Hi,

Although I am not a Telerik user, I like to watch the news, and I encountered a problem while using the control RadDataForm in conjunction with the application theme Expression_DarkTheme.

In this situation the DataFormComboBoxField´s property DisplayMemberPath doesn´t work. Following your project 318767_RadGridView-WPF-AR-140 in this forum, I add a line in the MainWindow.xaml.cs constructor:

public MainWindow()

        {

            StyleManager.ApplicationTheme = new Expression_DarkTheme();

             

            InitializeComponent();

        }

After that the values are no longer displayed, only the object's name. When I select one, the value is displayed correctly.

Best Regards,

Sergio

Hi,
I was wondering if there's a way (with RadScheduler or RadSchedulerView for WPF) of resizing a day column in WeekView by clicking on its header and dragging it.

Thanks in advance.

Good morning

I'm using RadFilter to compose custom filters so my GridView has its IsFilteringAllowed property set to false.
is this the right way to hide the funnel icon in WPF?
In SL it works fine this way but in WPF the icon remains there...

Thanks in advance.

Hi,

I am using 2 nested collections in a graph, the first of which contains 3 series of identical length (x ranges from 0-220) and the second collection has 1 series that ranges from 0-450 in x values. In other words, my two collections do not have the same amount of points in them.

When I display the graph, all is fine except when I start using the ZoomScrolling feature. I use the default sampling of 200 points but when I zoom between x=100-240 the 200 sample points are all on the left side for the first 3 collections and all on the right side for the last collection. There are no points in the middle! The first three collections should be spread out between 100 and 220 and the last collection should have its samples spread out evenly across the zoomed part of the screen (see attached snapshot of full graph and zoomed part of graph).

Is this a known issue? Is there a workaround? I am using 2011.2.920.35 in Visual Studio 2010 in a WPF project.

Thanks

Has there been any consideration for creating a WPF &\or Silverlight version of the infamous PropertyGrid?  I think this would be a very useful control to have in your arsenal.

When I change a radribbonview control's theme ,RadRibbonGallery lost its scroll bar and button. Any suggestions?
first capture image is before use theme, second is after use theme.

code:       
         Theme ConvertToTheme(string themeName)
        {
            if (string.IsNullOrWhiteSpace(themeName))
                return new Windows7Theme();
            return (Theme)typeof(Theme).Assembly.CreateInstance(string.Format("Telerik.Windows.Controls.{0}Theme", themeName));
        }
    

        void SetGlobalTheme(Theme theme)
        {
            StyleManager.ApplicationTheme = theme;
            StyleManager.SetTheme(radRibbonView1, theme);

        }

        private void RadRibbonRadioButton_Click(object sender, RoutedEventArgs e)
        {
            RadRibbonRadioButton radioButton = (RadRibbonRadioButton)sender;
            Theme currentTheme = ConvertToTheme(radioButton.Text);//Button's content is theme name, like Office_Silver
            SetThemeToAllViews(currentTheme);
        }

Hello Telerik Team! I'm working on WPF Project using Telerik Controls. My goal is to build an application for a Medic Clinic, and this app must run on a pendrive, so we are using MS Access as Database. I'm having problems to bind ScheduleView to Access Database.



Before I sent  this post, have you sure I had tried different ways to solve this problem. So, direct to the point, when I try to Insert or Update an Appointment (CustomAppointment), I always receive an syntax error in INSERT INTO or UPDATE statement. The error is raised because DateTime format of Start/End properties from ScheduleView. I'm using a OleDBCommand with Parameters, as you see below.



I already tried pass date/time values surrounded with single quotes, double quotes, sharp (#), and DateTime as you can se in this code. Also I tried OleDbType.DBDate. OleDbType.Date and OleDbType.DBTimeStamp. But always got the same Syntax Error in INSERT INTO.



Could you please help me?

I'm using VS2010 + SP1, WPF Application, Target .NET Framework 3.5, Access 2007 Database (mdb) and Telerik WPF Controls Q1 2012.

I am quite new to all of this, so it maybe no surprise that I would be a little lost...
Here is where I am at: I would like to get the CustomerID (from a viewModel) when a row is selected, to pass it to anotherViewModel to filter orders matching the currently selected Customer.
in XAML I have:
In the viewModel, I have a delegate command.
I have been following the example in the documentation about RadEventsToCommandExamples, and when I look in the debugger, I can see that my Object is of type Telerik.Windows.Controls.SelectionChangeEventsArgs, but if I try to cast the Object to this, I get an error, as it find Windows.Controls.SelectionChangedEventsArgs (note the difference between change and changed).
I did try to cast it from RadRoutedEventArgs, but I am not too sure how to do.

How should I do? Looks like a bug to me, but I would really like to know about a work around. Thanks in advance!

for the last 2 hours I've been trying to figure this one out. i have a column displaying an enum value. the enum value is displayed using a custom template and works fine. every enum value has its corresponding icon. now i was asked to provide a way to edit all the selected rows at once. the data behind are observableobjects (INotifyPropertyChanged). My code is simple, after setting a value in a dialog and accepting, I modify all the selected elements property to the new value. this works fine for string and double by the way. it also mostly works for my enum, but sometimes (mainly when i repeat this process quickly) i get a crash with the (consistent) error listed below.

I removed my template and the code worked. if i only display text in my template and no icon, it also seems fine. the main reason, why i think this must be telerik related, or at least a combination effect: I dont get an exception in my own code and can not debug a thing. if i edit the cells directly i also have no problems. it only seems to occur by modifying multiple data-objects at once.

I've also tried the following: prevent my objects notifying that the enum value has changed -> no exception. then calling rebind on the grid -> same exception.
