I'm using a datalist that uses an item template to display results from an objectdatasource. The thing is, I'm only fetching a single record so a datalist doesn't seem like the best option. Is there a more suitable control I can use?
Also, how do I access the data on an objectdatasource that has been created in design view from code-behind. I've tried google but with no success.
On an ASP.NET page, I am using the same form for login and registration. There are two login fields and seven registration fields. Something like this:
txtUsername | txtPassword
txtNewUsername | txtNewPassword | txtNewPasswordRepeat | txtFirstName | txtLastName | txtPhone | txtEmail
btnSubmit
In each case, all the fields are compulsory (ie username and password are compulsory for logging in, and the other seven fields are compulsory for a new registration). There is a single submit button. This layout of the form is imposed by the client and is not open to modification.Now, my question is, how to validate the form? Initially, I cooked up a customized server-side validation system, but the client insists on using the standard asp.net validation controls (including the custom validator if necessary).
To validate the form, first I have to determine if the client is doing login or validation, and only then can I decide whether to validate one set of fields or another. So the first operation is to see if the user has filled in username or newUsername and use that to determine whether a login or a new registration is taking place. Since there is a single submit button, I cannot use validation groups to distinguish between the two sets of controls.
I thought about using a custom validator for the whole thing, but it is connected to a single control, so that does not solve the problem. I also thought about creating a new validation control, but again the problem is the same - any class inheriting from WebControls.BaseValidator is connected to a single form control.
How to Call a record on datalist by button click and display record on formview in model using Username
Here is what i tried
<asp:DataList ID="GetMergedAll." runat="server">
<asp:Label ID="Name" runat="server" Text="Label"></asp:Label>
<asp:Label ID="Post" runat="server" Text="Label"></asp:Label>
<asp:LinkButton ID="LinkButton6" runat="server">LinkButton</asp:LinkButton>
</asp:DataList>
protected void Page_Load(object sender, EventArgs e)
[Code] ....
HTML
model here
<asp:FormView ID="Post" runat="server">
<asp:Label ID="Name" runat="server" Text="Label"></asp:Label>
<asp:Label ID="Post" runat="server" Text="Label"></asp:Label>
</asp:FormView>
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Can anyone provide me with any alternatives here?

Over the last couple of weeks, i've been playing around with expression web to try and update our current company website: [URL]
Basically, our site is quite simple. We have individual product categories that are displayed and then the user can click through to view the individual product specification and pictures of said product.
I've created the category pages and inserted hyperlink fields to link to the individual product pages which works fine.
The problem i'm having is getting the specification and pictures to display on the product pages.
I'm literally tearing my hair out as i'm quite new to this.
The access database i'm using has the following fields, ProductID, CategoryID, Description, Comments (This is the Specification field) and then Image1, Image2, Image3 etc all the way up to image 10.
What i've been trying to do is to use an imagefield within a gridview to pull the Image name from the image fields and then display said images from the images folder. I have got this to work of a fashion, yet all the images are displaying instead of the particular product images only. I believe i need to add a query string to do this yet i'm totally at a loss as to how to set this up...
I'm also having the same problem with the specification (comments field) as i can't figure out how to only display the individual product spec..
In the stord procedure below. I am retreiving all the records for that 1 deal. What I want is to retrieve the most recent record hence the one with the most recent in the AddedDate field.
How can I accomplish this?

AS
SET NOCOUNT ON
SELECT deals_Comments.CommentID, deals_Comments.AddedDate, deals_Comments.UserID, deals_Comments.AddedByEmail, deals_Comments.AddedByIP, deals_Comments.DealID, deals_Comments.Body, deals_Comments.SBody,
ROW_NUMBER() OVER (ORDER BY deals_Comments.AddedDate DESC) AS RowNum
FROM deals_Comments
WHERE deals_Comments.DealID = @DealID

On a single page, I'd like to fill 2 hyperlink controls as well as a datalist control with table data using one call to the database. The page looks like this:
[Code]....
In the code-behind, I've tried several ways to accomplish filling the labels and the datalist with a single call but I can't make it happen without using either reader.read() or if (reader.read()) on the line before I make the call to fill the labels and the datalist. This fills the hyperlink controls correctly but advances the recordset forward by one, which results in the datalist missing it's first record.
I've tried using while (reader.read()), but I get an "invalid attempt to read when no data is present" error. I've also tried using if (reader.hasrows) but I get the same error as above.Here's an example of one of the 2 ways I can get the labels and the datalist filled with data, but again this advances the recordset forward and I end up missing the row of data:

I have a repeater control and a text box, and likewise a button to post data to database.after i insert the data to the database in thwe click event of the button, the datalist will not update the displayed content. at the end of the button's click even, i added the code line:
Response.Redirect(Request.RawUrl)
But still, the datalist will not update automatically. What do I do next?

I have a listview that has been constructed using tables. I have set the DataKeyNames="SomeTextField" among others. This column is currently not visible in the ListView.
I'd like to populate a textbox on the click of any listview record with the contents "SomeTextField" column.
Context: In an ASP.NET application, I need the behavior of the ItemTemplate / EditItemTemplate that the DataList control provides. However, I only need one item in my control, which makes the DataList seems like overkill.
Question: Is there a control in ASP.NET made to store a single item that has the template content behavior of the DataList and DataGrid? Should I use a DataList for only one item?
I populate my datalist with a function (watch below) but it jumps over my first db record.. Why is that??
