You must trim the string if (trim(document.getElementById("<%=txtHeading.ClientID%>").value)=="") { alert("Enter News Heading"); } function trim(stringToTrim) { return stringToTrim.replace(/^\s+|\s+$/g,""); }

EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

Use a RequiredFieldValidator. It don't allow spaces.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia How to use google | Ask smart questions
