I have what I believe should be a simple problem, my legend items are just showing up as item0 - item6. I need them to show up with the name of the object in my items from the database.

I'm using a dataset to link to SQL, my 2 fields in my dataset are "sales" and "productclass".
I'm not sure what I missed, I followed the examples from the legend section exactly I think.

thanks for any help you can provide.

I working on an app where I would like to have a Window with a single TabControl and a single RadDocking control in each one of its TabItems.  This works as long as the docking control is the content of the TabItem control.  As soon as something comes in between the two (such as the Grid control in the sample code), the exception below is thrown.  Do you know if this scenario is possible?  I'm using 2010 Q1.
    
    <TabControl> 
        <TabItem Header="Foo"
            <Grid> 
                <td:RadDocking /> 
            </Grid> 
        </TabItem> 
        <TabItem Header="Bar"
            <Grid> 
                <td:RadDocking /> 
            </Grid> 
        </TabItem> 
    </TabControl> 

System.InvalidOperationException: Specified element is already the logical child of another element. Disconnect it first.

I've noticed that when I add drag and drop to a grid the column sizing no loger works.

I have implemented the drag/drop events..

        private void OnDropQuery(object sender, DragDropQueryEventArgs e)
        {

            Type sourceType = e.Options.Source.GetType();
            if (sourceType == typeof(GridViewHeaderCell))
            {
                return;
            }
        .
        .
        .

and
        #region dragQuery
        protected virtual void OnDragQuery(object sender, DragDropQueryEventArgs e)
        {
            if (sourceType == typeof(GridViewHeaderCell))
            {
                e.QueryResult = true;
            }
        .
        .
        .

How should the drag and drop respond to the GridViewHeader?

Hi,
I have typed the following text in Google-translator, so it goes faster, so please excuse any errors.
I have the following problem with the WPF RadWindows:
Whenever it opens, is thrown a System.ArgumentException. Whether it's own window, or create the controls of their choice.
The windows are always at the upper corner of the screen. If I want to move the window, thrown the exception.
Here is a screenshot of a window of RadShedule: http://img1.bildupload.com/4ed9dbb35ad45e65eb4bc6814fa455cf.jpg and as attachment.

I searched for this error (google and Telerik) and have found several entries. Unfortunately, none has been solved so far.
I've tried the following workarounds:
1. Catch the ecxeption in app_DispatcherUnhandledException does work, but the application also crashes after short time (when moving), so no solution
2. refer to this thread: http://www.telerik.com/community/forums/silverlight/gridview/radgridview-exception-onclose-of-radwindow.aspx: still no solution
3. i found this: http://www.telerik.com/community/forums/silverlight/window/exception-value-does-not-fall-within-the-expected-range-when-displaying-nested-rad-windows.aspx, but there is also no solution, only a reference at the HACKS class (but this is still private, perhaps in the internal user) you.

I'm desperate, I can indeed use for my own window, the standard Window class, but all of the windows, for example RadShedule are RadWindows.
The error also appears in your wpf example application. (detailed see screenshots):

http://img1.bildupload.com/1c6f66118fa997a217583dbfeb422b91.jpg
http://img1.bildupload.com/b5d4ab2f5cdc6b38f735a9cc0f21c441.jpg

But...,
in Silverlight the moving, resizing and closing and reopening of the window works with no problems: http://img1.bildupload.com/60332521dc5deec8783c99ae08dc5f84.jpg


I would like to thank you very much if you could deal with the problem, since all other contributions were offered no further assistance or solutions. I can send you all important project data, unless you can reproduce the problem.
Can it possibly be constellation problem with my system. If you suspect this, I send you also necessary system parameters (os: Vista Ultimate 64-bit video card: NVIDIA 9800 SLI (2 units) and so on)

Many many thanks in advance.

Hi

Just thought I'd make a suggestion for a new WPF control.

I not sure if there's a name for it already but basically its kind of a spinning progress indicator, to show the user that something is happening but it doesn't actually show progress. Like if you were loading data to the UI.

The best example I can think of is in Firefox when its loading a website. In the tab, there's a small circle of circles and each circle flashes around the main circle, whilst the page is being loaded.

I've already created something similar but it took me ages to get the animation (see attached).

Just being able to drop the control and set a few animation properties would have saved me several days work.

I think it would be popular.

Hi,

I have a carousel on a WPF page and it seems the Height of the CarouselItem does not allow me to set it above about 300 pixels.  See my attached screen shot A and B. 

I am setting the CarouselItem template using the following XAML:
       <Style TargetType="{x:Type telerik:CarouselItem}">  
            <Style.Resources> 
                <loc:StaleTagValueConverter x:Key="TagStateConverter" /> 
            </Style.Resources> 
            <Setter Property="Width" Value="400" /> 
 
            <Setter Property="Template" > 
                <Setter.Value> 
                    <ControlTemplate TargetType="{x:Type telerik:CarouselItem}" > 
 
                        <Border BorderBrush="Black" BorderThickness="1"  VerticalAlignment="Stretch"  CornerRadius="8" d:IsHidden="False">  
                            <Border.Background> 
                                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">  
                                    <GradientStop Color="#FF38A4DE" Offset="1"/>  
                                    <GradientStop Color="#FFC4E9F8"/>  
                                </LinearGradientBrush> 
                            </Border.Background> 
                            <Grid Margin="7" d:IsHidden="False">  
                                <Grid.ColumnDefinitions> 
                                    <ColumnDefinition Width="0.415*"/>  
                                    <ColumnDefinition Width="0.585*"/>  
                                </Grid.ColumnDefinitions> 
                                <Grid.RowDefinitions> 
                                    <RowDefinition Height="0.768*"/>  
                                    <RowDefinition Height="0.232*"/>  
                                </Grid.RowDefinitions> 
                                <Border BorderThickness="1" Margin="0,0,0,8" Background="White" CornerRadius="0,0,3,3" Grid.ColumnSpan="2" d:IsHidden="False">  
                                    <Grid Margin="7" d:IsHidden="False">  
                                        <Grid.ColumnDefinitions> 
                                            <ColumnDefinition Width="0.542*"/>

                                        </Grid.ColumnDefinitions> 
                                        <Image Margin="8,7,4,8" Source="/Styles/Resources/circuit.jpg" Stretch="Fill" d:IsHidden="False"/>  
                                        <StackPanel Grid.Column="1" Margin="8,4,0,4" d:IsHidden="False">  
                                            <TextBlock Height="45" Margin="0" Style="{DynamicResource BasicTextBlock-Normal}" Foreground="Black" d:IsHidden="False"><Run Foreground="Gray" Text="Bin Location"/><LineBreak/><Run Text="Warehouse 1"/></TextBlock> 
                                            <TextBlock Height="45" Margin="0,2,0,0" Style="{DynamicResource BasicTextBlock-Normal}" Foreground="Black" d:IsHidden="False"><Run Foreground="Gray" Text="Item"/><LineBreak/><Run Text="0101-0028"/></TextBlock> 
                                            <TextBlock Height="45" Margin="0,2,0,0" Style="{DynamicResource BasicTextBlock-Normal}" Foreground="Black" d:IsHidden="False"><Run Foreground="Gray" Text="Serial"/><LineBreak/><Run Text="BABEFF01"/></TextBlock> 
                                        </StackPanel> 
                                    </Grid> 
                                </Border> 
                                <Image Margin="4" Grid.Row="1" Source="/Styles/Resources/barcode_black.png" Stretch="Fill" Height="20" VerticalAlignment="Top" Grid.Column="1" HorizontalAlignment="Left" Width="170" d:IsHidden="False"/>  
                                <TextBlock Margin="8,32,8,8" Grid.Row="1" Style="{DynamicResource BasicTextBlock-Normal}" Text="E2000900002005011523602991" Foreground="Black" Grid.ColumnSpan="2" d:LayoutOverrides="HorizontalAlignment" TextAlignment="Center" d:IsHidden="False"/>  
                            </Grid> 
                        </Border> 
 
                    </ControlTemplate> 
                </Setter.Value> 
            </Setter> 
 
 
        </Style> 

Even if I set the Height property with this:

       <Style TargetType="{x:Type telerik:CarouselItem}">  
            <Style.Resources> 
                <loc:StaleTagValueConverter x:Key="TagStateConverter" /> 
            </Style.Resources> 
            <Setter Property="Width" Value="400" /> 
            <Setter Property="Height" Value="450" /> 
            <Setter Property="Template" > 
And set the main border inside the control template to this:
<Setter Property="Template" > 
                <Setter.Value> 
                    <ControlTemplate TargetType="{x:Type telerik:CarouselItem}" > 
 
                        <Border BorderBrush="Black" BorderThickness="1"  VerticalAlignment="Stretch"  CornerRadius="8" d:IsHidden="False" Height="400">  
                            <Border.Background> 
                                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">  
                                    <GradientStop Color="#FF38A4DE" Offset="1"/> 

It still clips the content to what appears to be somewhere between 250 and 300 pixels. 

How can I make the content template height larger to fit my content?

Thanks,
David Sandor

Hello!

I'm not sure what I'm missing here.
I have a RadGridView with the following structure:

            <Controls:RadGridView x:Name="radGridView" 
                                  ScrollMode="RealTime" 
                                  ShowGroupPanel="False" 
                                  CanUserReorderColumns="False" 
                                  CanUserDeleteRows="False" 
                                  CanUserInsertRows="False" 
                                  Grid.Row="1" 
                                  ItemsSource="{Binding Metadata}" 
                                  AutoGenerateColumns="False" 
                                  ShipMonitoring:DataInfoHeaderMenu.IsEnabled="True"
                <Controls:RadGridView.Columns> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Name}" 
                                                 Header="Symbol" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding ClearName}" 
                                                 Header="Name" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Description}" 
                                                 Header="Description" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Source}" 
                                                 Header="Source" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Unit}" 
                                                 Header="Unit" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Category}" 
                                                 Header="Category" 
                                                 IsReadOnly="True" /> 
                    <Controls:GridViewDataColumn Header="Select " 
                                                 IsReadOnly="True" 
                                                 DataMemberBinding="{Binding Used}"
                        <Controls:GridViewDataColumn.CellTemplate> 
                            <DataTemplate> 
                                <CheckBox IsChecked="{Binding Used, Mode=TwoWay}" 
                                          HorizontalAlignment="Center" 
                                          Checked="DataInfo_CheckedUnchecked" 
                                          Unchecked="DataInfo_CheckedUnchecked" /> 
                            </DataTemplate> 
                        </Controls:GridViewDataColumn.CellTemplate> 
                    </Controls:GridViewDataColumn> 
                </Controls:RadGridView.Columns> 
 
            </Controls:RadGridView> 


the "Metadata" from binding represents a List<Metadata> where Metadata object has this "Used" field represented by a checkbox.
In DataInfoHeaderMenu I can choose to select or deselect all rows in the radGridView 
I retrieve the metadata list from grid view 
(List<Metadata>)radGridView , I iterate over it and set for each object Used = true.

the problem is that this should have as a result all check-boxes checked but id doesn't!

Please help!

Hi, 
we updated to Telerik 2010 Q1 Beta, and now we can drag the floating window outside of the main window, but we no longer can drag and drop from one floating window into another or into the main window.
What should we do to make the drag and drop work between the windows.
Thanks
Nick
