I'm trying to remove the built-in binding of the ESC key to the DiagramCommands.CancelEdit command. I've tried both approaches outlined here:

http://www.telerik.com/forums/override-keyboard-copy-paste-controls

with no success. The first approach successfully registers a new command, but the existing default command is still executed. I need to remove that default behavior.

Both the InputBindings and CommandBindings collections are empty after the diagram has been loaded, so I'm assuming that these default command handlers are stored elsewhere?

Am I approaching this the right way, or is there an easier way to handle this requirement?

Hello,

I want to set a custom user control as an entry for some properties (full MVVM support). If the user clicks the button a custom file selector (modal) should be shown. If the user selects a file, the file path should be shown in the textfield and also should be bind to the changed property in the propertygrid.

UserControl: A grid with a textfield and a button

<UserControl x:Class="EN.Editor.UI.ImageSelector"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:local="clr-namespace:EN.Editor.UI"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d"
             Width="100"
             >
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"></ColumnDefinition>
            <ColumnDefinition Width="30"></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <TextBox Grid.Column="0" Name="txtPath" Text="{Binding ImagePath, Mode=TwoWay}" />
        <Button Grid.Column="1" Command="{Binding SelectFileCommand}" CommandParameter="{Binding}" Content="..." />
    </Grid>
</UserControl>

 

ViewModel of the User Control (set as DataContext in Code behind)

public class ImageSelectorViewModel : ViewModelBase
   {
       private string imagePath;
 
       public DelegateCommand SelectFileCommand { get; private set;}
 
       public ImageSelectorViewModel()
       {
           this.SelectFileCommand = new DelegateCommand(x => SelectFile());
       }
 
 
       public string ImagePath
       {
           get { return imagePath; }
           set
           {
               if (this.imagePath != value)
               {
                   imagePath = value;
                   OnPropertyChanged(() => ImagePath);
               }
           }
       }
 
 
       private void SelectFile()
       {
           FileSelector fs = new FileSelector("Choose file");
           if (fs.ShowDialog() == CommonFileDialogResult.Ok)
           {
               this.ImagePath = fs.FileName;
           }
       }
   }

 

I set the user control as a custom editor attribute on the autogenerated item of my property grid

[Display(AutoGenerateField = true, Name = "Video Transition")]
      [Telerik.Windows.Controls.Data.PropertyGrid.Editor(typeof(ImageSelector), EditorStyle.None)]
      public string NavigateToMovie
      {
          get
          {
              return this.navigateToMovie;
          }
          set
          {
              if (this.navigateToMovie != value)
              {
                  this.navigateToMovie = value;
                  this.OnPropertyChanged(() => NavigateToMovie);
              }
          }
      }

 

I've tried many different ways, but the click command isn't triggered. If I replace the click command on the button with a Click event handler the file selector is shown, but the selected file path isn't set on the property in the property grid. I've also tried to set the targetProperty Attribute to "ImagePath" but also without success.

For better code separation I need the full MVVM style.

I've spent lot of hours to get this done - without success.

What's wrong with my code? Thanks.

Currently I'm using the themes Visualstudio2013 for gantt view. 

I only want to change background in one case and others would like to normal in the themes .

I found the sample "Tasks with different color" in the SDK.  But the sample didn't work well. the fonts color , progress bar color are reset.

 Any suggestion for this situation?

 

Thanks

Hi,

I understand from this http://www.telerik.com/forums/parentrow-problem that it is an expected beahvior.

I can't disable virtualization as it leads to performance issues.

I might have huge tree items in my application and i'm trying the locate the parent row on left arrow key down (the parent item will not be in visible area).

I cannot get the parent object as this is common behavior implemented in common library.

Please let me know if there is any other workaround.

Hello All,

     I'm trying the tabcontrol for the first time, and  am very curious as to do I create a new view/viewmodel pair for each tab or handle everything in the first pair where the overall top tabcontrol is based???  I think that I would like to have separate ones for ease in development but I haven't figured out as to how to assign them to the tab items...  Or is it just better to have in all in one?

 

What am I missing?  

 

Any help would be greatly appreciated,

Thanks in advance,

Kevin Orcutt
