Why is a null parameter being passed to the following controller action?
public FileContentResult GetImageForArticle(ArticleSummary article)
{
if (article == null || !article.ContainsValidThumbNail()) return null;
return File(article.ThumbNail, article.ThumbNaiType);
}
from the following partial view:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<AkwiMemorial.Models.ArticleSummary>>" %>
<%if (Model.Count() > 0) [code]...
I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel
{
//Members:
public Gallery _photo { get; set; }
public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
Here is my master page:
<%@ Master Language="C#" MasterPageFile="~/views/Shared/GeneralMaster.master" Inherits="System.Web.Mvc.ViewMasterPage" %> [code]....
I have added aiax ModalPopupExtender on a web page
<ajaxToolkit:ModalPopupExtender
ID="ModalPopupExtender1"runat="server"[code]....
to fetch data to popup control dynamically I used webservice [WebMethod]public string getIssueDetails(string contextKey){ } But before that I set ModalPopupExtender1.DynamicContextKey = "1_1_60"; in code behind.But problem is in webmethod "contextKey" is getting passed as null.
I am using TextBox1.Tag + TextBox1.Text for a calculator but the Tag part is not accepted. What namespace must I use for it to be accepted in an ASP.NET 3.5 application?

View 1 Repliesrecently i used literals inside HTML elements like so:
Code:
<div <asp:Literal ID="ltlpbEmpty" runat="server"></asp:Literal> align="left" <asp:Literal ID="ltlToolTip" runat="server"></asp:Literal>>
<div <asp:Literal ID="ltlPBFull" runat="server"></asp:Literal> <asp:Literal ID="ltlBarWidth" runat="server"></asp:Literal> align="left">
</div>
in this case both of this divs are part user control progress bar i'm making, from not related reason i couldn't use ASP.NET elements and had to go back to the traditional HTML elements.so to be able to give those elements dynamic attributes such as tooltip, id, class i had to add literals inside those elemtns..

I am a newbie and have designed a website using ASP .Net 2.0 with C# 2005. On the home page I am displaying rates of a few items which gets updated every 15 minutes. The new rates are entered through a different web page into a SQL Table and I am using Page Refresh of the home page to update the rates every 15 minutes. Everything is working ok upto this. But now I have to display a countdown timer of time remaining for the next update on the home page. I am totally clueless as how to approach the problem.
View 4 RepliesI m developing online examination website.
I want to show remaining time during examination without java script code.
I tried that by adding 10 minuts in starting time of examination and then continuously subtracting current time from that added time.
I m using label to show time . But it gives conversion error.
I have a simple web form that takes data inputted by a user online but I can't get the date field formatted so it can allow UK short date format to be entered. I need to allow dates to be entered like this: dd/mm/yyyy but currently if I enter the UK format date 25/02/2011 I get an error, as the field is in US format (mm/dd/yyyy).
It's a SQL database created from within MS Visual Web Developer 2010, and I'm a SQL newbie.
How do I change the date format to UK so UK format dates can be accepted?

View 1 RepliesI have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example
Todays date (02/25/2010)
50 postings
yesterdays date (02/24/2010)
if 75 postings are there,
50 postings
it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this
yesterdays date (02/24/2010)
remaining 25 postings
(02/23/2010)
75 postings
how can i do the paging like this?
Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.

View 2 RepliesI have a page with a Search button, a gridview and a listview. When the Search button is clicked, the gridview fills up with a resultset and has a 'detail' linkbutton on each row. When the user clicks on the detail link, the listview below the gridview fills up with details related to the selected gridview row. My customers have asked if when they click on the gridview row, it becomes highlighted, and remains highlighted while they are working on the detail in the listview. So, I need to highlight the row when clicked, remove the highlight when a new row is clicked (as well as highlight the new row), and remove highlighting when the Search button is clicked. The highlight needs to remain over postback since there could be a full-page postback.
I'm thinking JQuery is the way to go but I am a JQuery novice and so would need a code sample.
I am creating an HTML report (it's to be a form for filling in). I have a table at the bottom of the form which contains a list of items and yes/no checkboxes at the side. I need to have this work so that cells on the left that contain a question have any empty space filled with dots, e.g.:
Short question......................... yes no
Longer question etc, etc............... yes no
Does anyone know of a way of doing this, ideally by CSS, but on the server side if necessary.
I would like to pop up a box that warns the user of session timing out in 5 minutes. There are lots of examples of this on the net and I can figure something out. My question however is how to get the time remaining.All examples I read about set a client side timer to countdown from last postback. I would like to do something different. I would like to make an AJAX call to the server and get the time remaining from the server. Is this possible?Since an AJAX call will not reset the session timeout timer can I read the number and send it back to the client?

Spent ages trying to get this right but am struggling now. I have a list box and textbox, I can happily enter Email addresses into the textbox which are saved into a text file and populated in a list box. I want to be able to select a list item and delete it, along with it's record in my text file. I was going to do it by on the delete list item / button click, it delete's the text file and then writes and a new one with the remaining list items in the list box. Unfortunately it's re-writing the file but either not including the remaining list items. Here's some examples of what I've changed and what populates the text file:
StreamWriter1.WriteLine(Addresses.Items); - System.Web.UI.WebControls.ListItemCollection
StreamWriter1.WriteLine(Addresses.Text); - A blank line?!?
The code is below. The reason I wouldn't allow the user to delete the first list item is because I thought the code was working ok but for some reason putting in a blank line to start with, and if I deleted the line it'd delete all file content. No, I don't know why I thought that either.

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
My gridview has hyperlink field which will redirect to another page when clicked. Is there any way to hide the values from being shown in the URL? I do not wish to have encrypted values as well.
http://localhost:3042/Customer/CustomerDetails.aspx?custid=123456
Any way to show it as
http://localhost:3042/Customer/CustomerDetails.aspx only?
In my immediate window I get the following:
?DirectCast(Me.FindControl("txtFName"), TextBox).Text.ToString().Trim()
Referenced object has a value of 'Nothing'.
?txtFName.Text
"Lisa"
So .. if I take out the DirectCast syntax, the value is passed but with DirectCast I get the Referenced Object has a value of nothing .. why and do I even need DirectCast here?
