We have noticed that if you bind this contol to a list of say 8 items it opens properly
rebind it (we have this control on a screen that is constantly changing Items source to a selected value)
to say 1 item. It opens correctly
rebind it back to the list with 8 items it drops down open only showing one item
Hello,
I am just checking if you require any further assistance on the matter.
Thank you for your feedback. I will be waiting for the application which presents your issue.
I have been investigating your issue by setting the ‘ItemSource’ in XAML and it seems that everything goes right. In the provided code I see that you have handled the ‘DropDownOpening’ event. Maybe something in your code-behind makes this unordinary behavior. When it is possible, please, modify my sample application reproducing the same behavior like in your application or attach your own one for further investigating.
Looking forward to hearing from you.
tried it no difference (you are also using code behind we are databinding)
here is our xaml (flagCriteria is the list that changes size depending on which onbject is the SelectedIndicator)
<ig:XamMultiColumnComboEditor x:Name="cboFlagRules" DropDownOpening="cboFlagRules_DropDownOpening" AllowDropDownResizing="True" AllowMultipleSelection="False" SelectedItemsResetButtonVisibility="Collapsed" FilterMode="FilterOnPrimaryColumnOnly" DisplayMemberPath="CriteriaName" SelectedItem="{Binding Path=SelectedRule,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" ItemsSource="{Binding SelectedIndicator.FlagCriteria,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Center" HorizontalAlignment="Stretch" AutoGenerateColumns="False" Grid.Column="2" Grid.Row="0" Grid.ColumnSpan="2" Margin="5,0,5,0" Cursor="{Binding Path=AppIsWorking,Mode=TwoWay, Converter={StaticResource BusyMouseConverter}}" > <ig:XamMultiColumnComboEditor.Columns> <ig:CheckboxComboColumn Key="Active" Width="50" HeaderText="Active"/> <ig:TextComboColumn Key="CriteriaName" Width="*" HeaderText="Rule"/> </ig:XamMultiColumnComboEditor.Columns> </ig:XamMultiColumnComboEditor>
