i would like to ask about the design pattern of insert/update/delete record in the datagrid.

but when clicking the save/update/delete button, how can i write a good progrmming pattern to perform this action.
any example code for my reference?
I have a series of record IDs in an array that I pass to a DataGrid for Data Binding I want to show the details of each record ID in every row of the datagrid, for example I can put a detailsview in the itemtemplate of the datagrid and use an objectdatasource's select method for retrieving the information for a specific record ID but how to pass these record IDs to objectdatasource? is this a correct example and how can I implement this?
View 3 Repliesi cannot retrieve the new identity value from an inserted record(via DataAdapter.Update) in my DataRow.
I'm using a strong typed Dataset as DAL. The table i want to update is joinded with other tables in the SelectCommand, hence the designer cannot automatically generate the insert-/update-/delete-commands and also it cannot "Refresh the DataTable" automatically. [URL]
I've tried to set AutoIncrement=true/false on the primary-key's DataColumn but the result is the same: last MAX-ID+1 instead of the actual ID the database generated(SQL-Server 2005 EP; pk datatype:int, Is identity:yes, Identity Increment:1).
This will be the wrong value f.e if another instance of the application inserted a record that the first instance yet not knows and therefore generates an ID that already exists.
To retrieve the new identity from db i've appended following to my insert-command's CommandText:
;SELECT CAST (SCOPE_IDENTITY() AS int) AS newIdRMA
Also i've tried to add an Output-Parameter to it's parameter-collection:
This is part of my code that updates the database and sets the new ID(that doesn't work):
[code]...
DataClasses1DataContext dc = new DataClasses1DataContext();
var q =
from a in dc.GetTable<Order>()
where a.CustomerID.StartsWith("A")
select a;
}
i have run this query but through using dataGridView1.DataSource = q;

i have a website that needs to retrive some records in the database, to be specific, example is their Email Address, its more or less 10 records out of 100 records in a table but that number changes from time to time. upon retriving their Email Address, i need to Email them some messages one email at a time.
So to summarized it all:
1. Retrive data from a table (Email Address)
2. Make a Loop on each Email then send Message one email at a time.
give me a sample codes for the retriving and looping process?

I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection.
I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?
