I'm trying to come up with a good way to have a cell that can be clicked on to navigate to another window related to the entity chosen in the cell. Typical application navigation. The edit mode for the cell has a button on the far right which opens a pop up window that lets the user query for an instance and choose it. Thus the user is able to edit the relationships of the data. Nifty.

Problem is I'm trying to come up with a good way to both allow the navigation in the cell, and switch to edit view. If I put a button in the CellTemplate, then the button is clicked on, instead of entering into edit mode. And there appears to be no further way to enter edit mode.

I was hoping the grid view had some way to show a control to enter edit mode, that was built in, so I wouldn't have to write it. If not, is there a RoutedCommand that can be raised from within the cell's template in order to enter edit mode? If so, I guess I could put in my own edit button.

I trying to set GridViewComboBoxColumn itemsSource when GotFocus event is fired but it doesn't work.
I ' m using Q2 2010 SP1 libraries and I put

this.AddHandler(RadComboBox.GotFocusEvent, new RoutedEventHandler(comboGotFocus));

in the control constructor while the handler is

void comboGotFocus(object sender, RoutedEventArgs args)

GridViewCell cell = args.OriginalSource as GridViewCell;

if (cell != null && cell.Column.UniqueName == "RegionId")

{

District district = cell.DataContext as District;

if (district != null && cell.Content is LookupElement)

{

string countryId = district.CountryId;

RadGridView gridView = (RadGridView)this.districtRegistryControl.ChildrenOfType<RadGridView>().First();

RadComboBox comboBox = (cell.Content as LookupElement).ComboBox;

if (comboBox != null)

{

comboBox.ItemsSource = null;

if (string.IsNullOrEmpty(countryId) == false)

comboBox.ItemsSource = from r in iGasContext.Context.Regions

where r.CountryId == countryId

select r;

else

comboBox.ItemsSource = iGasContext.Context.Regions;

}

Binding data of a column to an array element

If I use the following binding expression in a GridViewDataColumn

DataMemberBinding="{Binding Path=Days[1]}"

("Days" is an Array like Days[10])

I get the following error in the Visual Studio debug output window:

A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll

and the filter menu button in the column header is missing and the sorting function doesn't work anymore.

If I wrap the array element in a porperty in the business object and use this for binding, everything is fine. What's going on here?

Thanks
