FindCarouselPanel in RadCarousel

Hello ,

I have a problem about the method FindCarouselPanel().
Here is the code i wrote:

    
            <Style x:Key="RadCarouselStyle1" TargetType="{x:Type telerik:RadCarousel}">  
        
                        <Style.BasedOn> 
        
                            <Style TargetType="{x:Type telerik:RadCarousel}">  
        
                                <Setter Property="Template">

                                                <Grid.ColumnDefinitions> 
        
                                                    <ColumnDefinition Width="50*" /> 
        
                                                    <ColumnDefinition Width="50*" /> 
        
                                                </Grid.ColumnDefinitions>

                                                </Border> 
        
                                            </Grid>

                        </Style.BasedOn> 
        
                    </Style>

this is the template i'm using,

<telerik:RadCarousel x:Name="radCarousel" Style="{DynamicResource RadCarouselStyle1}"/>

In my code Behind, I have an event handler and a function to give the path and etc.

    
            void radCarousel_Loaded(object sender, RoutedEventArgs e)  
        
                    {

                        this.radCarousel.ReflectionSettings.Angle = 0;  
        
                        System.Windows.Shapes.Path path = CreateLinePath();  
        
                        if (panel != null)  
        
                        {  
        
                            this.radCarousel.FindCarouselPanel().Path = path;  
        
                            this.radCarousel.FindCarouselPanel().ItemsPerPage = 7;  
        
                        }  
        
                    }  
        
                    private System.Windows.Shapes.Path CreateLinePath()  
        
                    {  
        
                        System.Windows.Shapes.Path newPath = new System.Windows.Shapes.Path();  
        
                        PathFigureCollectionConverter figureConverter = new PathFigureCollectionConverter();  
        
                        object geometryFigures = figureConverter.ConvertFromString("M30,200 L307.5,200");  
        
                        PathGeometry newGeometry = new PathGeometry();

                        return newPath;  
        
                    }

While i'm setting the

this.radCarousel.FindCarouselPanel().Path = path;

this.radCarousel.FindCarouselPanel().ItemsPerPage = 7;
part, FindCarouselPanel() returns null. Yesterday it was working. I didn't changed anything except the Style of radCarousel. Should i be implementing the RadCarouselPanel to style as well?
Please help.

First look at numeric updown

Hi,

I'v taken a look at the progressbar - since I guesd it cood be used as a gauge control in an app I develeope.

By testing it at the samples I found your numeric updown there.
And since it did some "strange" things I went to the numeric up down sample.
At his moment I was hopeing you simply made a miste at the progressbar sample.

So my first exipriences I'm "keyboard oriented" - so i would never click 50 time on an up button to change a value of 20 to 70 :)

First thing - I can't focus the things via TAB - not that problem.

I focus it with the mouse - results very different.
Sometime it marks the whole numer - sometimes not.
Doubleclick does not (as expected) mark the whole field - it stops at the comma seperator.

Anyhow - I can mark it all - draging with the mouse.

Now I expect - everything marked - I type and this will replace the text :)
So I marked the "beta" value (1,14) and type 300.
I get??? YES 0 nothing else.
OK - some hack with focus and so goes on - I go in front of the 0 in the texfield and type 3 --- YES it is there.
Since the 0 is still in the field I see no 30 with the cursor between 3 and 0.
What is missing to get 300? A zero - so type it - the result?
0 - not this time NOT - I get 100 - the 0 goes in and the 3 changes to 1.

YES I found out why - the control is limited to 100.
OK - mark the 100 again (draging the mouse).
Type 99 - and get? 9 - type another 9 and get 99.
Mark all type 12 -- get 2....

OK - I take the value Shares.
I mark all type 321 and get 21 :)
I move the cursor to the front type 3 and get 321.
Ups I like 421 I move the cursor between 4 and 21 hit backspace than 4 and get?
Right - 214 - because hitting the backspace removes the 3 (as it should) and than moves the cursor back to the end of the number (not expected).

I'll stop now - I guess you can play for hours with that thing; alwas getting a funny result.
But you can't use such a thing in a production environment.

Starting from the fact that a marked number is NOT replaced by what you type and ending in setting the value to MAX if you type to much.

Expect you give 1.000.000 as max.
The user types (from a form) 3469738 and than (by mistake) another 0.
He gets? 1000000 -- all the number he did type are gone.

Do this in a normal control - you get Uuuuups a number to big - or it does not accept the last digit since the value is to large.
But forcing the user to retype complex numbers....

Was this control tested only by mouse?
Or did anyone put it on a from - navigate via TAB and enter numbers?
If so - why did nobody see that it "eats" the first number you enter?

Sorry for my anger - but a simple unit test on an input control should include a "replace by entering numbers".
And not doing such a simple test is not a sign of quality!

Regards

Manfred

[Solved] Data trigger not working with dynamically created date picker

I am creating a date picker in my code and want to change its background whenever its value is not valid(specified by IsValidFieldValue flag), but its not working .

Here is my code for creating the control and style :

    
            // Binding to be set for control 
        
            Binding binding = new Binding("Value");

            RadDatePicker datePicker = (RadDatePicker)System.Windows.Markup.XamlReader.Load(stream); 
        
            datePicker.SetBinding(RadDatePicker.SelectedDateProperty, binding); 
        
            datePicker.Style = (Style)FindResource("DatePickerStyle");

Collumn.Width="*" throws Exception

I have a bug when I set the width of a column to * (i.e. take up all remaining space). This works fine if I populate the DataContext before I view the grid (e.g. in the constructor of WPF page) but fails when I populate the DataContext after the grid has been created and laid out (e.g. User choose an item to display in the grid at runtime).

Here is the code need to recreate the problem.

    
            public class DummyObject 
        
                { 
        
                    public DummyObject(string name, string notes) 
        
                    { 
        
                        Name = name; 
        
                        Notes = notes; 
        
                    } 
        
                    public string Name 
        
                    { 
        
                        get; 
        
                        set; 
        
                    } 
        
                    public string Notes 
        
                    { 
        
                        get; 
        
                        set; 
        
                    } 
        
                }
