Hello Shailesh Shahane,
1) This appears to be a bug. The RadComboBox is getting confused is some way, because the first item contains the others, if the succession of items is A, AB, ABC, ABCD it is working fine. We will investigate further and try to fix this.
2) I was unable to reproduce this one. So could you please send us a sample project where the problem can be clearly seen.
Regarding the selection in the combobox TextBox - currently the control
does not provide a way to customize the behavior you describe. We used
the standard WPF ComboBox as a model and tried to make RadComboBox as
close as possible. The problem is related to the fact that RadComboBox
selects all the text in its TextBox when it gets the focus or changes
its selection, and the TextBox automatically scrolls its text. I could
provide the following hack that overcomes the problem:
private void RadComboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
TextBox textBox = RadComboBox1.ChildrenOfType<TextBox>().First();
We will consider adding several properties or methods in the near future, that will help the developers to avoid such hacks.
4) We have tried to make the behavior of RadComboBox similar to the Microsoft Combobox in WPF. You can see that there also the selection changed event is fired on each keystroke. So this is by design.
