MVC :: Comparing An Input Field Against A Database Table?
Dec 6, 2010
I am REALLY new to ASP.NET MVC, and it is alien to my way of thinking.In my project, I have managed to get as far as allowing the user to add, edit or delete entries from a table. What I want to do is ensure that a specific field (i.e. "Tank_Number") does not get duplicated. What is the correct way to implement this?
I would like to use custom validation in the model class, the reason being the handy error messages, but am getting more confused as I read more articles. At the moment, I am using an If statement in the Controller, but it isn't ideal.
Here is my example code:
Controller [Code]....
Model
[Code]....
View
[Code]....

I would like a situation where there are three textbox available and this would give the user an opportunity to input a value in the textboxes. The value in the textboxes would then be stored in a database table(the table is already created in sql). Furthermore, the value would be able to be reterieved later on when the user presses another button. A sample code will help.

I have a form that contains a text box called "MyDate" in which the user enters a date. I have a table that contains records of which one of the fields in the record is a date field named "DateAvailable" (type is "datetime"). I want to compare the data in the text box to the "DateAvailable" field in record. How do I define my text box as a "datetime" field.

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

I need to select a field value from a database table. If the value read is '1' then I need a 'Y' to display as output in the select statement. I haven't figured out how to do this yet and queries I tried that did not work.
select IsIata from Table_1 CASE WHEN (IsIata = '1') THEN 'Y'
select IsIata CASE WHEN (IsIata = '1') THEN 'Y' from Table_1

I have a large database of user profile data. I need to be able to compare 1 row against all of the other rows, for all columns to find the best match.There are around 30 columns of data for each row. I need to be able to find the 5 best matching rows.
I.E.
Row 1 matches on 2 column's
Row 2 matches on 12 column's
Row 3 matches on 7 column's
Row 4 matches on 4 column's
Row 5 matches on 9 column's
Row 6 matches on 23 column's
Row 7 matches on 29 column's
In the end it will show me the data for rows 7, 6, 2, 5, 3 Now to make it even harder, Some of the columns are bit, some are varchar.Some of them may be a direct match, some will need to search if the column for row2 contains the text of row 1.

I'm writing an ASP.net website and have come across a problem which looks simple but I can't find the right syntax to make it work.
After a users log on I want to then point them to a page which is dictated by their presence in a project table.
I have created the table with the user names and userIds in
I have written some of the code but need advice on the bit which compares agaist the table.
Label.Text = Membership.GetUser().ProviderUserKey.ToString (this works fine)
Then I want to say something like:
If Label1.text is in Project table then Goto ProjectPage.aspx
Else Goto NonProjectPAge.aspx

I have created a basic website using ASP.net VB in order to display a diary of various user inputs to a website, I have created a register page, home page and once the user logs in it will direct them to a user logged in page where the diary entries that they have been created or been added to are displayed from the built in SQL database. I am trying to work with roles to ensure that when a certain login user is logged it will link them to a certain page (sort of like a basic admin page, but really its just to link to a page that only they can see).
I have used a session variable to take the username input and to display the diary entries they are linked to. How can I use another session variable to compare the role of the user that is logged in to allow me to direct them to the webpage that should link to their role. I have written code on the .aspx.vb that I thought would have worked, but it complies fine but doesn't work correctly. How can I write the code so that when the person inputs their details in, it would compare the username/password then to the role that they have been associated with in the database (these areas are all in the same table) that will then link to the webpage.
This is the error message I get on running the login page.Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.

I have a gridview, which on the row data bound method that inserts a row when comparing values on a particular field. If the two values are different, a new row is inserted, if not no row is inserted. This coding is working as a grouping gridview, and is working correctly. However, I have problem, and problem is counting the rows between each group, which I want to display in my blank row between each group, the value of which I am holding in a hiddenfield.
When I try to do it, the first group doesn't show the result, but is displayed on the next group. I am pretty sure that I am doing something wrong. My approach is that if the value between the last row and the existing row are different, then the value is one, on the next row data bound event, if the values are the same then the value is increased by one, else the value is one because it is a new group. Here is my code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
Table tbl = e.Row.Parent as Table;
TableCell cell = new TableCell();
CheckBox chk = new CheckBox();
Label lbl2 = new Label();
HiddenField rowValue = new HiddenField();
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Visible = false;
}
else
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Session["count"] = 1;
Label lbl = (Label)e.Row.FindControl("lblValue");
string str1 = ((Label)(lbl)).Text;
string prevStr= (string)Session["previousStr"];
if (prevStr== str1)
{
lbl.Visible = false;...................

For this applications, I will have a table that has a list of users who are "moderators" and they are able to see a part of the website that regular users cannot. I will NOT have a login or anything like that - I have a table that lists all the users who are moderators and if the user who is logged in is a moderator they simply see more of the website.
Right now I am able to get the username of the logged user (these are users who log into a Windows machine, and I simply get their login using a method from System.Security).
The thing I have no idea how to do is actually compare the username to the username in the database that I have. can anyone point me to a tutorial or something that searches through a database to compare the given value and see if there is an identical one in a specific database? I don't want the user to see the database, this is all done "behind the scenes".

On my DetailsView for inserting, I have a field "manager code". When the user types in the code, I want another field "manager name" to be populated based on a lookup table in the database. I have done this on a FormView using code behind and "ontextchanged". How can I do this in DetailsView?

Simple question. I have the following hidden input field on my ASP.NET page:
<form id="userform" method="post" action="RankingPage.aspx">
<input type="hidden" id="email" />
<input type="hidden" id="name" />
</form>
I'm trying to get the data from the field (in my code behind) like this:
protected void Page_Load(object sender, EventArgs e)
{
string name = Request.Form["name"].ToString();
}
It's returning a null reference (which I'm assuming means it couldn't find the field). Am I doing this wrong?
