Intellisense in Visual Studio for some reason isn't picking up telerik RadGridView and won't resolve.

My project is targeting .NET 3.5 and has the following references:

`Telerik.Windows.Controls`

`Telerik.Windows.Controls.GridView`

`Telerik.Windows.Controls.Input`

`Telerik.Windows.Data`

All of these are for .NET 3.5 and have a runtime version of 2.0.X

My code:

<Window x:Class="Project.MainWindow"
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"
Title="MainWindow" Height="350" Width="525">

<Grid Loaded="Grid_Loaded">
<StackPanel>
<telerik:RadGridView></telerik:RadGridView> <-- this won't resolve

Any ideas why this is happening and how to fix it?

RadRichTextBox unuexpected behaviour

Hello,

I'm not sure if this is a bug or if it is intended to happen like this, but for some reason, if I try to add text to a RadRichTextBox after a window has finished loading, the rich text box behaves in an unexpected manner: it adds an extra span and it hides the text by default. It shows the text only after the text box is focused. This doesn't happen though if text is added to the rich text box before the window finished loading. You can easily see this by yourself.

So, on a new project, just add a rad rich text box and in the code-behind add:

public MainWindow()
{
InitializeComponent();
 
var section = new Section();
var paragraph = new Paragraph();
var span = new Span("Span declared in code-behind");
paragraph.Inlines.Add(span);
section.Blocks.Add(paragraph);
radRichTextBox.Document.Sections.Add(section);
}

That will work fine, but if you do this:

public MainWindow()
{
	InitializeComponent();
 
	Loaded += MainWindow_Loaded;
}
 
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
	var section = new Section();
	var paragraph = new Paragraph();
	var span = new Span("Span declared in code-behind");
	paragraph.Inlines.Add(span);
	section.Blocks.Add(paragraph);
	radRichTextBox.Document.Sections.Add(section);
}

you will see that the text box behaves completely different, and it is also prone to throwing different application errors in different circumstances.

Highlight Points on the ChartView Control

This is WPF ChartView Control. I haven't been able to find any way to highlight a specific point on the chartview control. I am using RadCartesianChart, and I like to choose a specific point on the chart to display the white circle (just like the ShowIntersectionPoint on TrackBall movement), but I want to choose a point in code instead. Is this possible?

[Solved] How to get all the text from a rich text box?

Hello,

Is there a way to get all the text from a RichTextBox without having to select all the text first and then call GetSelectedText() on the document selection?

PS: Also, is it possible to get parts of text without having to select it first? For example, if I want to get the text on a line, i currently do this:

// Get line text range.
startPosition.MoveToCurrentLineStart();
endPosition.MoveToCurrentLineEnd();
 
// Clear the previous selection.
richFolderList.Document.Selection.Clear();
// Select line text.
richFolderList.Document.Selection.AddSelectionStart(startPosition);
richFolderList.Document.Selection.AddSelectionEnd(endPosition);
 
var currentLine = richFolderList.Document.Selection.GetSelectedText();

[Solved] drag and drop between grids with collection data

Hello,

is there any way to achieve WPF .NET 4 drag and drop between grids with different data, for example on the left grid (drag source) you have products and on the right grid (drop target) we have Orders, Orders has Name and Date plus collection of Products, Order
grid can be grouped with expand collapse by Products list (we can hide or show all Products within an Order), and finally we can drag Product from left grid to particular Order in the right grid?

Orders grid looks like this (it has expandable childtemplate with Products):

<telerikGrid:RadGridView x:Name="TelerikOrdersGrid" AutoGenerateColumns="False" ShowGroupPanel="False" Grid.Column="0">

<telerikGrid:RadGridView.Columns>

<telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Name}" Width="100" />

</telerikGrid:RadGridView.Columns>

<telerikGrid:RadGridView.ChildTableDefinitions>

<telerikGrid:GridViewTableDefinition />

</telerikGrid:RadGridView.ChildTableDefinitions>

<telerikGrid:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerikGrid:RadGridView x:Name="TelerikProductsGrid" telerikDragDrop:RadDragAndDropManager.AllowDrop="True" AutoGenerateColumns="False" ShowGroupPanel="False" ItemsSource="{Binding Products}">

<telerikGrid:RadGridView.Columns>

<telerikGrid:GridViewDataColumn DataMemberBinding="{Binding ProductName}" Width="100" />

</telerikGrid:RadGridView.Columns>

</telerikGrid:RadGridView>

</DataTemplate>

</telerikGrid:RadGridView.HierarchyChildTemplate>

</telerikGrid:RadGridView>

How exactly I register RadDragAndDropManager.AddDropQueryHandler for TelerikDetailGrid?

When I try in code behind:

RadDragAndDropManager.AddDropQueryHandler(TelerikDetailGrid, RadGridView_OnDropQuery);

I have got error:

Error 1 The name 'TelerikDetailGrid' does not exist in the current context C:\test\MainWindow.xaml.cs 35 55

In other words to add Product to Order by drag and drop? If possible by using multi-select - slecting one or more Product?

thank you
