Hi

I created a new wpf app and followed the information in the forum to make the main window a RadWindow.  When I execute the program I get a wpf navigation window with my RadWindow inside of it.   The RadWindow appears to be frozen,  Outside the Navigation window is another RadWindow that is not frozen.  Based on the forum guide I think I am doing everything correctly.  I am also using the latest version of the telerik libraries.  I am expecting to see only a main RadWindow with no navigation window.

1. - Created a new Wpf Application

2. Modified MainWindow.Xaml 

<telerik:RadWindow x:Class="CloudburstDataReader.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Header="Cloudburst Data Reader" Height="350" Width="525">
    <Grid>

    </Grid>
</telerik:RadWindow>

3. Modified App.xaml.cs

public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            new MainWindow().Show();
            base.OnStartup(e);
        }
    }

4. Modified CloudburstDataReader.cs

namespace CloudburstDataReader
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : RadWindow
    {
        public MainWindow()
        { 
            InitializeComponent();
        }
    }
}


    

When I bind a GridViewDataColumn to a DateTime field, I am not allowed to set the Time.  Seems like a reasonable expectation. 

The default state of the column seems to give us the worst of both worlds because the time is displayed when not edited but when we are in edit mode I can't change it.  If the default is just a calendar then don't display the time in the column.  If the default is to handle time then expose the RadDateTimeEditor instead of the RadDateEditor while editing.

How can I accomplish what I want?  Is it a setting in XAML or do I need to capture the column on creation and define it differently?  I'm always appreciative of XAML and Code examples.

Hi,

I am creating a wpf application with MVVM pattern. The application has a radscheduleview component with context menu attached to it. When user select the "Delete Note" menu item, how can I get all selected appointments into the list which I can then go through, and do desired manipulations to each appointment?

Currently I have a command which delete one appointment at a time. A new requirement is deletion of all selected appointments. Any ideas?

        public RelayCommand<CustomAppointment> DeleteNoteCommand
        {
            get
            {
                return deleteNoteCommand
                    ?? (deleteNoteCommand = new RelayCommand<CustomAppointment>(
                                          p =>
                                          {
                                              if (p != null)
                                              {
                                                  var message = new DialogMessage("Delete Note?", DeleteNoteCallback)
                                                  {
                                                      Button = MessageBoxButton.OKCancel,
                                                      Caption = "Delete Note",
                                                      Icon = MessageBoxImage.Warning
                                                  };
                                                  deletedNote = p; // global variable to send selected item to messenger
                                                  Messenger.Default.Send(message);
                                              }
                                          },
                                          p => (p != null) && (p.Source == NOTE));
            }
        }

Hi, in the following code I get an exception when i try to drag the content (not the header) of a RadTileViewItem

</Window>

Am I doing something wrong here? I tried it in in Q1 2015 release and in a release from 2014

The last part of stacktrace is

How can add possibility for selecting range of chart using radcartesianchart?

I want to round the corners on a RadComboBox, but I don't want to go through and edit the template for it. Is there way to do that without going through the hassle of doing that? Potentially just using a setter property or something to do it on the xaml side?

thanks.

Hello,

I have a RadGridView, it has 7 columns with boolean data. I want to disable each cell with a true value.

I created a style and a converter, I add the style at runtime using the grid DataLoaded event:



In the converter I get a GridViewCell object in the value parameter, but the GridViewCell.Value property is always null.

How can I pass the value of the cell to the converter?

Thanks in advance,

Alberto

I have a spreadsheet control I am going to use for data input.  Some cells will need data validation which will pop up a message about the error, and put the red circle around it.  I have the spreadsheet control on the form and set my Imports statements, I do not have a ribbon bar on the form.  We do not want to allow the users to change the form, just input data.  When I put in the following line:

Dim context as new NumberDataValidationRuleContext...

I get type not defined.  I will need to apply different rule types to different cells, some whole numbers, some decimals, some letters all with ranges. For example 8-12 for hole numbers, .5-3.0 for decimal, A-B for letters. 

I looked through the documentation and must have missed something.  How do I apply Validation to cells to ensure they are within the ranges?

Hello,

I am trying to add some control to the pane header, I saw this documentation about that, it seems that it's not very complicated using the TitleTemplate property.
The difference in my project is that I am creating the RadPane at runtime. Is it possible to programatically add a control to the pane header? Also I would like to add events to that control.

Thanks in advance,

Alberto 



 

I just updated to version 2015.1.225.45 and now I get these error messages:

The type reference cannot find a public type named 'PickerTextBox'. Line 2096 Position 74. D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml 

 The name "RadRangeControl" does not exist in the namespace "clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls". D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml


I don't use either of these controls in my application. The errors are showing up in the dll's XML;  Telerik.Windows.Controls.xaml


Any clues on how to resolve this are greatly appreciated!
