find substring in combobox in vb.net
How can i find substring in combobox in vb.net without adding any textbox e.g
List of item in combobox
1. Ice cream vanilla
2. Ice cream strawberry
3. Toffee
4. Biscuits
now if i enter "Cre" in the combobox the combobox shows only first two items i.e
Ice cream vanilla
Ice cream strawberry
or
if i enter "Van" in the comboxbox it will show only
Ice cream vanilla
