I've noticed that there are some differences between several controls regarding watermark styling and left padding. It becomes quite visible if you put them next to each other. The left column only contains watermarkcontent and the right one contains text. I'm using the Windows7Theme but it looks the same in several other themes aswell.

 

<StackPanel Orientation="Horizontal">
    <StackPanel Width="200" HorizontalAlignment="Left">
        <telerik:RadWatermarkTextBox Margin="3" WatermarkContent="RadWatermarkTextBox"/>
        <telerik:RadAutoCompleteBox Margin="3" WatermarkContent="RadAutoCompleteBox"/>
        <telerik:RadMaskedTextInput HorizontalAlignment="Stretch" Margin="3" EmptyContent="RadMaskedTextInput" TextMode="PlainText"/>
        <telerik:RadComboBox IsEditable="True" Margin="3" EmptyText="RadComboBox"/>
    </StackPanel>
    <StackPanel Width="200" HorizontalAlignment="Left">
        <telerik:RadWatermarkTextBox Margin="3" Text="RadWatermarkTextBox"/>
        <telerik:RadAutoCompleteBox Margin="3" SearchText="RadAutoCompleteBox"/>
        <telerik:RadMaskedTextInput HorizontalAlignment="Stretch" Margin="3" Value="RadMaskedTextInput" TextMode="PlainText"/>
        <telerik:RadComboBox IsEditable="True" Margin="3" Text="RadComboBox"/>
    </StackPanel>
</StackPanel>

I'm developing a bar chart where when the label is selected I need to set the color of that label as well as call an event handler (a different one than what I have set up for the bar selection).

Is there a property that enables this, similar to the ChartSelectionBehavior? Starting with one of the examples I found (see XAML below) I've been able to get the bar selection working and I made the label change color on mouse over, but this isn't what I need - it needs to function more like the bar selection.

Hello,

dnd between two gridviews is not working since the upgrade from 2016.3.914.45 to 2016.3.1024.45.

In the OnDragInitialize methode I'm assigning a DnD object to eventargs.Data which is not recognized by the drop table "eventargs.Data.GetDataPresent()".
It worked perfectly in the previous version but caused yesterday a lot of trouble after upgrading an application to the latest version :(

 

        private void OnDragInitialize(object sender, Telerik.Windows.DragDrop.DragInitializeEventArgs ea) {
            string displayText = "";
            var selectedRows = ((RadGridView)sender).SelectedItems;
            if (selectedRows.Count == 0) {
                return;
            }

            var list = new List<PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO>();
            foreach (PsCore.Interfaces.IDndDataObject row in selectedRows) {
                list.Add(new PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO(row.PrimaryID, row.DisplayText));
                displayText = row.DisplayText;
            }
            ea.Data = new PsCore.DataObjects.DragAndDrop.DndContainerDO<PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO>(list, displayText);

            ea.DragVisual = new ContentControl { ContentTemplate = LayoutRoot.Resources["DraggedItemTemplate"] as DataTemplate, Content = ea.Data };
            this.dragVisualTemp = ea.DragVisual;
            ea.DragVisualOffset = new Point(ea.RelativeStartPoint.X, ea.RelativeStartPoint.Y - 20);
            ea.AllowedEffects = DragDropEffects.All;
            ea.Handled = true;
        }



        private bool IsDndObjectAllowed(DragEventArgs ea) {
            Type dndContainerType = typeof(DndContainerDO<BusinessPartnerEntityDndDO>);
            if (!ea.Data.GetDataPresent(dndContainerType)) {
                Console.WriteLine("DND object NOT recognized");
                return false;
            }
            var draggedData = (ea.Data as DataObject).GetData(dndContainerType) as DndContainerDO<BusinessPartnerEntityDndDO>;
            if ((draggedData != null) && (draggedData.Items.GetType() == typeof(List<BusinessPartnerEntityDndDO>))) {
                return true;
            }
            return false;
        }

Best Regards,

Raul

StyleManager.ApplicationTheme = new TransparentTheme();

Office_Black, Office_Blue, Office_Silver, Expression_Dark, Summer, Vista, Windows 7, Transparent, Windows8, Windows8Touch.

My version is 2012.1.326.40

Hello,

i am trying to implement a command (LeftDoubleClick) from my view to viewmodel using mvvm pattern (without code behind and event).

I saw some samples but they don't work for me!

Please can someone tell me i i am making wrong?

xaml:

<telerik:RadGridView x:Name="radGridView" Margin="8" ItemsSource="{Binding Source={StaticResource DataSource}}"
   IsReadOnly="True"   >
 
        <telerik:RadGridView.InputBindings>
            <MouseBinding Gesture="LeftDoubleClick" helpers:AttachedMouseBinding.Command="{Binding Path=DoubleClickCommand}" />
        </telerik:RadGridView.InputBindings>
 
    </telerik:RadGridView>

 

.cs:

public class UC_SEGridViewModel : InterfaceDescription.ViewModels.ViewModelBase
{
    private ViewModelMaster viewModelMaster;
    public ICommand DoubleClickCommand { get; set; }
 
    public UC_SEGridViewModel()
    {
        DoubleClickCommand = new RelayCommand(GridItemDoubleClick);
    }
 
    private void GridItemDoubleClick(object obj)
    {
        //do something
    }
}

but i don't reach my callback method (GridItemDoubleClick) when i set a breackpoint

the helper:

public class AttachedMouseBinding
    {
        const string PROPERTYNAMECOMMAND = "Command";
 
        public static readonly DependencyProperty CommandProperty = DependencyProperty.RegisterAttached(PROPERTYNAMECOMMAND, typeof(ICommand),
            typeof(AttachedMouseBinding), new FrameworkPropertyMetadata(CommandChanged));
 
        private static void CommandChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            FrameworkElement fe = d as FrameworkElement;
             
            ICommand command = e.NewValue as ICommand;
 
            InputBinding inputBinding = new InputBinding(command, new MouseGesture(MouseAction.LeftDoubleClick));
            fe.InputBindings.Add(inputBinding);
 
            //if (inputBinding != null)
            //    inputBinding.Command = command;
        }
 
        public static ICommand GetCommand(DependencyObject obj)
        {
            return (ICommand)obj.GetValue(CommandProperty);
        }
 
        public static void SetCommand(DependencyObject obj,ICommand value)
        {
            obj.SetValue(CommandProperty, value);
        }            
    }

 

Thanks for your help,

Richard

Hi,

I have a usercontrol which is set IsEnabled = "False". Hence the RadGridView in the usercontrol will be light grey color. I had set the some of the cell to be in red color. Is there any way to avoid grey color for RadGridView when usercontrol is disabled.

Thanks.

Hi,

Is there any simple way to make whole RadGridView transparent?

I mean Headers, Rows, Vertical and Horizontal scrollbars, etc.

Setting "Background" property sets only data row area where no rows are created.

I am using 2015 Q3.

Thanks,

Łukasz

Hi,

on a form I have a pdfviewer and I need to know where the user click on my pdf. The coordinates should be relative to the document not the all radpdfviewer area.

When I get the coordinate with iTextSharp I'll put some image on that area (this part I'm already able to do it)

 

Those are the possibilities that I thought:

- Select an area on pdfviewer and get the coordinates? (THIS ONE WOULD BE THE BEST)

OR

- get the text selection position (I took a look to the documentation but I'm not able do reproduce the example.. this.PdfViewer.Document.CaretPosition is missing)

 

Any other idea?

 

Thank you
