Question

I have an ASP.NET page, where the user is able to trigger a console app on our server, which generates a file. What I want is the user to see a message that states ‘Requesting file’, then as soon as the file becomes available (i.e. File.Exists for the file returns true), the Requesting file message will change to a link of the file.

Is this easy to accomplish in ASP.NET?

Answer 1

In you web page implement a JSON call to a certain WebMethod which checks if the file has be been generated or not.

you can add your message in the calling function and clear it in the complete event, where you can create the link to the file also

function ddlLeaveChanged(sender, e) {


if (leaveTypeId != '-1' && dateFrom != '' && leaveStatusId != '-1') {
     $('#lblMessage').show();
    $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        url: WebServiceUrl + 'YourMethod',

        success: FunctionSuccedded,
        error: FunctionFailed
    });
}

function FunctionsSuccedded(result, e) {
if (result) { $('#lblMessage').hide(); }

}
