Hi,

if possible attached your project sample here.
om prakash13y ago
XAML :

DisplayMemberPath="Description"
SelectedValue="{Binding SelectedHourType}"
Grid.Row="6" Grid.Column="1" />

csFile:

HourTypes = new EnumToDropdownMapper().Map().OrderBy(x => x.Description).ToList();
/// string ss = HourTypes.ToList()[0].Description;

i want to bind my enum here only "normal Time" while page loading after that while clicking combo box i want to select other enum values

public enum HourType
{
[EnumDisplayName("Normal Time")]
NormalTime,

[EnumDisplayName("Over Time")]
OverTime,

[EnumDisplayName("Double Time")]
DoubleTime
}

Hi,
If u r using silverlight5 or if u r using mvvm mode in that then u can do this by using binding like as
/>

in this case you have to bind your collection to "ItemsSource" property and make single value of same collection and bind this single to "SelectedItem" property. And keep mode in "TwoWay"

Set that single property in viewmodel to any value of collection.
