You can call that function using Page.ClientScript method
something like:

Page.ClientScript.RegisterStartupScript(this.GetType(), "Test", "YourFunctionName();",true);

Or you can also attach a JavaScript event to a Server Control like:

Button1.Attributes.Add("onclick", "YourFunctionName();");

Or the other easy option would be

Response.write("<script>YourFunctionName(); <\script>")
