textbox event not triggering until tabbing off

Hi,
On my form I have a txtbox say txtbox1 as part of a number of
fields, mainly combo boxes that are involved in a search. However I have a
imagebutton called
imgCmdSearchListings with the following event
OnClick="imgCmdSearchListings_Click".

However when a user changes text in a text box but does'nt tab off the field
clicking on the imagebutton does not trigger the OnClick event. They have to
tab off the field in order to trigger this event. Do you know a way of making
the click event occur without them tabbing off the field.
