Questions on UI for WPF Forum

Hi.
I found an issue the RadTabControl for WPF. I placed a prism region on the RadTabControl, and I did not use the region adapter the telerik offers online since I need a regular region and not an all-active region.
So the region adapter in use was prism's SelectorItemsSourceSyncBehavior.
New tabs opened as expected, but for navigation to tabs - when I resolved an already resolved view into the region, the view's tab didn't get selected.

I debugged the adapter and found out that it wasn't getting any SelectionChanged events from the control, so I tested it in a new demo app.
I added an event handler to RadTabControl.SelectionChanged and all the events did fire as expected. BUT - when I casted the control into a selector and added an event handler to ((Selector)radTab).SelectionChanged - no events fired.
Since the control actually inherits from Selector, I consider this a bug.

Eventually I just copied prism's adapter code and changed the Selector parts into RadTabControl - and it works. But I don't consider this a good solution for the long run.

Thanks, Moti.

Keep AppointmentDialog open on error

Hi,

I'm using the appointment dialog for creating and editing appointments. I want to inform the user about errors in the dialog. For example if he did not fill out the subject text box. I could catch the AppointmentSaving event, but at this time the dialog has already been closed. I want to inform the user before the dialog has been closed so he can make changes in the dialog. How can I achieve this?

thanks in advance,

michael

unable to get SeriesSelectionMode for ChartSelectionBehavior

i have been using free trial version of telerik tool. I am not getting the property SeriesSelectionMode for a ChartSelectionBehavior
in radcartesianchart.
i am also trying to get the selected points from selected lineseries. these lineseries are selected when a rectangle is dragged over the graph. (for eg. this similar to selecting some lines from notepad and working on those lines.)
the series falling under this rectangle should give the respective data points.
Can u give me some example to work on it. Looking forward for the reply.

Custom TimeMarkers - no text appears

Hi,

I’m binding CategotiesSource to my Categories collection and TimeMarkersSource to my TimeMarkers collection.

While categories are displaying perfectly right in the Edit Dialog, TimeMarkers drop down displays only Brushes’ colors I have defined; no text appears next to them.

What can be wrong?

thank you

Compile to Release errors

Hi

I'm not sure if this is the proper category for my question but I wasn't sure which to use.

I tried to compile for Release after previously successfully compiling in Debug. I get many "Could not locate the assembly" errors. Any ideas on how this may happen would be appreciated.

I am using Windows 8.1, and Visual Studio 2012 Desktop Express.

Thanks

RadTreeListView sorting with ICompare?

Hello,

Is it possible to set a custom sorting for a column, using an implementation of ICompare?

I've got a list like
1.1
1.5
1.10

With default sorting it sorts as
1.1
1.10
1.5

Please let me know :-) Thanks in advance!

Best regards,
Ben

RadMenuItem FlowDirection Changes Header Text

My project uses a RadMenu in the upper-right of the screen. The menu needs to open from right to left so we use the flow direction "RightToLeft". When using this flow direction, some header text with punctuation is rearranged. Consider this example:

<telerik:RadMenu x:Name="radMenu2" ClickToOpen="False" Grid.Column="0" FlowDirection="RightToLeft">

<telerik:RadMenuItem Name="testMenuItem" Header="Test">

<telerik:RadMenuItem Header="123.ABC"/>

<telerik:RadMenuItem Header="123ABC"/>

</telerik:RadMenuItem>

</telerik:RadMenu>

In this case, when the menu is shown the first menu item will display "ABC.123" instead of "123.ABC". The second item (without the period) displays fine.

Other examples:

"Test_" will display as "_Test"
"(Test" will display as "Test("
"100%Effort" will display as "Effort%100"

For some reason, setting a flow direction of "RightToLeft" will rearrange any text that contains certain special characters.

Is there a way to stop this reversal of the menuitem header text?

Dynamic binding series problem.

Hi,

I have a question about dynamic series binding.

This is code example:

public class MyViewModel

{

public List<ChartData> chartItem {get;set;};

public List<List<ChartData>> ChartData {get;set;};

}

public class ChartData

{

public DateTime Xvalue{get;set;}

public DateTime Yvalue{get;set;}

}

ChartData has some chartItem, and one ChartItem will be graph a line in the ChartView.
ChartItem's quantity is dynamic in the ChartData.

What ways can be binding this data in the ChartView? (Lineseries are dynamic.)

Thank you.
