You need to do something like ddldocInge.SelectedIndex in your script.

Solution 2

Instead .value use .selectedIndex.

C#

if(document.getElementById("<%=ddldocInge.ClientID%>").selectedIndex == -1)
        {
          alert("Select the Doctor");
          document.getElementById("<%=ddldocInge.ClientID%>").focus();
          return false;
        }

Are you calling the javascript from the button? Share the full code

LebneizTech 2-Sep-11 8:16am

Yes,
All Condition is working except it.
<script language="javascript" type="text/javascript">
function IsValid()
{
//var isNum=/^(\".*\"|[A-Za-z]\w*)$/;^[a-zA-Z0-9]{1,11}$ \d+/2010
var IsID=/^[a-zA-Z0-9]{1,11}$/;
var ID=document.getElementById("<%=txtpatcode.ClientID%>").value;
var mach1=ID.match(IsID);
// var IsRN=\d+/2010;
// var RN=document.getElementById("<%=txtipdregno.ClientID%>").value;
// var matchRN=RN.match(IsRN);
if(mach1==null)
{
alert("Please Enter Valid Code");
document.getElementById("<%=txtpatcode.ClientID%>").focus();
return false;
}
if(document.getElementById("<%=txtfirnam.ClientID%>").value=="")
{
alert("Enter the Name");
document.getElementById("<%=txtfirnam.ClientID%>").focus();
return false;
}
if(document.getElementById("<%=ddldocInge.ClientID%>").SelectedIndex==-1)
{
alert("Enter the DR");
document.getElementById("<%=ddldocInge.ClientID%>").focus();
return false;
}
if(document.getElementById("<%=txtipdregno.ClientID%>").value=="")
{
alert("Can Not be Blank");
document.getElementById("<%=txtipdregno.ClientID%>").focus();
return false;
}
}
</script>

In selectedIndex, s should be small letter and I should be capital letter.
