Part 6 Calling asp net web service from javascript using ajax

[@bookingsessential]

You are my "go to" guy for all training video's. Great job as usual.

[@saurabhpaul5485]

Dear Venkat. Thanks a ton for the video. Though you have tried to put together service and client in the same project for simplicity of explanation may be but actually I was trying the same by keeping both in different projects but I am getting server method failed error from the failed callback function. Could you please reply on how to go about it so that this part will be clear to us as I can see lot of other viewers are also having the same query. Thanks in advance. Best Regards, Paul

Hey man, if this helps.... you can get the connection string by right clicking on the database and properties. The full connection string of any database would be there. Just copy the text and paste it in web.config file.

[@nathanjayyang2938]

You need to add attribute [System.Web.Script.Services.ScriptService] to your StudentService class . To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

[@the-gray-haired-developer]

Hi Venkat, Lets say your GetStudentById function returns a data table, then how will you make use of data table in java script function like you used with result parameter in java script function which is student object. You accessed the properties on result with this format --> result["name of the property"]. But what if I have a data table in hand. Can it be accessed like --> result.Rows["name_of_column"] ? It's not working tis way. ? Also, I have my web service in different project. How can I add the service reference path in script manager , if my web service is in different project? You can find the question details here : stackoverflow.com/questions/41880547/how-to-make-use-of-data-table-which-is-returned-by-an-asmx-webservice-in-java-sc Thanks, Ankit
