c# - SSRS report won't launch if multiple parameters in URL -


i trying pass parameters ssrs report .net application.

i have 3 parameters pass: instanceid, el , ol.

in code-behind, have codes below:

        string params = session["instanceid"].tostring() + "&el=unhide&ol=unhide";         string script = "<script language='javascript'> ";         script += "openlink1(" + params + ");";         script += "</script>";         page.registerstartupscript("clientscript", script);

my javascript code below:

function openlink1(params ) {     var str = "http://server/reportserver/pages/reportviewer.aspx?%2f<path>%2f<report name>%2<report name>&rs:command=render&instanceid=" + params;      window.open(str, "list", "scrollbars=yes,resizable=yes,width=800,height=600");     return false; }

no matter do, report won't launch (pop up).

the el , ol parameters supposed hide tables in ssrs report.

e.g. =iif(parameters!el.value = "hide", false, true)

if remove these 2 parameters report , take away parameter in url in code behind, ssrs report launches without problems.

what confuses me if directly enter url in browser, report works fine - lead me believe coding , passing parameters wrong?

any ideas?!

the issue in javascript you're generating in code behind. need put single quotes around params variable when you're creating function call in generated javascript.

    script += "openlink1('" + params + "');";

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
