Hi,

The same problem. AutoSelectOnMatch doesn`t solve it. Has anybody found the solution?

I am experiencing this same issue. In my situation, (a U.S. state drop down list) the post back occurs (to restrict a city dropdown list) immediately after the first keystroke - and the entry textbox area of the dropdown control has only the first character displayed in it. Ideally, the dropdown list should allow the user to type and if a match exists based upon what the user has typed and the user tabs away from the control, that item should simply be selected. However, this does not occur with this control. Is there anything specific I should do to get the dropdown list to behave like a standard dropdown list? (i.e. above desired behavior)

Thanks,

I'm have the exact same problem you described here. Did you find a solution? Appreciate the help.

Hi, I've added AutoSelectOnMatch="false" however SelectionChanged still fires on every time I type. 

when I use AutoPostBackFlags-SelectionChanged="On"
it always select the first on list when I use arrow down to select an item

I use 2011.1
