how can I specify MultipleSelectionBoxTemplate which i can access properties of selected items ?

i have an employee class 

    public class Employee {
    public string Firstname {get;set;}
    public string Lastname {get;set;}
    }

I am using Telerik radCombobox in my wpf application to display list of employee 

              <telerik:RadComboBox x:Name="radComboBox"
                                     Width="200" 
                                     AllowMultipleSelection="True" 
                                     ItemsSource="{Binding Path=EmployeeList}"  
                                     >

                    <telerik:RadComboBox.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=Lastname}" />
                        </DataTemplate>
                    </telerik:RadComboBox.ItemTemplate>

note: this code simplified , i have to use ItemTemplate  because i set textblock style based on some condition 

this works fine for item template  but when i select an item the display text in combobox show  full name of Employee class (namespace + class name ) not the Lastname
i tried 

             <telerik:RadComboBox.MultipleSelectionBoxTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=Lastname}" />
                        </DataTemplate>
                    </telerik:RadComboBox.MultipleSelectionBoxTemplate>

i get no result , the combobox displayvalue of selected item is always empty.

i tried another solution 

                    <telerik:RadComboBox.MultipleSelectionBoxTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Path=SelectedItems,Converter={StaticResource SelectionToCustomStringCoverter}}" />
                        </DataTemplate>
                    </telerik:RadComboBox.MultipleSelectionBoxTemplate>

this neither work , the converter always execute at first selection 

this is really crazy spending 4 hours to figure out a simple thing , 
so my question is how can i specify MultipleSelectionBoxTemplate which i can access properties of selected items .

Hello, 

Using the DiagramDesignToolBox_WPF project diagram control (from Telerik's github) samples, I created a basic diagram. See attached.

Once the diagram is loaded, is it possible to associate commands such as click, be able to update the diagram object's background color, be able to update the diagram object's text, etc.?

Thanks,

Mark

One last question:

My Telerik subscription provides me with X support tickets per year but I can't find where to create a new support ticket. I see my past tickets that I've created but no where can I start a new one. How can I start a 'priority' question that is associated with my paid Telerik subscription?

I have cells highlighted by changing cell' foreground color.

Now i need to collect those highlighted cells to select cells programmatically. I can browse through values but need to read back cell style:

List<GridViewCellInfo> highlightedCells = new List<GridViewCellInfo>();
foreach (var item in this.gridView.Items)
{
     foreach (var column in this.gridView.Columns.OfType<GridViewBoundColumnBase>())
     {
          var cell = column.GetValueForItem(item); // it is actual cell value
// looking for something like: 
// if (cell.Foreground == Brushes.Cyan)
//       highlightedCells.Add(cell)
     }
}

Hi

I am having an issue binding the IsSelected property of a RadListboxItem. Specifically I am attempting to follow the pattern provided in this blog post Accessing WPF ListBox SelectedItems using MVVM (markwithall.com)

The key part toward the bottom of the post is this which binds the IsSelected property of a ListBoxItem. I have tested it and it works just fine.

<ListBox ItemsSource="{Binding Items}" SelectionMode="Extended">
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="IsSelected" Value="{Binding IsSelected}" />
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

However when I try to use a RadListbox and setup the ItemContainerStyle like this

<telerik:RadListBox.ItemContainerStyle>
	<Style TargetType="telerik:RadListBoxItem" BasedOn="{StaticResource RadListBoxItemStyle}">
		<Setter Property="IsSelected" Value="{Binding IsSelected}" />
	</Style>
</telerik:RadListBox.ItemContainerStyle>

Hello,

I have an issue concerning GridViewDataColumn. Currently, my data type is Enum. If I sort it in my RadGridView (click on the header of this column) the view is empty after my click, and every data disappear. With other fields it's working fine (string, int, etc..)

Here's how I create my Column:

<telerik:GridViewDataColumn                         
    Header="Type" UniqueName="MyType"
    DataMemberBinding="{Binding Type}"
    IsSortable="True" IsFilterable="False" IsResizable="True"
    TextAlignment="Left" HeaderTextAlignment="Center" />

It doesn't look possible to sort Enum in this field. Someone has a solution or can help me to make a custom sort for this column?
If you need something more, feel free to ask ;)

Hello, 

I need to create a scale, showing the Major tick at the beginning/at the end of the scale.

In order to do this, I've set ShowLastLabel to false. The data on the scale changes every 200 m/s.  The last label sometimes blinks, even though the property ShowLastLabel is set to false.

If I change EndTickOffset, instead of changing ShowLastLabel, then I do not see the Major tick at the end of the scale.

See the attached example.

 <telerik:RadVerticalLinearGauge 
             FontSize="16"
             Background="Green"
             HorizontalAlignment="Left"
             Width="3"
             Margin="30,94,0,95"
            >
            <telerik:VerticalLinearScale
                    Max="{Binding Max,FallbackValue=20}"
                    Min="{Binding Min,FallbackValue=0}"
                    Background="Green"
                    LabelLocation="Inside"
                    FontSize="16"
                    StartTickOffset="{Binding TickOffset,FallbackValue=0}"
                    EndTickOffset="{Binding TickOffset,FallbackValue=0}"
                 ShowFirstLabel="False"
                    ShowLastLabel="False"
                    MajorTickStep="10"
                    IsInteractive="True"
                    MinorTickBackground="Red"
                    MiddleTicks="2"
                    MiddleTickBackground="Green"
                    MiddleTickLocation="Outside"
                    LabelOffset="16"
                    MiddleTickRelativeWidth="5"
                    MiddleTickRelativeHeight="0.015*"
                    MajorTickRelativeWidth="20"
                    MajorTickRelativeHeight="0.015"
                    EndWidth="0.03"
                    StartWidth="0.03"
                    MinorTicks="1"
                    >
            </telerik:VerticalLinearScale>
        </telerik:RadVerticalLinearGauge>

Hi, I am trying to display some glyphs in my WPF application using the RadGlyph control.

Unfortunately some of them are not displayed and I do not understand why.

I am usig the 2021 R3 version and .Net Framework 4.7.2.

I am attaching a sample where this issue can be easily reproduced.

Thanks for the help.

Hi,

I use RadGridView.ExportToWorkbook on a grid with over 600 000 rows: the operation take much than 5' to end. Can I speed up it?

Thank you
