applied style.

Can you please tell me where is the problem or what I'm doing wrong ?

Thank You.

Stefan.

Vertical Stretch

I want to have 2 panes, one larger than the other with a split vertically. I was these panes to be stretched to the size of their container, in this case a grid row. So I have this

<telerikDocking:RadDocking x:Name="radDocking" Grid.Row="2">

<telerikDocking:RadSplitContainer InitialPosition="DockedTop" Orientation="Horizontal" VerticalAlignment="Stretch">

<telerikDocking:RadPaneGroup telerikDocking:ProportionalStackPanel.RelativeSize="200, 200">

<telerikDocking:RadPane Header="pane" />

</telerikDocking:RadPaneGroup>

<telerikDocking:RadPaneGroup telerikDocking:ProportionalStackPanel.RelativeSize="400, 200">

<telerikDocking:RadPane Header="pane" />

</telerikDocking:RadPaneGroup>

</telerikDocking:RadSplitContainer>

</telerikDocking:RadDocking>

However, this doesn't stretch to the grid row height. How can I get this to happen?

Thanks

                get         
                {         
                     return panel.CurrentLocation;         
                }         
                private set

3D Bar chart with multiple series

I am looking for a 3D Bar Chart control, where multiple data series can be plotted at a different Z axis value. There is a sample example available on CodeProject: http://www.codeproje...t_control.aspx.

The solution addresses what I need, but I was wondering if Telerik has an equivalent solution (With better look and feel).

I didn't see anything similar to this in the sample browser. I wanted to know if I can achieve something similar from current offering. If not do you plan to add something similar in near future?

change color of bars on bar graph

Hello,

I just recently started using Telerik controls for WPF and to be honest have found the documentation to be quite disorganized. It seems that everything wants to take you back to the demo project, which offers nothing but a sample of what the control CAN do, not how to do it, weird.....anyways, I am trying to do something very simple, which is to change the colors of the bars on a bar graph, or more generally, the colors of the lines on any type of graph. I have the graph working, it is data bound, and it looks great, but the default color of the bars make the graph blend in too much to the rest of the interface. Any suggestions? It seems like is should be a simple property of the graph, but I cannot find it.

Custom Insert Text?

This seems like a pretty simple request so I am hoping there is an easy way to satisfy it. Can we easily change the text of the insert new row label? I believe it starts out as insert new record or something along those lines and we would like to change the text to something else. Is this easily possible?

Adding Rows

I would like to have an empty, editable row in a telerik grid always available. When the user first selects this empty row or a cell in it, I would like the grid to then add a new row. Could you provide sample code for this? Thank you.
