Dropdown TextBox (ASP.Net)
If you are a .Net developer, you may notice that there is an important difference (in terms of features) between the WinForm ComboBox and the WebForm DropDownList. ComboBox of WinForm allows user to input custom items if one cannot find the item in the combo list. However, this feature is omitted in DropDownList of WebForm.

In order to make WebForm Dropdownlist as flexible as WinForm ComboBox, I decide to build a custom control using Ajax Control Tool Kit. I call it DropdownTextBox because it combine the features of DropDownList and TextBox. The following is a demo of the difference between traditional DropDownList and my DropdownTextBox:
