How do you know that "javascript doesnt load"? You do know what Response.Write does don't you?

I believe the issue is in your script tag. You need to specify the language as javascript. You also need to put a semicolon at the end of your javascript line. The result should look like this (ignore the double-quotes around javascript - it is a bug in the CP editor that I can't get around):

C#

if (projectID != "0")
{
   Response.Redirect("ProjectDetails.aspx");
}

if (projectID == "0")
{
   Response.Write("<script language='javascript'>alert('Please Select');</script>");
 
}

Looks like above addition of quotes will raise compile error! Though, OP should have got the essence of it.

BTW, I am still unclear on how it is implemented.

yes Sandeep is right the correct code would be:
Response.Write("<script language=javascript>alert('Please Select');</script>");

That is the code I tried to post (only I included single quotes around javascript) but as I posted in my response, the CP editor would not let me put just single quotes - it added the extra double-quotes automatically and I couldn't take them out.

Thats fine. Your point was to direct user and it was done. :thumbsup:

Hi,
Try this:

C#

if (projectID != "0")
       {
           Response.Redirect("ProjectDetails.aspx");
       }

      if (projectID == "0")
       {
           Response.Write("<script language='javascript'>alert('Please Select');</script>");

       }

Are u sure this code would work, i think it will give compile time error in second Resplone.Write() method, here i think we have to remove the quotes in javascript word:-
Response.Write("<script language=javascript>alert('Please Select');</script>");
Or we can use single quote.

I'm not sure I see the difference from what I posted an hour earlier. Did you do something I missed?

Mphirana 17-Jul-12 2:08am

I tried both but messagebox still doesnt show, on bottom of the page writes javascipt:void(0)

_Amy 17-Jul-12 4:42am

Actually i tried writing
Response.Write("<script language='javascript'>alert('Please Select');</script>");
But after writing this in the solution it is coming like above one..
