I have a node with one connector (custom named). When I create a connection from this connector, a number of things can happen:

1) If I quickly create a connection, RemoveItem() is called and the connection disappears. The event is not triggered!
2) If I slowly create a connection, the e.ManipulationStatus has value ManipulationStatus.Moved.

First of all, I would expect the same behavior no matter how fast I click and release the mouse button. Please fix this!
Secondly, if I click on a connector and start dragging a new connection, I would expect ManipulationStatus.Attaching. The target will be null, but a connection was still attached to the source, wasn't it?

Two important bugs in my opinion.

Double click inside the cell not selecting the word before or after underscore('_')

Hi,

I have one RadGridView, inside that i've one GridViewDataColumn where user can enter the details.
I am facing issues when the entered value is having underscore(_), say Motor_1, so when user double click after 1, instead of selecting the full word only 1 get selected.
What can i do in order to select the full word on double click irrespective of any special characters.

Thanks,

Future Support For WPF 4.0

Hello,

I was just wondering what your future plans are for supporting WPF 4.0?

I have several clients and projects that are built specifically for Windows XP systems and my clients have no 'business' reasons to upgrade their systems to a newer operating system.

This puts me in a bit of a situation. I have not upgraded my developer environment to Windows 8 or Visual Studio 2012 because Microsoft is not releasing updates for Windows XP or the .Net Framework 4.0. So, basically I need to remain 'compatible' with my clients build so I can continue to support them.

However, I'm a little nervous that support will get pulled for WPF 4 (Telerik Controls) and the .Net Framework.

Can you please share some thoughts with us? What's the support 'road map' looking like for WPF 4.0?

Please let me know and thanks!

~ Dave

Change ColumnBackground at Runtime

I am able to set the ColumnBackground at design time in the XAML, but when I try to set the ColumnBackground at runtime when my Window is loaded, nothing happens. For example:

myGrid.ColumnBackground = new SolidColorBrush(Colors.AliceBlue);

Is it possible to set the ColumnBackground at runtime?

Problem with resizing GridView

Hello. When I am resizing my GridView some cells can be displayed without borders (like merged) (in Expression dark theme, other themes work fine). Is it bug?

UPDATE: In other themes I found the same problem. I was doing very fast horisontal resizing

<Style x:Key="GridViewStandardStyle" TargetType="{x:Type controls:OlbGridView}">

<Setter Property="IsReadOnly" Value="True"/>

<Setter Property="GroupRenderMode" Value="Flat"/>

</Style>

RadCartesianChart Performance goes down when clicking combobox

I'm developing an application which uses the RadCartesianChart. There is also a ComboBox where I can choose some values. The performance of the Chart control is well (zooms and pans normally) until I click on the ComboBox. After this, the performance of the chart lacks. Panning and zooming is very slow. There are 288 values in this chart.
The problem appears on my computer (Core 2 Duo T9600). The problem doesn't appear on another computer (i7). I'm confused, because the ComboBox is needed. Telerik wpf controls are in v2012.2.607.40

Here the XAML:

Bring children into view on expand node

Hi,
I'm trying to replicate the way Windows Explorer works when you expand a node.
If you expand a node with child items, and those childred expand beyond the view, the view scrolls so that as many of the child nodes as possible are displayed.

Currently I have this code, which works the first time a node is expanded, but stops to work after contracting and expanding.

private void Tree_OnExpanded(object sender, RadRoutedEventArgs e)

{

var originalSource = e.OriginalSource

as RadTreeViewItem;

new Thread(() =>

{

while (originalSource.ItemContainerGenerator.ContainerFromIndex(0) == null)

Thread.Sleep(100);

Dispatcher.BeginInvoke(new Action(() =>

{

tree.BringIntoViewMode = BringIntoViewMode.HeaderAndItems;

originalSource.BringIntoView();

tree.BringIntoViewMode = BringIntoViewMode.Header;

}));

}).Start();

Is there a better way to implement this behavior?
