You can set the height via CSS: .ui-autocomplete { max-height: 600px; overflow-y: auto; /* prevent horizontal scrollbar */ overflow-x: hidden; /* add padding to account for vertical scrollbar */ z-index:1000 !important; }
Setting IsSynchronizedWithCurrentItem=”True” worked for me!
I tried so many solutions on here that didn’t work for me, only displaying some of the ports. But the following displayed All of them and their information. using (var searcher = new ManagementObjectSearcher(“SELECT * FROM Win32_PnPEntity WHERE Caption like ‘%(COM%'”)) { var portnames = SerialPort.GetPortNames(); var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p[“Caption”].ToString()); var portList = … Read more
It is possible. Use a ListCollectionView with a GroupDescription as the ItemsSource and just provide a GroupStyle to your ComboBox. See sample below: XAML: <Window x:Class=”StackOverflow.MainWindow” xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” xmlns:local=”clr-namespace:StackOverflow” xmlns:uc=”clr-namespace:StackOverflow.UserControls” Title=”MainWindow” Height=”350″ Width=”525″> <StackPanel> <ComboBox x:Name=”comboBox”> <ComboBox.GroupStyle> <GroupStyle> <GroupStyle.HeaderTemplate> <DataTemplate> <TextBlock Text=”{Binding Name}”/> </DataTemplate> </GroupStyle.HeaderTemplate> </GroupStyle> </ComboBox.GroupStyle> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock Text=”{Binding Name}”/> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> … Read more

comboBox1.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDown; comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend; comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
Try this one. cmbEmployeeStatus.SelectedIndex = cmbEmployeeStatus.FindString(employee.employmentstatus);
Well I recently ran into the same problem with null value for ComboBox. I’ve solved it by using two converters: For ItemsSource property: it replaces null values in the collection by any value passed inside converter’s parameter: class EnumerableNullReplaceConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { var collection … Read more
I had the same problem, and found an extremely simple workaround. As everybody else here, I couldn’t find any means to control de behaviour of the component, so I had to accept it. The natural behaviour is: you can’t dynamically populate the list every time the user types into the text box. You have to … Read more
Just change the DropDownStyle to DropDownList.
