Hello!

I am having some problems with the GridViewComboBoxColumn that is databound. In the grid I am displaying postal codes. And each postal code belongs to a country. The country column is a GridViewComboboxCOlumn (Item source is a list of countries from the DB - Linq2SQL). Now I have 2 problems.
The fist is that the column Country is empty until I start scrolling (am I missing something?).

The second is that the scrolling is very slow. If I don't use the combobox the grid is fast again.Is there any way to make it faster?

I would also like to filter this column, but it only offers me ContryID's.  But if you use Contry.Name as DataMemberBinding, the Grid
updates all the Countries with the same name..

Thanks!

p.s. Yes I have looked at the demos example and it didn't help :-/

Hi,
we want to buy the new version of telerik controls because we are interested in RichTextEditor and PdfViewer for WPF.
We have some question before decide:
Is it possible to :
- convert review of text selection in highlight text when the document is converted in pdf?
- decide witch part of document is editable? We need to define some read only region in document.
- insert existing document as attachment of principal document? We need to embed other pdf documents. We know that in pdf is possible and we have do with iTextSharp. If is not allowed, is it possible to insert custom xaml tag to intercept the pdf generation and manage with our procedure?

Thanks

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?
