Hello,
I'm using dotnet 3.5, WPF.
XP pro SP3.
IE6.0.2900
RadControls_for_WPF_2009_1_0526_TRIAL
C#

I have created a simple RadGridView  with a GridViewComboBoxColumn column.
I have added a combobox "DataTemplate" so that the column cells will look like a combo, and not just
when pressing on one of the cells.

In the constructor of the window1, I call FillStatusComboColumn() to fill the combo with possible values.

*** The problem is that using the "DataTemplate" in the XAML causes the values in the
combobox to disappear. ***

Any ideas ?

Thanks

E. S

Hi,

I've made a simple program with a RadCarousel in it.  The thing is, I would like to use my own Buttons (outside the carousel) to scroll through the RadCarousel instead of the carousel's default horizontal/vertical scrollbars.  Is there any way to tell the RadCarousel to scroll one way or the other from inside a Button's MouseLeftButtonDown event handler?  I've been trying to achieve this through RaiseSelectionChangedEvent (but can't seem to access the selected item's index) or ScrollViewer (but can't/don't know how to access the carousel's internal ScrollViewer).  I haven't worked a lot with scrolling in WPF before, so I may be missing something obvious.  Any light you could shed on this problem would be very much appreciated!

Thanks,

UIdev

I am working on my first WPF project and just started using RadControls for WPF so please forgive me if this is a stupid question :)

I have a RadTreeView with CheckBoxes (IsOptionElementsEnabled = "True" , ItemsOptionListType="CheckList")
In my code behind, I can see which items are checked or not using the "CheckedItems" property. Very nice.

However, how can I change the CheckBox status on individual items in my RadTreeView (check/uncheck) from code behind?
What is the best way to check/uncheck all checkboxes from code behind?

Kind regards,
Lars Bodin

 

 

 

I'm using the WPF controls, and cannot find any documentation on RadMaskedTextBox.  The API reference has no comments.  How would one know what mask formats are supported?

Hi,


I have a RadTreeView bound to my datasource and everything is working fine, however, I am having trouble when adding a new object to the underlying databound  collection, your documentation does not seem to cover this scenario in depth. What I would like to achieve is this:-

Each time the user right clicks on a treeviewitem a dynamic context menu is built and displayed. (it has to be a dynamic context menu because each node represents a particular business event)

On selection of a menu item , a new node is added to the tree , brought into focus and in edit mode.

I require a reference to the treeviewitem each time the user selects a node (I am a bit confused why the SelectionChanged event does not pass me back a reference to the treeviewitem)


Thanks

Hi

Is there any reason why the edited event fires twice after editing the radTreeViewItem

Hav i missed any dll's while installing RAD controls ?
I've installed trail version of RAD controls.

Hi,

I currently have 2 issues on the width of a column.

1) if you change the size of the 1st column by dragging the separator and 'hide' the column, you can't get it back. All the other columns can be restored, but the 1st isn't restorable. This only happens when the user can't freeze columns.


2) It seems like the auto-size functionality of the columns only works 1 time. Normally if you resize a column and double-click on the separator, the column will auto-size to the right size. Currently, this doesn't appear to work, with any of the ColumnsWidthMode values.

Hi ,

Few minutes back i've installed RAD controls for WPF.When i tried to acces the quick starts i'm getting error.
Even i couldnt able to access the online version of Quick starts ...its showing error message in browser which something goes like this.
