Hello everyone, now I have put some pinpoints on the map(behind there are some custom objects named target), and I want the image of pinpoint to change dynamically when some events occur, what should I do? Should I Use INotifyPropertyChanged or ObservableCollection (maybe this will not work because map will not refresh when image source property change)? Or should I not use pinpoint and instead use custom item directly?
What's the best way to organize the items on map that can reflect the change of property(image) in real time? Thank you every much and wait for help! (Better If there are some sample codes)

Horizontal Line

It is possible to create a horizontal line in word by entering a long line of dashes and then hitting return. Not only does this not work in the radrichtextbox, but horizontal lines do not appear when copy and pasted or when in an imported richtext document.

First Tab error

We are importing rich text documents into the radrichtextbox (verson 2013.3) and have issues with the first tab. In word, if the first line of a paragraph is outdented, then the first tab on the first line will will take the cursor to the indent point. Right now the first tab takes the cursor to a default tab position which is every half inch. Is this being addressed?

Problem defining a tool-tip in a CellStyle

Good morning,
I am having a problem when using an in-line CellStyle to set a 'condiitonal' ToolTip. The scenario I'm dealing with boils down to a single column where some rows have a tool-tip and others do not. Initially when hovering over a cell with a tool-tip the tool-tip is displayed correctly. I then hover over a cell without a tool-tip and as expected no tool-tip is displayed; however, upon returning to a cell with a tool-tip the tool-tip is no longer displayed correctly. If you repeat the process the tool-tip will alternate between working and not working. Why are the rows with a tool-tip being affected by the rows without? Thanks in advance!

We are currently on the 2013.2 Telerik libraries.

Below is a code sample that illustrates the problem. First is the ViewModel that holds a simple collection of Model objects.

using System.Collections.ObjectModel;

using System.Windows;

namespace ConditionalColumnToolTip

{

public class ViewModel

{

public ViewModel()

{

Models = new ObservableCollection<Model>

{

new Model{ Name = "HasAToolTip", ToolTipVisibility = Visibility.Visible, ToolTipText = "tool tip text"},

new Model{ Name = "NoToolTip", ToolTipVisibility = Visibility.Collapsed },

new Model{ Name = "HasAToolTip", ToolTipVisibility = Visibility.Visible, ToolTipText = "tool tip text"},

};

}

public ObservableCollection<Model> Models

{

get; set;

}

Next is the simple definition of the Model object.

using System.Windows;

namespace ConditionalColumnToolTip

{

public class Model

{

public string Name

{

get; set;

}

public Visibility ToolTipVisibility

{

get; set;

}

public string ToolTipText

{

get; set;

}

I set the DataContext of my MainWindow.xaml to an instance of the ViewModel in the MainWindow.xaml.cs

using System.Windows;

namespace ConditionalColumnToolTip

{

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

DataContext = new ViewModel();

}

And finally here is the XAML for the MainWindow.xaml that recreates the issue.

<Window x:Class="ConditionalColumnToolTip.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

xmlns:vm="clr-namespace:ConditionalColumnToolTip"

xmlns:gridView="clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView"

Title="MainWindow" Height="350" Width="525"

mc:Ignorable="d" d:DataContext="{d:DesignInstance vm:ViewModel, IsDesignTimeCreatable=True}">

<Grid>

<telerik:RadGridView ItemsSource="{Binding Models}" AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="TITLE" DataMemberBinding="{Binding Name}">

<telerik:GridViewColumn.CellStyle>

<Style TargetType="{x:Type gridView:GridViewCell}" BasedOn="{StaticResource {x:Type gridView:GridViewCell}}">

<Setter Property="ToolTip">

<Setter.Value>

<ToolTip Visibility="{Binding ToolTipVisibility}">

<TextBlock Text="{Binding ToolTipText}"/>

</ToolTip>

</Setter.Value>

</Setter>

</Style>

</telerik:GridViewColumn.CellStyle>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>

Any ideas would be greatly appreciated. Thanks again!

Cheers!
Jason

Hide some mail merge fields

Hi,

I have an object which I use in Mail Merge. Under "Insert Mail Merge" drop down ribbon button, all of these fields appear and I can use them just fine. However, I don't need all properties to be displayed there. Is there a way to specify which properties show and should not be included as part of the Mail Merge fields?

Also, is it possible to give a different name to the Mail Merge item in the drop down ribbon button? For example, if I have a property FirstName, I want it to display as "First Name".

Thank you in advance.

specific color for each type of task

I need to be able to color each task on the gantt view independently. meaning the first item in a series should be blue if it meet a criteria, or red, or green, depending on conditions. I only see the theming option, which wont accomplish my goal.
is it possible to color each task seperately?

API naming inconsistent with charting

Some api naming issues that tend to make working with charting more difficult:

RadChart is in the Telerik.Windows.Charting.dll and is referred to as "Chart" in the documentation and RadChart in code.

However, RadChartView is in the Telerik.Windows.Controls.Chart.dll (where you would think to look for RadChart), is referred to in the documentation as "ChartView" and the even less obvious "RadCartesianChart" in code.

I'm sure as new assemblies and controls get created a need for backward compatibility must be maintained, so the Charting.dll reference is likely a product of that since it appears like new controls get added to the Controls namespace. But something should be considered for Chartview, either correcting the code name (which hurts upgrade-ability) or correcting the documentation (which is always a pain).

Also, on a related note, the link in the Chart documentation that says "We encourage you to review our new control RadChartView for super-fast visualization of your data." links back to the Chart documentation instead of the ChartView documentation.
