Hi,

I'm adding additional title bar buttons to the RadPane using the example in your documentation.   In order to get events when the buttons are clicked I am using the routed events mechanism as described in the same section. 

This is working well, when a button is pressed the event is fired in the application.      The hard part solved I guess, what I can't seem to figure out is quite how to identify the RadPane control which the button was fired on?

My RadPanes are all dynamically created along with the RadDocking control.

I was looking for events to be fired when a RadPane becomes selected but I couldn't get this to work either.   Any suggestions would be welcomed.

Kind regards
Neil

Hi,

I have the following problem: I have a GridViewDataColumn with a custom CellTemplate. This works OK for the display of the data. This template is also used in the filter popup for the column, but when I group by this column, then in the group header this template isn't used. Instead the ToString()-representation of the databound object is used.
Why is the custom CellTemplate is not used for the group header or which Template must be customized?

Thanks,

Dany

Hello,

Can RadGridView columns be placed in a ResourceDirectory assigned to the GridViewColumnCollection or does one have to use a control template to accomplish this?

Thanks.

Hello again :)
Imagining that I have a Customer class, and the client has a List <> with the days he was in the store, can I create a line for each client and the columns by the List <>?

Hi,

In my application I have a grid where  all columns are build dynamically in the code behind.
The user can, with the aid of a combobox, select a different layout for the gridview.

When there are many columns in the grid (and the horizontal scrollbar is visible) then I get the following error when I change the
layout:
System.ArgumentOutOfRangeException was unhandled by user code
  Message=Specified argument was out of the range of valid values.

Hello
I have a datagrid with 30 rows and 30 columns, can I make a selection with the mouse of the column 15 to 20 on lines 8 and 10? And do not select the entire row or column all?

Hi,

I'm using the RadDocking control and added a handler for PreviewClose to be notified when a RadPane closed.  This is firing ok, however I'm not quite sure how to get the RadPane control more importantly the Name of the control which is being destroyed,  I need this to clean up my data storage behind the scenes.

Please can some one provide me with an example or point me in the right direction?

Kind regards
Neil

Hello

The list is too long when I set the time interval to 10 or 15 minutes. and set the columns to 3.

Is it possible to have a scrollbar for the dropdown list of timepicker like the datetimepicker in the radscheduler?

Thanks.
