And how exactly is it "not working"? Have you debugged it with Fiddler or IE9 Developer Toolbar to see what data is sent? Are you sure, that multiple data type is good for you?

Thanks Zoltan for quick reply,
yes i checked data is sent properly, but still the same issue its not calling the server side method

Try a simpel test first (
Be aware of ScriptService attribute!

Check the datatype. Also what is the parameter that you server side method accepts?

Solution 1


you have a problem with datatype, you have written "text JSON" there are not such data type of json

dataType: "text"

dataType: "JSON"

you can find more about datatype at jQuery Ajax[^]

But here is. Read the link you have given:
"multiple, space-separated values: As of jQuery 1.5, jQuery can convert a dataType from..." and so on

Try passing parameters like below,

data: '{"status":"'+$("#status").val()+'", "forDate":"'+$("#SelectedDate").val()+'"}',


data: JSON.stringify({ status: $("#status").val(), forDate: $("#SelectedDate").val() }),

I remember that the first one worked for me when I had a similar issue, Hope it helps.
