Mvc - Pass Model From Typed View Back To A Controller Action
Aug 10, 2010I have an MVC application where all the data is tied together by VisitDate table in my database. The home page is a strongly typed view of type VisitDate, all it does is pull up some simple data. Now, here's where I'm having a problem. I need a link that passes the current model in the view back to a separate controller action so I can render a different page with different data. Here are my two controller actions. I'm going from News.aspx to FrontPage.aspx and hopefully passing SchoolVisit. [Code]
View 2 RepliesModel Properties Not Set When Returning To Controller For Post
Sep 3, 2011When I click save on the view, the model being sent to the save method of the controller has no values set, they're all default values. I'm actually using the exact same technique from another project... The data is populated just fine in my view, I can edit it and click save, the code enters the SetSiteTerms method in the controller but has none of the data from the view.
Model:
Imports System.ComponentModel.DataAnnotations
Imports System.Runtime.Serialization
<KnownType(GetType(SiteToA))> _
Public Class SiteToA
<ScaffoldColumn(False)> _
Public Property ID As Integer = 0
[Code] .....
I've updated my view and controller. Why my model is populated, can be editing in the view but when I post with the save button, the model sent to the controller has no data???

Asp.net Mvc - Post IDictionary Back To MVC Model
Dec 18, 2009To make this easier I will use a concrete example using movies and genres. A genre can be associated with many movies. Genres can increase over time and so can movies.
The use case is as follows. The user wants to filter movies by selecting his/her desired genres.
So, I have a page where at the top there is a section where the user can pick any combination of genres to filter on using checkboxes. Below that is a list of movies that are in those genres.
In MVC I am trying to implement this using a ViewPage(of IDictionary(of Genre, Boolean)) where the boolean is whether or not a particular Genre has been selected for filtering.
I then go into loop that creates checkboxes for them to select:
<% for each genre As KeyValuePair(Of Genre, Boolean) in Model %>
<%=Html.Hidden("genre[" & i & "].Key", genre.Key.ID)%>
<%=Html.CheckBox("genre[" & i & "].Value", genre.Value)%>
[Code].....
I am aware this can be done using Ajax and I will most likely do it using Ajax but I would still like to know why this doesn't work.

Get A Row Count And Post That Back To The Grid
Oct 1, 2009Ok, so I have a small program I am building for my boss to keep track of workers at certain job sites. With the way the economy is going my boss wants to track who is showing up at specific sites (jobs) and try to even it out among all the employees - some are not working full time.
Anyway, I have two Access tables linked together with the main table being Employee Data. The second Table is Employee Jobs. Basically I have three forms. The main form on startup will show all of the employees in the company - this is basically a list of all added employees into the database (this is the second form - adding employee info). At a quick glance I would like to have the initial startup form, with grid - show employee info, show the number of jobs each employee has been assigned to. Would this be an SQL statement? How to I get a row count and post that back to the grid so it shows up on startup?

ASP.NET UpdatePanel Lock All TextBox Controls After Post-back?
Nov 2, 2010My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]
Checkboxes Doesn't Post Back - Checkbox On GridView Always Returning False
Jan 22, 2012I have a GridView with a Checkbox on the first column: Code: The thing is that the Checkbox.Checked always returns False. How can I get the checked state of the Checkboxes in this scenario? Or what would be the best approach into updating the aforementioned column? P.S. Note that click on the checkboxes doesn't post back. Nothing happens on the page until the user clicks Save (and that is the intended behavior).

View 2 RepliesPassing Back Lisbox Values When Going Back To Previous Page?
Jul 23, 2009I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

I have a PC logged on to the local network and I want to write a VB.net program that sits on the PC and when the file is created it downloads that file. from the laptop I can type ftp:192.168.43.34 in to windows explorer and see the file without having to type in a username or password (username is set to Anonymous)I require a simple program that just points to the file (ftp:192.168.23.12/banjo.txt) and grabs it to a local path (C:\banjo.txt)I have looked everywhere and not found anything that works and not interested in paying $500 for a library.

Delay In Back To Back Messages Through Socket
May 10, 2012We have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.
Smtp :: Sending Back To Back Emails?
Jun 17, 2011We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.
