The RadComboBox seems to require the user to have the cursor over the item text to be able to select the item. This is not the case for the standard ComboBox. Is it possible to change this without creating a custom ControlTemplate?

It is not bad when the items are longer strings. But we have a combo box with individual characters, and you have to click directly on the character to select the item. For whatever reason, if the items in the combo box are integers, selection works as expected.

See the attached animated gif.

In Excel, if you select a row and then drag down past the bottom of what is visible, it scrolls automatically for you. But the RadSpreadsheet does not do this. Is there an option I am missing or an easy workaround?

Hi All,

I am opening RadWindow with ShowDialog() from viewmodel. I am not able to detect close 'X' button event. I want to prompt user before closing. 

My code looks like:

AssetViewModel.cs

var AssetWindow = new RadWindow
            {
                Header = "Asset Information",
                Owner = Application.Current.MainWindow,                
                WindowStartupLocation = System.Windows.WindowStartupLocation.CenterOwner,
                Content = new UserControl()
            };          
AssetWindow.ShowDialog();

What is the best approach to detect close event, prompt user and proceed with user selected option i.e Yes/No

 Any help would be appreciated,

Regards,

Hi All,

I am using RadTabControl and validation is working only if tab is selected. i.e. updating UI only for selected tab and not others.

I have a RadTabControl control with three RadTabItem. Every tabitem contains usercontrol with own view model.

For all user controls, i have used  IDataErrorInfo for validation. From main control, manually i am triggering validation using notifyproperty change i.e.  RaisePropertyChanged(string.Empty).

This is working fine only if tab is selected. validation is executing properly on other tabs but UI is not updating. 

Control Structure:

MainVM.cs

      - TabControl1VM = new TabControl1ViewModel();

      - TabControl2.VM = new TabControl2ViewModel();

 

MainControl.xaml

  <telerik:RadTabControl  >
            <telerik:RadTabItem  Header="Location" DataContext="{Binding TabControl1VM}" >
                <telerik:RadTabItem.Content >                    
                        <local:TabControl1></local:TabControl1>                    
                </telerik:RadTabItem.Content>
            </telerik:RadTabItem>

            <telerik:RadTabItem Header="Asset Type" DataContext="{Binding TabControl2VM}">
                <telerik:RadTabItem.Content>
                    <local:TabControl2></local:TabControl2>
                </telerik:RadTabItem.Content>
            </telerik:RadTabItem>

 

Any help would be appreciated,

Regards,

Hi,

I'm looking for a way to bind a List of key / value objects to the propertygrid. Consider the following snippets of code:

public class MyKeyValueClass

{

    public string Key {get;set;}

    public string Value {get;set;}

}

I tried something like this:
XAML:


.cs:




This sets the displaynames accordingly, but won't show / bind the values 
Is this possible?

I am currently trying to Drag Drop Custom Control from List box to RadDiagram.

I am able to Drag the Custom Control (Shell) but not able to Create a Shape in RadDiagram.

Code:

Shell (Custom Control)

 public class Shell : Telerik.Windows.Controls.Diagrams.RadDiagramShapeBase
    {
        static Shell()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(Shell), new FrameworkPropertyMetadata(typeof(Shell)));
        }
    }

Style
<Style TargetType="{x:Type local:Shell}">
        <Setter Property="BorderThickness" Value="2"/>
        <Setter Property="BorderBrush" Value="Black"/>
        <Setter Property="HorizontalAlignment" Value="Center"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="Height" Value="100"/>
        <Setter Property="Width" Value="100"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:Shell}">
                    <Grid Background="{TemplateBinding Background}">
                        <Ellipse Stroke="{TemplateBinding BorderBrush}"/>
                        <Ellipse  Margin="13" Stroke="Black" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Drag And Drop Code

Telerik.Windows.DragDrop.DragDropManager.AddDragInitializeHandler(listBox, OnDragInitialize);  (ListBox)
Telerik.Windows.DragDrop.DragDropManager.AddDropHandler(radDiagram, OnDropShape);(RadDiagram)

 private void OnDropShape(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
        {
            e.Handled = true;
            Shell shape = new Shell();
            var rawdata= (e.Data as DataObject).GetData(typeof(Shell));
            
           
            {
                Shell droppedShape = rawdata as Shell;
               
                this.radDiagram.AddShape(droppedShape);
           
            }
            
        }

        private void OnDragInitialize(object sender,Telerik.Windows.DragDrop.DragInitializeEventArgs e)
        {
            e.AllowedEffects = DragDropEffects.All;
           Shell draggedshape = (e.OriginalSource as ListBoxItem).Content as Shell;
           e.Data = draggedshape;
            
        }
 I am able to get the dragged Shell but i don`t know how to convert the Shell object to RadDiagramShape.

Any help is appreciated!!!

Can anyone help me?

Hi,

I would like to customise the animation for the opening and navigate event/state of the radial menu. How can I do it? Thank you! 

I have an existing WPF application which uses Microsoft.Windows.controls.Datagrid. I want to add the RadDataPager to do the pagination, how can I do it? 

Here's my sample code. It displays the data but it doesn't do the pagination. All data is displayed in a single page.

<dg:DataGrid Name="dgRegistryDetails" FontSize="14" DockPanel.Dock="Bottom" Foreground="#FF07315B"

                         ItemsSource="{Binding}"   CanUserSortColumns="true"
IsReadOnly="True"    AutoGenerateColumns="False" >

 

<telerik:RadDataPager VerticalAlignment="Bottom" DisplayMode="FirstLastPreviousNextNumeric" Source="{Binding Items, ElementName=dgRegistryDetails}"  IsTotalItemCountFixed="True" x:Name="RadPager" PageSize="10" />

I have a C# WPF application using MVVM with a simple RadCartesianChart that shows a single ScatterLineSeries representing a surface profile.  It works well. 

Now I want to enable my user to mark out certain horizontal regions of the plot for use in my application.  The general idea is this

1. User clicks a button that adds a visual indicator representing the region. 
2. The indicator appears.  It looks like a big wide bar going from the bottom Y of the plot to the top Y and covering an arbitrary X width.
3. The user can then use the mouse (or their finger) to made the bar wider/narrower or move it left or right across the plot

(I have attached an image showing roughly what this should look like.  It is from a much older version of this application that doesn't use C#, WPF or Telerik.)

My problem is not in writing interaction/manipulation code.  It is in determining exactly what Telerik entity I should interact with.  That is I don't know how best to achieve this with the tools Telerik gives me.   

I can think of several approaches. 

• For example, I looked into using Chart Annotations.   They seem perfect for marking out chart regions and your examples are good.  But I can't find any examples that show me how the user might *interact* with them.    How do I add a mouse/touch handler for an annotation?   Is it possible?  Is that the best way?
• Or maybe I should add mouse/touch handlers for the RadCartesianChart object.  Then in code-behind I could try to figure out what annotation my mouse/finger is over and go from there, is that the way?  
• Or should I instead try to create my own buttons, completely separate from the cahrt that overlay the whole plot and match up exactly with chart plot area.  Is that the way to go?
• Is there some other, cleaner way to achieve this?

 

My Chart in XAML is like this:

   

My ProfileRegionVm class -- which represents an instance of this horizontal reagion is like this:
