View 4 RepliesIf I have records in a table in this order:
Id - Date - Type

Can I somehow select the records between a record having type 1 and type -1 without using a cursor,for example the records with ids 1-4 in this example?
I want to limit the selecting of data records to only the user who created the record, OR a users who's email address belongs to the domain of the record being edited. So, if the producer has a value in the URL of "[URL]" and their email address in the Membership is [URL] they will be able to see the record.
I have the following table:
Table - Producer
Field: ProducerID
Field: ItemUserID
Field: URL
I have figured out how to select based on the ItemUserID (see code below), but I don't know how to compair the email address values of URL and the Membership.
protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
if (Page.User.Identity.IsAuthenticated)
{
//get id of user logged in
e.Command.Parameters["@ItemUserID"].Value = Membership.GetUser().ProviderUserKey;
}
}
how to code my requirements?
I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.

I have two tables. One table containing 1 master record and the other table containing multiple records per 1 master record. I want to only display in a gridview (or whatever is best) the master record AND its assocated detail records IF certain fields in the detail records are there. I have been trying to figure out how to do this but I am still a bit of a newbie and I don't how I can do this.

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that
does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification
and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....
