We were using the Ajax Control Toolkit AutoComplete Extender, but it no longer displays properly with the .NET 3.5 release (May 2009), and it no longer has any cross-browser support. So, we need an alternative that works exactly like the original did. I looked at the info in the thread at:
but the solution does not work like the original extender. In fact it appears that it is not possible to get the ComboBox to work in this manor. The primary purpose of the control is textual input, with the option to select suggestions from the dropdown to populate the text box (just like Bing and Google). I tried to get the combo box to work in this manor, but the control constantly reverts control to the dropdown which makes it impossible to change the text in the text box. Is it possible to get the ComboBox to work exactly like the old Ajax Control Toolkit AutoComplete Extender did?
If not, is there an extender like this for the Input control?
