Hi All,<BR><BR>I am trying to capture the selectionchanged event on the drop down box. I have some code written in its event which makes a textbox visible upon a particular selection. The problem is when I select any option in the drop down, the value in the other two combo box gets lost. Basically there are 3 drop down.<BR>My page load event has the autopostback property check for that page.<BR><BR>Can you please let me know how can I capture the selectionchanged event of one drop down and not lose the values in the other two drop down. Another information, all the three drop down get populated in the page load event with a data set.<BR><BR>Thanks a lot for your help!
