Hello,

I can't ever seem to get the vertical scroll to appear. The regular MS Windows grid scrolls always appears. This control is being added to another grid inside a RadTabItem. I would like the scroll to kick in when ever the screen size requires it without having to set hard Heights and Widths. Thanks.

search filter

Hi,

I'm trying to implement filter search in the grid

This is the code:

private void OnFilterByTextCommand(string parameter)
  {
   var compositeDescriptor = new CompositeFilterDescriptor
                             {
                               LogicalOperator = FilterCompositionLogicalOperator.Or
                             };



   foreach (GridViewColumn column in RadGrid.Columns)
   {
    var dataColumn = column as GridViewDataColumn;
    if (column == null) continue;

    object obj = null;

    try
    {
     if (dataColumn != null)
       obj = Convert.ChangeType(parameter, dataColumn.DataType);
    }
    catch
    {
     continue;
    }
    if (obj == null) continue;

FilterOperator op = dataColumn.DataType.IsValueType ? FilterOperator.IsEqualTo : FilterOperator.Contains;

    FilterDescriptor filterDescriptor = new FilterDescriptor
                                        {
                                          IsCaseSensitive = false,
               Member = dataColumn.UniqueName,
               Operator=op,
               Value=obj
                                        };

    compositeDescriptor.FilterDescriptors.Add(filterDescriptor);


   }

   RadGrid.FilterDescriptors.Add(compositeDescriptor);

  }

I get exception in the columns that the column type is not the same as the

Item source collection in this binding member

If I bind the column to same data type and us one of this data properties

The exception is cant cast beaten the types

Someone know this problem?

Maybe I need to change the filter method?

Best Regards

Ehud

cannot undock window with 3 monitors

Hi,

Simply running your Q1 2010 demo for the wpf docking does not work correctly with my multiple monitor configuration. I currently am running Windows 7 and have 3 monitors set-up to extend my desktop. One of my monitors is plugged into a usb video port replicator docking port which is where the problem occurs. My configuration is my center screen is my primary, then I have a screen to the left and another one to the right. If I drag a window to the right it works as expected. I am unable to drag to the left, simply does not recognize the boundries or something. If I run the whole application on the left monitor and try to undock a window, the undocked window just vanishes, not even letting me drag it around. The docking port I use is the HP HSTNN-S01x. Currently I use the Actipro docking control and do not encounter this issue.

Thanks

Rick

Modal RadWindow in WebProject

Hello,
I have a problem with using ShowDialog method of RadWindow in WebBrowser. A new window appears, but ShowDialog should susspend by main application. I use Close callback to resolve this problem, but it's not a good solution for complicated application.
I really need to freeze code execution when modal dialog appears.

Which BING-license is needed for commercial use of RadMap(BING-provider)

Hi,

searching the internet I found following statement:

Q: Can I use Bing Maps (Virtual Earth) within a Windows Forms or WPF Desktop Application?

A: As far as Licensing, you’ll need to contact Microsoft. The “Microsoft Virtual Earth Platform API Terms of Use” doesn’t really cover this specific usage scenario.

Microsoft doesn’t have a Window Forms or WPF control that you can just drag onto a Window, but you could access the Web Service from your application or display the JavaScript Map Control within an embedded WebBrowser control.

(http://pietschsoft.com/post/2009/06/02/Bing-Maps-for-Enterprise-Virtual-Earth-Licensing-FAQ-Questions.aspx)

Do I really have to contact Microsoft for using RadMap or do you already know which licensing-model is needed for commercial use of your control?

Best Regards
Steffen

MVVM DelegateCommand binding error

Hi,

I saw a similar issue posted in the Silverlight forum. I am not able to use the solution presented there because I need to instantiate my view model with parameters from the view. I am trying to bind a Composite WPF DelegateCommand to a column cell template in my RadGridView.

When I run the application I get this error in the output window:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=LayoutRoot'. BindingExpression:Path=DataContext.StopCommand; DataItem=null; target element is 'Button' (Name='StopButton'); target property is 'Command' (type 'ICommand')

If I bind the command to a button outside the RadGridView it works as expected.

I have the following XAML:

    
            <Window x:Class="MVVMCommand.MainWindow" 
        
                    x:Name="LayoutRoot" 
        
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                    Title="MainWindow" Height="300" Width="300" 
        
                    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"> 
        
                <StackPanel> 
        
                    <Button Content="This one works" 
        
                            CommandParameter="42" 
        
                            Command="{Binding ElementName=LayoutRoot, Path=DataContext.StopCommand}" /> 
        
                        <telerik:RadGridView Name="radGridView1" ItemsSource="abcd"> 
        
                        <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewColumn Header="Start"> 
        
                                <telerik:GridViewColumn.CellTemplate> 
        
                                    <DataTemplate> 
        
                                        <Button Content="This one does not"

                                                CommandParameter="42" 
        
                                                Command="{Binding ElementName=LayoutRoot, Path=DataContext.StopCommand}" /> 
        
                                    </DataTemplate> 
        
                                </telerik:GridViewColumn.CellTemplate> 
        
                            </telerik:GridViewColumn> 
        
                        </telerik:RadGridView.Columns> 
        
                    </telerik:RadGridView> 
        
                </StackPanel> 
        
            </Window>

The view model looks like this:

    
            using System; 
        
            using System.Collections.Generic; 
        
            using System.Linq; 
        
            using System.Text; 
        
            using Microsoft.Practices.Composite.Presentation.Commands; 
        
            namespace MVVMCommand 
        
            { 
        
                public class MVVMCommandViewModel 
        
                { 
        
                    public DelegateCommand<object> StopCommand { get; set; } 
        
                    public MVVMCommandViewModel(string s) 
        
                    { 
        
                        StopCommand = new DelegateCommand<object>(StopCommand_Execute); 
        
                    } 
        
                    void StopCommand_Execute(object o) 
        
                    { 
        
                    } 
        
                } 
        
            }

My code-behind:

    
                public partial class MainWindow : Window 
        
                { 
        
                    MVVMCommandViewModel _viewModel; 
        
                    public MainWindow() 
        
                    { 
        
                        InitializeComponent(); 
        
                        _viewModel = new MVVMCommandViewModel("42"); 
        
                        this.DataContext = _viewModel; 
        
                    } 
        
                }
