I use the chart to display some data, but the labels can become very long.
Now I want to use the Default LabelFormat but I do not seem to get it work

I use the following #LABEL{[a-zA-Z]{0,10}...}

But my string always stays as long as it is. I want the string to be a max of 15 chars and if longer have the tree dots after it

DataSet and SelectedItem Problem

I need to get the value of the selectedItem NumeroIncidencia column, I looked at the examples and following the steps that detail does not work, I can help.

Thank you.

Group Aggregated Functions Caption

Hello,
I'm having troubles with the aggregate functions. On the examples that I have found when you group a column the collapsed row has whatever caption is on the GroupFooters and they seem to be left justified.
on the one I'm working with they display but they seem to be pushed to the right. I can't seem to find a way to position them to the left.

    
            <telerik:RadGridView

How do I get the RadTreeViewItem if I'm using HierarchicalDataTemplate?

I have a RadTreeView with HierarchicalDataTemplate as follows:

    
            <HierarchicalDataTemplate DataType="Category" ItemsSource="{Binding XPath=Category}"> 
        
               <TextBlock x:Name="tbCategoryName" Text="{Binding XPath=@Name}" MouseRightButtonUp="tbCategoryName_MouseRightButtonUp" 
        
                                       MouseDown="tbCategoryName_MouseDown"> 
        
               </TextBlock> 
        
            </HierarchicalDataTemplate>

I need access to the RadTreeViewItem so that I can call methods and properties such as BeginEdit, ExpandAll, and IsExpanded.
This is my RadTreeView declaration:

    
                    <telerik:RadTreeView ItemsSource="{Binding Source={StaticResource CategoriesXML}}" Margin="105,64,0,0"  
        
                                         Name="tvOntology" HorizontalAlignment="Left" VerticalAlignment="Top" Width="200" 
        
                                         IsEditable="True" IsEnabled="True" IsExpandOnDblClickEnabled="False"  
        
                                         IsExpandOnSingleClickEnabled="True"> 
        
                    </telerik:RadTreeView>

It works fine but I'm not able to get the RadTreeViewItem. Could someone tell me how, please?

Grouping of a column with a converter

Hello,
I encountered a problem with the GridView WPF-Control. When I use a Converter in the DataMemberBinding of a column and group by that column, the result will be grouped by the unconverted value.

To show the problem, i set up a small test project with a small "Person" class with "Name" (string), "Age" (int) and "Status" (int) properties.
In the test project, three persons-objects will be created and bound to a GridView. Each property in a seperate column.
The "Status" column uses a converter for the DataMemberBinding:

    
            <Window x:Class="RadGridViewColumnTest.Window1" 
        
                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" 
        
                xmlns:System="clr-namespace:System;assembly=mscorlib"         
        
                xmlns:local="clr-namespace:RadGridViewColumnTest" 
        
                Title="Window1" Height="300" Width="300"> 
        
                <Grid> 
        
                    <Grid.Resources> 
        
                        <local:StatusConverter x:Key="StatusConverterResource"> 
        
                        </local:StatusConverter> 
        
                    </Grid.Resources> 
        
                    <telerik:RadGridView x:Name="grid" AutoGenerateColumns="False" Grouping="grid_Grouping"> 
        
                        <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewDataColumn HeaderText="Person" DataMemberBinding="{Binding .Name}" DataType="{x:Type System:String}"> 
        
                            </telerik:GridViewDataColumn> 
        
                            <telerik:GridViewDataColumn HeaderText="Age" DataMemberBinding="{Binding .Age}" DataType="{x:Type System:Int32}"/> 
        
                            <telerik:GridViewDataColumn HeaderText="Status" DataMemberBinding="{Binding  Path=Status, Converter={StaticResource StatusConverterResource}}" IsSortable="True" DataType="{x:Type System:Int32}" IsGroupable="True"/> 
        
                        </telerik:RadGridView.Columns> 
        
                    </telerik:RadGridView> 
        
                </Grid> 
        
            </Window>

    
            public class StatusConverter : IValueConverter 
        
                { 
        
                    #region IValueConverter Members 
        
                    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
        
                    { 
        
                        if ((int)value < 256) 
        
                        { 
        
                            return "< 256"; 
        
                        } 
        
                        else 
        
                            return ">= 256"; 
        
                    } 
        
                    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 
        
                    { 
        
                        throw new NotImplementedException(); 
        
                    } 
        
                    #endregion 
        
                }

The Status of the three persons are 122, 123, 321, and they appear correctly converted in the list.
Obviously the result, after a group by Status, should show the persons with Status 123 and 123 in one group because their Status is below 256.
But it seems the converter won't be used for grouping and every person appear in a single group.
Is there a solution for this problem ?

Thanks, Michael

New Row with "Interface-Bound" GridView

Hi.
I am looking for "the right way" to add new Rows to a GridView...
1. Is there any pre-defined method to add new rows ? (Like the WinForms MS-Grid used to have...)
Something like:

    
            AddNewRowIfUserDoubleClicksTheLeftPane="true"

2. I am displaying some navigateable Properties which are based on Types of which I know the Interface only..
Something Like:

    
            public class DisplayData  
        
            {  
        
               public string Name { get; set; }  
        
               public ISomeInterfaceType Prop { get; set; }  
        
            }  
        
            public interface ISomeInterfaceType  
        
            {  
        
               string OtherName { get; }  
        
            }

    
            <telerik:GridViewDataColumn     
        
                 Header="Name"    
        
                 DataMemberBinding="{Binding Path=Name, Mode=OneWay}"    
        
                 Width="2*"    
        
                 IsReadOnly="True"/>    
        
            <telerik:GridViewDataColumn     
        
                 Header="Other"    
        
                 DataMemberBinding="{Binding Path=Prop.OtherName, Mode=OneWay}"  
        
                 DataType="{x:Type sys:String}"  
        
                 Width="3*"    
        
                 IsReadOnly="True"/>

However, I want to be able to let the user add new rows - in which case I need two entered strings (which I check for validity) and afterwards return the new "DisplayData"-Object. Currently I am doing this using a new Window (ShowDialog()) which let's the User input his data...

Can I use the "new-row" feature of the GridView, if some columns are bound to read-only properties or even classes of which I know only the Interface ?

Yours,
Nils
