I am working on some legacy code, I have RadTreeView with Item template which expand the hierarchy at doubleclick, I want to add a contextmenu which expand the hierarchy in the same way, problem is that there is no command to bind to expand nodes. How can I have the context menu work in the same way as the itemtemplate?

Hello,

I have the following requirements:

• When the user enters from outside the grid into the empty grid a new row should be created and the second cell should be selected in edit mode.
• When the user enters from outside the grid into a grid with existing rows, the second cell should be selected in edit mode.

I am using the enter-key to move to the next field in a particular viewmodel, instead of the tab-key.

How can I accomplish this, I tried searching a solution but couldnt find anything that accomplish this when entering the grid from outside?

Any help would be greatly appreciated.

Hi, 

I'm trying to set the background color for a disabled MultiColumnComboBox using a style, without succes.  Here's my code

Any ideas ?

I have a radcombobox that has a list of checkboxes that has multiselect. 

Two questions. 

1. I find that I need to get the most current item selected. With that said, how do I get the most current row(either by Id or by Index)

2. Second, my radcombobox has two types of "events" i need to worry about. One is when the row is clicked and highlighted and another one when user clicks the checkbox itself. If I click the row , I manually search for the item on the Viewmodel and mark the item checked to check the checkbox of that row. My issue is, if the user clicks the checkbox, I can trigger the command of the viewmodel and I will pass the s

Hi,

I'm trying to change the borderbrush of the Dockresizer.

What I found out, is that the dockresizer is part of the RadSplitContainer.

I cannot create a template copy of that control because Blend throws an error (btw. I can create copies of other telerik controls like documentmanager).

Any ideas?

Hello,
I would like to ask about context menu of PDF viewer.

So, I have PDF viewer (which is located in some UserControl), it works fine. In my app I allow to user creating of custom bookmarks - just some name and page number. One of the ways, how can user create own bookmark - right click and choose create bookmark in context menu. To create this I would like to use custom RelayCommand, which is in ViewModel of MainWindow and also uses some properties from ViewModel of MainWindow.

So, there is some problem. Since PdfViewer has it own DataContext (Command Descriptors), I can't use PlacementTarget to get some information from Window/UserControl DataContext (I tried relative source - it doesn't work). I found a solution - I created addition class with own RelayCommand, that works with STATIC variables (instance of PDF viewer to get current page) and methods (to create bookmark) from ViewModel. But I really dont like it really this solution.

So, I would like to ask you, how can I use my custom command from ViewModel in context menu of Pdf viewer? Or at least how can I pass CurrentPageNumer as argument, when I click on my custom menu item (command from custom class, which is initialized as static resource) in contextmenu of PDFviewer?

Now it looks like that:
<telerik:RadMenuItem Header="Create Custom Bookmark" Command="{Binding SomeCommand, Source={StaticResource customClass}}"    
                                                 Visibility="Visible" >

Thank you in advance!
Best regards,

Hi guys,

I want to make ExpressionEditor supports custom operators, and use those operators to replace existing one. For example, I want to use "!=" instead of "<>" for "not equal", and use "&&", "||" accordingly. I read the documentation and know how to customize the nodes in the tree, but how about features related to parsing? How to let the parser know the custom operators we defined?

PS: I'm using the latest WPF controls.

Hi,

I enabled filtering on a radcombobox (see below for the xaml). 

When the combobox gets focus the dropdown opens. Next, when I type some characters in the combobox, the filter works correctly and narrows down the resultset to lets say 2 items. Next  I want to be able to click once on the second item in the filtered dropdownlist and pass it on (i.e. it will be used to highlight it in a radtreeview). What happens now is that the first click will just set selecteditem to the clicked item and show it in the combobox. I need to enter (so a second user input) to pass it on.

Is it possible to directly select and pass on an item from a filtered set of items with just one click? One option I considered is using a previewMouseDown event, which is hit after just one click, but than the top item in the filtered list is passed on as selecteditem, even though I clicked on the second item. 

<telerik:RadComboBox  IsEditable="True"  IsFilteringEnabled="True" IsTextSearchEnabled="True" TextSearchMode="Contains" StaysOpenOnEdit="True" OpenDropDownOnFocus="True" ItemsSource="{Binding Locations}" DisplayMemberPath="Description"    KeyDown="CboSearchLoc_KeyDown>

Thanks,

Hi,

Is there a way to implement the bar series as in the image attached? The gradient is not necessary.

Currently I'm styling the same bar series as cluster and the goal is to format the top one so that instead of the bar it display the category

But I'm failing. 

Thanks and regards
