Have a touch screen app with a RadCarouselpanels populating a listbox.
(there are 3 usercontrols) . I only need to lock the scrolling on one of the usercontols.
So the user are able to use the touch features.

any thoughts?

Hi,
I'm starting to use your RadCarousel control and I have got a problem.

I want to replace the horizontal buttons with a customized button with a picture.

How could I do this?

Thank you for your help.

Hi,
    I have the following recurrence pattern string DTSTART:20120502T113000ZDTEND:20120502T123000ZRRULE:FREQ=MONTHLY;INTERVAL=16;BYMONTHDAY=2
I use this code to apply it to an appointment
When checking for occurennces it seems to occur every 12 months on day 2 and not every 16 months. In fact any month number over 12 seems always fall back to 12.

Is this a bug or have I got my logic wrong?
Thanks

I have a grid view that has about 450 items in it, with 8 columns on each item. There are 10 top-level nodes.

Expanding or collapsing at any level takes quite a while - click on the arrow, wait almost a second, then the change shows up in the grid. The speed doesn't seem to change depending on whether the tree is fully expanded or fully closed. The treelist is bound directly to a collection.

I did a quick profile, and it looks like it's spending most of it's time in:

Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureChild(class System.Windows.UIElement,valuetype System.Windows.Size,int32)

Any thoughts...

Hello,

I use standard WPF DataGrid for building of dynamically columns  in my 'dgFields'. I want to use telerik GridView.
If greatly simplify my code (for standard DataGrid) then I need similar for RadGridView:

dgFields.Columns.Add(new DataGridTextColumn { Binding = new Binding("Name"), Header = "Column name", IsReadOnly = true });

dgFields.Columns.Add(new DataGridTextColumn { Binding = new Binding("Header"), Header = "Header", IsReadOnly = true });

dgFields.Columns.Add(new DataGridCheckBoxColumn { Binding = new Binding("IsVisible"), Header = "Is Visible", IsReadOnly = false });

dgFields.Columns.Add(new DataGridTextColumn { Binding = new Binding("Description"), Header = "Description", IsReadOnly = true, MinWidth = 258 });

 

foreach (var column in myObject.HyperlinkColumns)

{

    var style = new Style(typeof(TextBlock));

    style.Setters.Add(new EventSetter(Hyperlink.ClickEvent, (RoutedEventHandler)EventSetter_OnHyperlinkClickEventHandler));

    dgFields.Columns.Add(new DataGridHyperlinkColumn { Binding = new Binding(column.Name), Header = column.Header, ElementStyle = style });

}

I need Text, Hyperlink and CheckBox columns with binding.

Thanks,
Dmitry

Hello everyone,

I am currently programming an automation tool using the new native Microsoft UI
Automation API 3.0 (using VC++ 2010, native C++, Win7). The Application
Under Test (AUT) is a WPF application containing some Telerik controls
(particularly RadDocking, RadSplitContainer, RadGroup, RadPane).

UIA works fine - I can install event handlers, navigate through the tree,
search elements using various conditions and control the found elements
using their patterns.

However recently I encountered a behaviour that leaves me baffled: The UIA tree of
my AUT simply is not up-to-date after switching the central RadPane's
content.

After switching the RadPane's content, I can *see* the new controls in the
AUT's GUI but the UIA tree still reflects the controls that have been there
before. The (outdated) UIA sub-tree can be still completely read using UIA
search functions or using a UIA walker but of course it can not be written
since the underlying controls do not exist anymore.

I was not able to force an update of the the UIA sub-tree; neither by
calling any UIA functions nor by restarting the tester application or by
switching the RadPane's content back and forth.

The issue happens only if my tester application does access the
RadPane's UIA sub-tree before it is switched. I.e. the system seems to
memorize the RadPane's UIA sub-tree and keeps the old elements even after
switching the RadPane's content.

This exactly looks like there would be an outdated cache... however I do NOT
use any caching UIA functions at all. None. Never. Nowhere.

Currently I found only one mysterious, cumbersome way to update the RadPane's
UIA sub-tree reliably: Using one of the Microsoft tools "Inspect" or
"UISpy"! E.g. when using the Inspect tool having a brief look into RadPane's
UIA sub-tree (by click-expanding the corresponding node in the tree), the
problem is suddenly gone and my tester application can access the actual,
RadPane's up-to-date UIA sub-tree immediately! Of course this is a temporary
solution only.

I have no idea what Inspect/UISpy is doing to update the UIA tree of an
unrelated application.
Inspect.exe uses the same native interface as I do but UISpy.exe uses the
.NET interface AFAIK so this seems not to depend from the used Microsoft
API. BTW, the tool "Snoop" does not have this effect.

I really need help. Currently I am unable to locate the origin of the
problem. On the one hand this problem happens with Rad controls (and their
content) only, on the other hand the Microsoft tools seem to do the trick
somehow. So I suppose there is some detail I have to know when automating
Rad controls via UIA.

Does anyone have an idea how to approach the problem?

Thanks in advance,
Bernhard

If I add a Column Header or Footer to a GridViewColumn an InvaidOperationException is thrown with a message of "Specified element is already the logical child of another element. Disconnect it first." when I attempt to change the Theme. If I comment out the footer, there is no exception and the theme changes as expected.

Below is the xaml for the RadGridView and following that is the exception details.


System.InvalidOperationException was unhandled

Hello,

I am using your (Telerik) Bar_Rating_WPF custom control for bar graph style ratings. Everything displays well and the click action selects the proper rating bar. Where I am having difficulty is setting or getting a value. I don't see how I can set a datacontext?

FWIW I add the control at runtime:

I'm not going to put the whole source code for the Bar_Rating_WPF user control here as 1. it came from you (Telerik) and 2. it's quite lengthy.

Thank You
JB

Hello!

We have issue with RadWindow used as dialog. This problem is observed on Windowx XP only (we checked on two different computers). It's not observed in Windows 7 (we also checked on two different computers). The issue looks like this: 

• Show modal dialog with title.
• Press ALT+Tab
• See empty text in Alt Tab manager (see screen shot)

Hi,

We are having a slight issue trying to find a solution for the following issue:

We have a Horizontal Bar Chart, using the RadChart in WPF, and have set the screen up so that the chart proportionally resizes with the resizing of the screen.  The issue that we have is that although we can manually set the ScrollMode, RangeStart and RangeEnd so that the axis labels and the chart values are clearly visible and do not overlap, when the user resizes the screen (and subsequently the chart) the axis labels start to overlap and we loose some of the bar values.

Ideally we are looking for a solution that would allow the chart to dynamically set the ScrollMode, RangeStart and RangeEnd values so that the bars on the chart are always shown at the optimal height to remain clear (or to abide to a minimum height).

Any help on this would be greatly appreciated.

Thanks in advanced
