is there a way to force the grid to only select a single row even in child tables

what seems to be happening (2010 Q1) is that i can select a row in the parent table and also select a row in the child even though i have selectionmode set to single

Hi,

when using the beta-dlls with a custom theme (http://www.telerik.com/community/forums/wpf/scheduler/custom-theme-how-to-get-categories-working.aspx) the Visual Studio XAML-Designer stops working with the following error:

Hey,

I was testing the column filtering functionality (where the filter box is inside the column header) and it is crashing the application in the Beta Q1 assemblies.

 

When the filter string is typed into the column filter box, and 'enter' is pressed, the application crashes.

I havent tested for this particular error within my own app, only in the wpf demo.

Thanks,

Is there any way to make the WPF RadGridView navigate down and up when pressing enter/shift enter like Excel does while remaining in edit mode. Currently when you fill in data in a column you have to press enter to exit edit mode, press down arrow and the press F2 to enter edit mode again. Not very effective when you are filling in 150 rows.

While on this topic, it would be great to have the rest of the Excel navigation in here like automatically entering edit mode when you start typing and being able to use the arrow keys for navigation when in edit mode.

I've referred to the demo to persist user grid settings (sort orders, grouping, columns, etc.) and it works great!  Problem is...it only works when I load and unload the control where my grid is hosted.  How can I persist these grid settings when my application is closed (a user clicks the red X in the upper-right to close it down)?  Do you have an example of how to accomplish that...as I'm guessing I need some code in the Application.xaml file or its code-behind.

Thanks!

To clarify items in the list of a combobox I need to alternate background color, like in a gridiew or similar.

Hi,

I would first of all like to say 2010 Q1 looks great!! Nice work.

Secondly, I am developing with the RadRibbonBar, I know there were a few issues when using it when minimised, such as the Ribbon not minimising itself again when lost focus. This is now fixed, which is great, however the Ribbon does not minimise when button has been clicked.

I have a Ribbon bar with buttons which when clicked display open a tab just below the ribbon, the tab opens fine but the Ribbon does not minimise. Is this by design?

Also, the first tab is always selected on load, I have all my RadRibbonTabs.IsSelected = False,  once a Tab has been clicked and minimised, no tabs are selected. I have also tried looping through the RadRibbonBar.Items collection and setting RadRibbonBar.SelectedTab=null but there is tab always selected.

One other issue I came across was when I dragged my application and placed it across my two screen and clicked on a Tab, the ribbon tab opened off screen to the left or the right, instead of directly under the tab header where it should open.

One other question, has integration of the RibbonBar into the main application window been implemented in thithe 2010 Q1 release?

Thanks again!
