Its my program. In this I want custom filtering on "Age" column so that when I give 44 in text field of "Filter" then it should display 44 for "Age" column only. How can I customize my filtering?? Also how can I get the result for Query through that "select * from table where Name='Boy and Age=20 ang Price=44.84'" ??

Answer 1

Why is it that you can figure out how to use the "Bold" button, but you can't figure out how to use the "Code" button. Try using the "Preview" button to figure out which button is more usefull when posting code. I for one can't be bothered to read unformatted code.I don't think the OP masters the "bold" button either. The markup for bold formatting is the star '*', I guess we just witness his/her javadoc comments being misinterpreted as bold formatting :o)
