Selecting a value and clicking the button, doing postback, I want to capture the value selected in the ddl. I was using "FindControl method" but it is not working, I guess because the controls are created dynamically and will not show due to stateless HTTP.

I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.
All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.
I got asked to write a java application for my company. I'm a seasoned .Net developer so this is all new ground to me.My task is to produce an invoicing application that has several high level tasks such as:Build single invoiceBuild all invoicesMy company want to be able to call these tasks from a java console application - passing in relevant commands and parameters to invoke the tasks. They also want to be able to invoke the same code from an ASP.NET application.
I am creating user control with two list boxes, in between list boxes two buttons is there to move from one list box to another. Whenever button click i am using javascript to move from one list box to another. i want this user control is working in web from.(java script is not firing means it didn't move from one listbox to another)
The below code works, I'm just curious if there is a dynamic way to pass the generated GridLeft__ctl1_GridViewLeftSearch ID into the javascript function.
If I have a web form with a button control on it. Is their a way to have it's button press method called from a Java Script method? Can someone show me how to do this?I have a hidden button on a web form. I need to simulate it being pressed programatically through Java Script. So I need Java Script to run the code behind method for a button.
protected void PageButton_Click(object sender, EventArgs e) { // How to have this method called from Java Script? }
I know that dynamic buttons and buttons in general don't use a typical postback and they post through the page.request.form. Okay, so in visual studio, I was able to determine that page.Request.form and in the all-keys property, i SEE my button there. It is the last item in all-keys.
When I am clicking this dynamic button which is in an updatepanel, the script below does not detect it as a button, it is still showing it as null:
public static Control GetPostBackControl(Page page) { Control control = null;
[Code]....
but here is the kicker, when I am traversing through the object, I am looking at the object C and the property 'ctl'. The ctl is showing me a value of "ButtonRow_0Col0" and it is of type string. This is good! But , the 'c' control object still says 'null'.

I'm currently writing a web app in ASP.NET MVC 1.0 (although I do have MVC 2.0 installed on my PC, so I'm not exactly restricted to 1.0) -- I've started with the standard MVC project which has your basic "Welcome to ASP.NET MVC" and shows both the [Home] tab and [About] tab in the upper-right corner. Pretty standard, right? I've added 4 new Controller classes, let's call them "Astronomer", "Biologist", "Chemist", and "Physicist". Attached to each new controller class is the [Authorize] attribute. For example, for the BiologistController.cs
[Authorize(Roles = "Biologist,Admin")] public class BiologistController : Controller { public ActionResult Index() { return View(); } }
These [Authorize] tags naturally limit which user can access different controllers depending on Roles, but I want to dynamically build a Menu at the top of my website in the Site.Master Page based on the Roles the user is a part of. So for example, if "JoeUser" was a member of Roles "Astronomer" and "Physicist", the navigation menu would say:
[Home] [Astronomer] [Physicist] [About]
And naturally, it would not list links to "Biologist" or "Chemist" controller Index page. Or if "JohnAdmin" was a member of Role "Admin", links to all 4 controllers would show up in the navigation bar. Ok, you prolly get the idea... Now for the real question... Starting with the answer from this StackOverflow topic about Dynamic Menu building in ASP.NET, I'm trying to understand how I would fully implement this. (I'm a newbie and need a little more guidance, so please bare with me.) The answer proposes Extending the Controller class (call it "ExtController") and then have each new WhateverController inherit from ExtController.
My conclusion is that I would need to use Reflection in this ExtController Constructor to determine which Classes and Methods have [Authorize] attributes attached to them to determine the Roles. Then using a Static Dictionary, store the Roles and Controllers/Methods in key-value pairs. I imagine it something like this:
public class ExtController : Controller { protected static Dictionary<Type,List<string>> ControllerRolesDictionary; protected override void OnActionExecuted(ActionExecutedContext filterContext) { // build list of menu items based on user's permissions, and add it to ViewData IEnumerable<MenuItem> menu = BuildMenu(); ViewData["Menu"] = menu; } private IEnumerable<MenuItem> BuildMenu() { // Code to build a menu SomeRoleProvider rp = new SomeRoleProvider(); foreach (var role in rp.GetRolesForUser(HttpContext.User.Identity.Name)) { } } public ExtController() { // Use this.GetType() to determine if this Controller is already in the Dictionary if (!ControllerRolesDictionary.ContainsKey(this.GetType())) { // If not, use Reflection to add List of Roles to Dictionary // associating with Controller } } }
Is this doable? If so, how do I perform Reflection in the ExtController constructor to discover the [Authorize] attribute and related Roles (if any) ALSO! Feel free to go out-of-scope on this question and suggest an alternate way of solving this "Dynamic Site.Master Menu based on Roles" problem. I'm the first to admit that this may not be the best approach.
is it possible to automatically populate a file upload control's file for automated testing and server stress. I have one upload control (that simply brings up the browse and selects the file) and a button that uploads the selected fileupload control's file. Is it possible to give the file upload control a file pather "C:myImage.jpg" and submit the file by pressing the upload butto:
