Is having a trigger that inserts a row in Table 'A', when a row in same table is inserted by ADo.Net code?
I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a s...

Adding table rows to a table in an update panel
I'm trying to add table rows to a table that has already been added to the update panel (ie, in design view).
When I run my code, the text changes on the page, but I dont get additional rows, its as if its forgetting about the first row that was already added and simply over writing it...
Anyone got any thoughts? I had a label in there before where I'd reference the label and add text to the existing text, that worked fine, the text that was already there just stayed and the dialogue got longer etc, why is it different with the table rows?
Any help would be appreciated..Rega...

adding html table columns from SQL table rows
I want to put data from an SQL table into an HTML table, but I want to start a new row in the HTML table when it is 5 columns wide. I have done this in classic ASP with the following code:

How can I accomplish the same thing with asp.net? I have created my SqlDataSource and the SelectCommand no problem, but I'm kind of stuck how to loop through the recordset.
