Senthilkumar · Answer

Hi Selvi, Correct. I have used the script tag. The reason for that you may place the drop down list in panel or some other parent control then sometimes it will be ctl100_panel_ddlParameter. When you say , it will get the generated the client id which displays one in browser.

hi senthil what's this ddlParameter is it dropdownlist id ah

Senthilkumar · Answer

Hi Selvi, Place this function in your script tag. function validate() { var ddlCountry = document.getElementById(' '); if(ddlCountry.value==0) { alert("Not Selected..!"); ddlParameter.focus(); return false; } return true; } If it is selected other than default value then it will not throw error other wise it will show the error. You can see the server side validation also: http://www.ezineasp.net/post/ASP-Net-DropDownList-Validation-using-JavaScript.aspx
