Drag and Drop between TreeView without Visual Queue on one side

I have a two TreeView controls, one on the left side and one on the right side. The users should be able to drag items from the left side to the right side, but not the other way around. I have this functionality working, but I want to remove the visual elements (Drag Preview, Preview Line and Tooltip) when the drag is over the left side so that the users don't think that they are allowed to drag.

I've tried setting the following:

IsDragPreviewEnabled="False"
IsDragTooltipEnabled="False"
IsDropPreviewLineEnabled="False"

But I still get all the visuals. I'd be fine with the visual queue that shows the red indicator saying no to the user.

Telerik RadGrid Control

Hi,
I have a question regarding the telerik RadGrid control. For the grid in my application I use InPlace editmode and the grid is empty on page load, so the user has to fill in some data. My problem is that when moving with tab key or with mouse in the grid there is no way to recognize the current cell, where the user is typing some data. I want to catch the event when the user fill out the current row of the grid and after that switch to the other row. How to make this possible?

I would appreciate your help. Thank you in advance.

ColorMeasureScale examples and docs???

Are there any varied examples of usage and/or documentation that explains how to use this? The docs online right now are very sparse. I know it is new, but I really need to figure out how to handle this properly. I'm getting all sorts of wacky results when I am trying things my users are asking for. ;)

For example, just doing a two color map from data that runs from 0-100 where red is triggered when at a value of 79 or less, anything 80 or above is green. That was a beast to figure out and even when I got it working I see that the color values are changed...it's trying to blend them just a bit. Now I'm being asked to show multiple shades of red depending on value, but all >80 are one green. Is that even possible, if so, how? I'm not quite und4erstanding the Step mode with Min and Max and TickMarkStep....Count mode does not seem to work for this at all.

Drag & Drop in WrapPanel?

Hello,

I am wondering if it is possible to use your control to gain drag & drop behaviour inside a wrapPanel with content generated from XML. It can be list of boxes(borders or grids). I found only samples of drag & drop inside treeview and listbox on you website. Do you have any sample that works in wrapPanel? Thank you in advance!

Problem binding ComboBoxColumn

I'm having some trouble with the ComboBoxColumn. Here is my code:

<telerik:GridViewComboBoxColumn

DataMemberBinding="{Binding ActionID}"

Header="Action" UniqueName="ActionID"

SelectedValueMemberPath="ActionID"

DisplayMemberPath="Name"

ItemsSourceBinding=

"{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=telerik:RadPane},Path=viewModel.References.ActionList}"

/>

The rest of the columns are binding as expected. I was originally using ItemsSource and saw a thread that said to use ItemsSourceBinding instead. But neither one is working.

FYI: I'm also having trouble databinding several other gridviews using the same RelativeSource binding (but to different properties). I know my properties have items in them. I can see it when I debug, but the binding just isn't working for some of my controls. Other controls that are also bound using RelativeSource are working.

Is there something wrong with my comboBoxColumn or is there a limit on how many RelativeSource bindings I can use?

SelectionBoxTemplate not updated

Hello,
I´m want to be able to multiselect in a ComboBox and therefore uses a SelectionBoxTemplate. But there is a strange problem.

    
            <totally:RadComboBox  Grid.Column="1" Grid.Row="0" Grid.ColumnSpan="3" Name="StatusarComboBox" HorizontalAlignment="Stretch" 
        
                                  ItemsSource="{Binding ARStatusar}" IsTextSearchEnabled="False" MaxWidth="190" > 
        
                                <totally:RadComboBox.ItemTemplate> 
        
                                    <DataTemplate> 
        
                                        <CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}" Content="{Binding Text}" /> 
        
                                    </DataTemplate> 
        
                                </totally:RadComboBox.ItemTemplate> 
        
                                <totally:RadComboBox.SelectionBoxTemplate> 
        
                                    <DataTemplate> 
        
                                        <TextBlock Text="{Binding Owner.CheckedItems, Converter= StaticResource ValueConverter}, UpdateSourceTrigger=PropertyChanged}"/> 
        
                                    </DataTemplate> 
        
                                </totally:RadComboBox.SelectionBoxTemplate> 
        
                            </totally:RadComboBox>

The comma separated text returned from the ValueConverter that shows the selected items does not always update. Only mouse clicks sometime updates the text. And after it starts working, it seems to always work. It also seems to always work when leaving the ComboBox using enter.

I´ve used this example:
http://www.telerik.com/community/forums/silverlight/combobox/multiselect-option-in-combo-box.aspx

Any ideas to this strange behavour? I want to be able to only use mouse clicks.

Best regards,
Anna

Filtering on an enum collection

Suppose you have the following definitions:

public enum Category { Spicy, Fat, Tasty, Expensive};

public class Dish

{

public string Name {get; set;}

public Category[] Categories {get; set;}

}

I show a collection of Dish objects in a RadGridView. As property Categories is a collection I concatenate the values into a single string, e.g. "Spicy, Fat". Now I would like to add some custom filtering behavior that makes it possible to this on the Categories column:

Show a sorted list of all the values in the Category enum (or perhaps only the values that are used by the Dish objects in the grid)
Use a CheckedList so that more than one value can be selected.
When more than one Category is used in the filter I want to see all items having at least one of the grades (i.e. an OR condition).

Example:
Grid content [Name: Categories]
- Filet Mignon: Expensive, Fat
- Sausage: Fat
- Thai Curry: Spicy, Tasty

If I select values Fat and Expensive I should see the rows for FiletMignon (matches both) and Sausage (matches Fat).
If I select values Spicy and Expensive I should see the rows for FiletMignon (matches Expensive) and ThaiCurry (matches Spicy).

I would be more than grateful for some help on this so thanks in advance!
