populate radcombobox dynamically

[cielo valdoz]

Hi,

Im populating the radcombo box dynamically and getting the data from sql using a webservice. The combo box at the upper part of the page works fine but at the lower part, it generates an error everytime i expand the combo box. I placed the combobox inside the RadExpander.

<Border BorderBrush="White" BorderThickness="3" CornerRadius="5" Grid.Row="1" HorizontalAlignment="Right" VerticalAlignment="Stretch" Grid.ColumnSpan="2" Grid.Column="1" Height="Auto">
                        <StackPanel Margin="0,0,0,0" Height="Auto" VerticalAlignment="Stretch">

Hi cielo,

I cannot see a RadComboBox instance in the provided XAML. Could you please, check if you pasted the rigtht code? In addition, a sample application that could be used to observe the problem would be really helpful.

Hi,

I didn't use RadComboBox, its silverlight control. Anyway I upgraded to Silverlight 4 and Q1 2010 SP1 and it works great.
Thanks
