Use JavaScript. On ClientClick of Submit button check DropDownList Text. If it "Blank" or "Select" the throw message and return false.

U need to write the validation in java script for this to work. as follows function ddlValidation() { if (document.getElementById(.Selectedindex) == "-1" { alert('Select the item and proceed'); return false; } else return true; } if u want to show this message on click event of any button say 'Save' for example and id for the button is btnSave then call the above function from coding as follows btnSave.Attributes.Add("OnClick","javascript: return ddlValidation()"); try with this one....

Ya, You can use JavaScript to validate the drop-down list. But side by side, you also should check it in the code-behind on the clieck event of the submit button. Though it will be a server side action, but if javascript will be disabled in the client's browser thn the server side code will do the trick for you. :)

Either you love IT or leave IT...
