[jck6288]

i am developing winform application.there are three textbox named patient last name ,first name,DOB and on lost focus event of DOB I had a requirement to show pop up like menu .That pop up will show patient last name ,first name,DOB from patient table matching records from database based on values entered in firstname,last name,DOB textbox.
I need to show that pop up 4 times based on following search criteria.

2> second pop up will display records based on last name matched
3> third pop up will display records based on first name match
4> fourth pop up will display records based on DOB matched.

You could use a ComboBox control for that what you want.

but how to use searching in combobox..
Could you elaborate exactly whats in your mind..I already tried with combobox..

ComboBox has FindString and FindStringExact methods.
Look here for an example of use.

Have you tried using 2 comboBoxes?

One can be for the search(i'll call it 'Search') criteria so load it with these options: 'All', 'First Name', 'Second name', 'DBO'.

On the DBO_LostFocus event you can check the 'Search' combobox'es selected index, perform the relevant search and load the 'DBO' comcobox with the results of the search.

It should work.
