i am making a webform for university students to register projects.there is a dropdown list which will ask how many students have participated, suppose student select 3 students, now my question is how can i restrict user to enter only one students data,i want he/she should fill all three students data than the submit button should enabled.
View 5 RepliesIn my website there is 1 module in which i m fetching data(Student name, Roll no.) of students from the student master table into gridview... and in that gridview there is 1 checkbox column...
I want that when i will check the checkbox of those students who are present...dat checked students and name should be get entered into another table in database where there wil be present written in front of checked students and absent written in front of unchecked students.....
I tried a lot but I am not getting it.....
From the above table(student info) i wil fetch data in gridview and will mark attendance in the gridview
In the above sample gridview in the student name column the name of the students is fetched from student info table, when I will check the checkbox and select the date and click on the button the students who are checked will be stored with a status present and those who are unchecked are stored as absent in another table
The following is the table(example) is where the data is to be stored in the same manner. It means that total two tables are there in the database.
From 1 table i fetch data of students info in gridview and in another table i wil save the attendance marked in gridview....
I have a combo box that looks great in the designer, the list of choices are perfect. But when I view the ASP code, or the published webpage the choices are seriously garbled. I have tried adding items, but it does not seem to regenerate the code. Any ideas why it happened and what I should do? I do most of my editing through the designer GUI. Note the blank items and even items mixed up together: TVCricket
asp Code:
<asp:DropDownList ID="ddlFoundOut" runat="server"> <asp:ListItem Selected="True">(Pick how you found out about us)</asp:ListItem> <asp:ListItem>Another Store</asp:ListItem> <asp:ListItem>Banner at Arena</asp:ListItem> <asp:ListItem>TVCricket</asp:ListItem> <asp:ListItem>West NewsmagazineClear</asp:ListItem> <asp:ListItem>Driving By</asp:ListItem> <asp:ListItem>Friend/Co-worker</asp:ListItem> <asp:ListItem>Internet</asp:ListItem> <asp:ListItem>Mall Sign</asp:ListItem> <asp:ListItem>Online Phone Book</asp:ListItem> <asp:ListItem>Phonebook (paper)</asp:ListItem> <asp:ListItem>Radio</asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem>Other</asp:ListItem> <asp:ListItem>Other Magazine</asp:ListItem> <asp:ListItem>Other News Paper</asp:ListItem></asp:DropDownList>
That out of the way, here's my situation: We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app.
I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation.
Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
I wonder how they build visit conters that can be used on more tha one page?
View 1 RepliesI have a general question regarding usercontrols' parameters. In the built in web controls, such as the 'runat' parameter, when you begin to type 'runat' in Visual Studio, it gives you an Intellisense choice of 'server'. Or in the RequiredFieldValidator controls, the 'Display' parameter has 3 choices: Dynamic, None, and Static.
My question is, how do I incorporate this feature into my custom Usercontrols?
For instance, I created a usercontrol with a parameter called 'BorderColor'. This parameter will change a textbox's border color to the specified value. The possible values are: Blue, Red, Green, Black, Purple, etc. How do I have Intellisense display these choices when the BorderColor parameter is typed in?
I am working on an ASP.net Forms Application that keeps track of information about different offices in an organization. The offices are organized into a hierarchy.
Some users of the program will have access to certain information about all offices in the hierarchy. Some users of the program will have access to only a small part of the hierarchy.
When a user browses for information they are authorized to see, I would like to present the user with a prompt to choose which office in the hierarchy they wish to see information from.
I want to accomplish the following:
A) I want the user to be able to easily navigate the hierarchy of the organization to locate a specific office.
B) I want the user to be able to navigate the hierarchy without refreshing the page.
C) I want my interface to be able to handle a hierarchy at least four layers deep with less than 100 nodes.
I see that Microsoft includes a TreeView control in the standard collection of ASP web controls.
I am searching for a combobox like control but where a tree will be shown in the dropdown(instead of a list) and multiple choices have to be possible.
I have thought of implementing this [URL] in combination with a jquery dropdown button but it will be alot of work to get there.
I have an asp.net web site with 10-25k visitors a day (peaks of over 60k before holidays). Pages/visit is also high, since it's a content site. I have a few specific pages which generate about 60% of the traffic. These pages are a bit complex and are DB heavy (sql server 2008 r2 backend). I was wondering if it's worth "caching" a static version of these pages (I hear this is possible) and only re-render them when something changes (about once in 48hs). Does this sound like a good idea? Where would be the best place to implement this? (asp.net, iis, db) Update: Looks like a good option for me is outputcache with SqlDependency. I see a reference to some kind of SQL server notification for invalidating the cache, but I only see talk of SQL server 2005. Has this option been deprecated by Microsoft? Any new way to handle this?
View 2 RepliesI've built a Repository that gets user details
Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID
Dim user = (From u In dc.Users
Where u.OpenID = openid
Select u).FirstOrDefault
Return user
End Function
And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null.
What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit?
I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside.
Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState
If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then
Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository
Dim _user As New UrbanNow.Core.User
_user = repo.GetUserByOpenID(User.Identity.Name)
Session("UserName") = _user.UserName()
Session("UserID") = _user.ID
End If
End Sub

View 2 RepliesI'm not expecting a full solution here (unless you really want to), just some tips and pointers.
I have a User table and an Area table. The User table has userID, userName etc., and the Area table has areaID, areaName etc.
I'm binding the list of Areas to a checkboxlist where the user MUST choose between 1-3 options. I'm using a stored procedure to update the DB.
Is there a common solution to this problem that I haven't found?
I have thought about saving it as a comma separated string in a field in the user table. This looks like a temporary and ugly solution though, do you think?
A nicer solution would be to create a UserArea table where I save the ID's as foreign keys from areaID and userID. But I don't know how to write this stored procedure where I update and insert the choices made.
I am using AppCode and have 6 arrays of information I want to display on my web page. However I only want three to be visible at any one time.

i.e. a table like the above.
I have created the layout and the choice buttons etc I am using querystrings to pass the changes to the webpage.
The problem comes however when trying to write the code for the table diplay. Now each has a slightly different layout.
My initial thought was to write a function within the aspx/html page for each table, then in each column of the master table one of the functions can be called to populate it. Each of the functions will contain the HTML tagging for that information. However I dont seem to be able to achieve this as when I try to right a sub or function it doesn't like it. I have also tried to write the functions into the code behing but again this didnt work.
I have a website which contains several ajax enabled pages. I need to maintain state in each page. I have added historypoints in each page. My back button works fine as far as I am on single page. But when I visit different page and then click back button to come to original page, only the last history state for that page is loaded and all other seem to get wiped out. What I mean is, clicking back button again takes me to previous page instead of loading same page again from history point. Is there any way to maintain history points even when I visit different pages
View 4 RepliesI work in a multi server , multi webfarm environment (without sessions). We need to be able to identfy if a customer has arrived here for the first or has been before (even though they have not logged in)Not only will we change the text of our salutations depeding on this state but we will also use it in other busness logic. I can check for the existance of a cookie when they fire the Session_onStart event but I would have to write a cookie out to show they had previously visited for the next time the customer came to call.
If I wrote the cookie out in the Session_onStart then somehow I would have to tell the website that this was a first time visit. Also as this is a stateless webfarm - the next server may be different from the previous one which would fire a new Session_onStart event in its own right - which would see the cookie and assume it was not my first visit, even though it was my first visit on a different web page of the web site.
I dont want to write it out and say if its within X minutes of the cookie creation time you are still in your first visit as that x minutes wouldnt work 100% of the time If I dont write the cookie out on Session_onStart then when could I write it out?
I have a problem i want to check when prospect visit the website and see what page they link at in c#.

View 5 RepliesI want to bind a field in a View to a property in a ViewModel. The object is "Program" and has the properties "Name" and "Level". So the user should be able to set the name of a program and the level of experience he/she has with this program.Program is a table in an Sql Server database, and is accessed through Entity Framework. So it would be easy enough to bind the Level property in the ViewModel to a textbox:
@Html.TextBoxFor(model => model.Level)
But I want a dropdownlist with a limited number of levels (1-5). So how do I do this and still have the dropdownlist bind to the ViewModel property?
If I want to be able to have a table Consultant, which is the user and their personal information, and I want this user to be able to select their proficiency in a number of Programs (software) on a scale from 0-5 (zero being no experience whatsoever), how do I do this best?
I mean I could have a Consultant table with a one-to-many relationship to a Program table, and then have all the limited Programs availalbe loaded by an XML file or something, and for each Consultant associate all the Programs and their Levels of proficiency. But that seems very wrong and inefficient.
It seems to me I should have a table with all the (limited number of) Programs, and then by some sort of association between the two by Ids. But I can't get my head around how to do this. I'm thinking many-to-many... But first, is this correct? Secondly, how do I do this in an Entity Framework Model? I usually create my database code first, i.e. create the EF model, and then generate database from model. Will I get a junction table where I can add the Level field, because basically a Consultant HAS A Program with a Level, or actually a list of Programs each with a Level.
Just trying to figure out a basic script for the following Contact Us form.

5.Comments
I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices, based off of that enum. But I'd like it to pull records from a database and populate the list of choices for the property from a database. This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.
View 3 RepliesSay that, there is a login.aspx page for any application. I would like to see this login page in different format if user visit by Iphone or any other mobile device. I have already designed two different page for test purposes. If i visit the page which is modified for Iphone, everything works fine.
what is the best way to switch between these two page depends on by which device user visit? These two pages could be even totally different two pages like black and white because of page layout issues.
Currently, I'm just using clientside Javascript (location.href), but I am wondering if there is a way in Asp.Net to figure out the URL the user originally entered (assume I did not change it myself via 301), or at least to track it in a simple and reliable manner. As I am using my own implementation of URL rewriting via the global.asax (e.g. Context.RewritePath), this is not an easy task, particularly since I don't want to touch it too much.
Example
Global.asax:
public override void Init()
{
base.Init();
this.BeginRequest += new EventHandler(Global_BeginRequest);
}
void Global_BeginRequest(object sender, EventArgs e)
{
if (VARIOUSCONDITIONS) Context.RewritePath("SOMEURL");
}
SomePage.aspx.cs
protected void Page_Init(object sender, EventArgs e)
{
//Request.RawUrl is equal to "SOMEURL", as
//are other properties that store the URL.
}
