Calling C# function through Javascript in ASP.NET
Please support our ASP.NET advertiser: Intel Parallel Studio Home
 |
Not directly, no. Server-side functions live server-side, client-side functions live on the client.
In fact, the only way to get ANY server-side code to run, is to submit the form. ASP.NET unrolls the HTTP headers, unpackages the hidden ViewState variable, re-instantiates objects, and then decides what events to raise based on all of the above.
What you can do is have your JavaScript function set a hidden form variable, then do a form.submit().
Then, in your Page_Load handler on the server, use the Request object to check for the presence and/or value of this variable, and call the appropriate server-side method.
