Hi
Currently I display ColorEditor in a RadExpander in a RadPropertyGrid. When the expander is expanded the whole RadPropertyGrid expands to accommodate it.
Is it possible to present the ColorEditor initially collapsed so user can click to expand and spill outside of container as you can with the ColorPicker?
Or is there another container control I can use to emulate this?
Thanks
Craig

Data binding problem with SelectedItem in child grid

Hello,
I have a problem binding the SelectedItem of a child grid to a property on my view model. I've included the relevant XAML at the bottom.

The data binding of the SelectedItem of the parent Group finds the view model property okay. I've tried to use the same approach for SelectedItem of the child grid but a get a binding error 'BindingExpression path error: 'SelectedGroupItem' property not found on 'object' ''Group' '. Group is the type of the child object so I can understand why it complains.

//Groups defined in the view model

public ObservableCollection<Group> Groups { get;set;}

...

//Group class

public class Group

{

public Group()

{

GroupItems = new List<GroupItem>();

}

public string GroupName { get; set; }

public List<GroupItem> GroupItems { get; set; }

}

How do I change the SelectedItem="{Binding SelectedGroupItem}" data binding expression to refer to the view model as the parent grid has done?

Craig

DataAnnotation derived ValidationAttribute

I'm using DataAnnotations for validation. Built-in MS annotation such as [RequiredAttribute] works fine but custom annotation are firing and validating properly. However, the cell aren't getting the red border, only the error message tooltip. Any idea why?

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
public class MustBeUniquePostalCodeAttribute : ValidationAttribute
{

private bool v;

protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
DcfItemViewModel instance = validationContext.ObjectInstance as DcfItemViewModel;

v = true;
if (instance.isNew)
{
string postalCode = instance.PostalCode;
IList<Dcf> dcfList = instance.Parent as IList<Dcf>;
Dcf dcfEntity = instance.dcfEntity;

bool exists = dcfList.Any(d => !d.Equals(dcfEntity) && String.Equals(postalCode, d.PostalCode, StringComparison.OrdinalIgnoreCase));

if (exists)
{
v = false;
return new ValidationResult("Value must be unique");
}
}

return ValidationResult.Success;

}

public override bool IsValid(object value)
{
return v;
}

}

Format Edited Value

Hi,

When I edit cell values the new values don't get formatted.

For example, if I edit a value on a column which has a data format string of N2 and I enter the number 1.2345678 I would expect the number to be formatted to 1.23 but the full number is displayed.

I was wondering if there was a way to get the edited values to adopt the formatting specified on the column?

Thanks,

Steven
