Hey guys, i had a few questions regarding the docking control. I am looking to implement the dock control as a tabbed interface, so the docked windows begin docked and will function as tabs that can be dragged off the tab area into floating windows for viewing multiple at the same time, or docked below the tabs so that multiple tabs can be viewed and compared. There a few behavior things i was wondering about:

1) can you add a button to go to the next/previous tab?

we are hoping to add buttons into the dock windows that allow the user to click a left or right arrow to navigate to the next or previous tab (similar to navigating many web slide shows). how can it determine which window is previous or next in the list and bring it into view?

2) can the dragging a floating tab to the tab area dock it?

right now the only way to dock a floating window is to hover over the dock pane and then drag it to the center of the compass. Is there any way to make the tab area function like the center of the compass, so users could drag to the tab area to dock a floating window?

3) can dragging docking a window to the left or right side split the area below the tab area, respecing the existing tab interface?

right now if you drag a floating window to the compass and drop it on the left it pushes the tab area to the right. we would prefer that it respect the main tab area and dock within the pane below it.

Thank you,
Matt.

DataFilter crashes if item text has underscore

Hi,

Our client has reported an error produced on filter when item has any underscore. We are using Telerik 2012.2.607.40

If user clicks on checkboxes it filters items as expected but if user clicks on text it raises the following exception:

System.ArgumentNullException was unhandled

Message=Value cannot be null.

Parameter name: element

Source=Telerik.Windows.Controls

ParamName=element

StackTrace:

var items = new ObservableCollection<string>();

for (int i = 0; i < 50; i++ )

{

items.Add("Item_" + i);

}

this.RadGridView.ItemsSource = items;

}

Indeterminate image of scrolling dots instead of rotating circle

I have been looking at the WPF Controls example for RadBusyIndicator in the "Demos - RadControls for WPF Q3 2012" application, and I cannot figure out how to have my own application display the left/right scrolling dots instead of the normal rotating yellow circle that I am appearing to get by default. For right now, I can set the BusyContext to whatever text I want and turn the IsBusy on and off in my C# code, and that is all working fine. The IsIndeterminate flag is set to True in my XAML.

From the controls example app, there are only 3 files shown for the configurator example, and I can't see how the busy indicator is being changed. Is there something that I am missing, or is there some C# or XAML not being shown in the controls example app that is modifying the indicator?

RadPane ElementLoaded doesn't reflect changes in AffectedElement

Hi,

I have following code, which should hide unknown elements when deserializing layout xml

private void dockManager_ElementLoaded(object sender, LayoutSerializationEventArgs e)

{

if (e.AffectedElement is RadPane)

{

RadPane paneView = e.AffectedElement as RadPane;

ILayoutPane paneVM = viewModel.LayoutPanes

.OfType<ILayoutPane>()

.FirstOrDefault(vm => vm.Id == e.AffectedElementSerializationTag);

if (paneVM == null)

{

paneView.IsHidden = true;

}

Althought paneView.IsHidden = true is called, the pane is still visible after the LoadLayout.
I tried to set title of the paneView.Title as well. Title was not displayed.

Layout file look like this:

<RadDocking>

<DocumentHost>

<RadSplitContainer>

<Items>

<RadPaneGroup SelectedIndex="0">

<Items>

<RadPane IsHidden="False" IsDockable="True" />

</Items>

</RadPaneGroup>

</Items>

</RadSplitContainer>

</DocumentHost>

</RadDocking>

And another question, or request:
How can I prevent element from being serialized or deserialized? ElementLoading and ElementSaving should have cancelable EventArgs.

private void dockManager_ElementLoading(object sender, LayoutSerializationLoadingEventArgs e)

{

if (e.AffectedElementSerializationTag == null) e.Cancel = true;

}

Thanks

RadViewChart always has 0 on y-axis when the values are negative, even when they are not near 0

Hi
I'm doing a RadCartesianChart with a ScatterLineSeries. When the y-values are negative, the chart always extends the vertical axis all the way from 0, even if the y-values are nowhere near 0. Say, for instance, if the y-values only vary between -10 and -11: The graph displays the area between 0 and -12 so that there is a large empty area above the line and my graph comes out quite flat. Losing a lot of the information that could have been expressed. I attach an example in a jpg.

The behaviour I would like, and that I think would make sense, is that the y-axis extends just around the values in my dataset. This is what happens for positive y-values, I can't see why there is it's different for negative values.

I have tried using RangeExtendDirection="None" and Minimum="{x:Static System:Double.NegativeInfinity}" Maximum="{x:Static System:Double.PositiveInfinity}" on the telerik:LinearAxis elements, neither make any difference.

Is there any way to fix this? I attach a simplified version of my graph xaml below.

Thanks
A.M

<telerik:RadCartesianChart Name="LineChart">
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:LinearAxis />
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis />
</telerik:RadCartesianChart.VerticalAxis>
<telerik:RadCartesianChart.Series>
<telerik:ScatterLineSeries Name="Series" ItemsSource ="{Binding}"/>
</telerik:RadCartesianChart.Series>
</telerik:RadCartesianChart>

Ability to customize chart?

My customer has handed me some new requirements that makes me wonder whether Telerik's ChartView can deliver upon.
For sake of simplicity I attached an illustration and marked the three features that's being requested:

A: Is it possible to add areas like in the illustration. I would need to be able to add one such area per series.
B: The area might have to change its size at some point along the X-axis and it would be great if I could highlight and textually present those points somehow
C: The series would need to be drawn differently outside the marked min/max areas. Is this possible?

I've looked at PointTemplateSelectors for feature C but I don't understand how to move on with that. How would I get to the selected color for example?

Thank you

Merge Reports

The RichTextBox has got a great merge-function.
We are very pleased with this feature.

Now and then we need a sort of master-detail possibility in our merge-letters.

Think about a mailmerge-letter to your customers.
We could use the mergefields for name, address and so on.
But you would like to use a mergefield to view a list of orders which is different for every customer. Master-detail!

Have you thought about something like that?

And how about combining the mailmerge in the RichTextBox with Telerik Reporting?
