Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

I have enabled User Rolls and assigned several Roll names such as 10, 11, 12, etc. I have a SQL Table that contains various fields of information including one named AuthorizedUserRoll, it's nchar(2).
A logged in user should only see the records in Gridview that matches his/her roll.
I'm using Web Forms and VB.

What I'm trying to do is to pull this data from a database, through LINQ.
However, on the next code behind page, when I type merchantid2.Text it doesn't work.
How do I get the value back from the cs code behind page, if it's already been displayed on the aspx?
<td>
<asp:Label
runat="server"
ID="merchantid2"
Text='<%# Eval("m.merchantname")%>'></asp:Label>
</td>

I have a remove hyperlink which is created in a literal and I want it to post some data (a number in a text box). I think this should be possible but when a user clicks the remove link I want to be able to pick up what is in some text boxes. So in short existing click triggers postback, so I can use request.form("txt1")

I have a requirement to log all/most forms authentication transactions that take place within my page. For example, if someone is kicked out because of forms authentication, I'd like to get their username, time when kicked off, and where this happened. Is there a good way to do this. Better yet, has anyone done this already and is willing to share some code or post a link?

I have a strange situation.An ASP.NET button click event causes an object in memory to be updated. The object was loaded from NHibernate via Refresh() during Page_Load, but at no time during the entire page life cycle is Commit() or Flush() called.At some point after the page's OnUnload step, the object and any changes made to it are automatically persisted to the database. I cannot see when or where or why this occurs.

I have this page in my application that contains a couple of grids and a few text boxes. Now these grids are getting populated from a hidden field in the page. My requirement is like the main page should have an "Update All" button where as these grids have their individual Update and delete options. Now when I delete or update anything from the Grids it should do a soft update or delete function and eventually when I hit "Update All" an actual commit statement should be executed.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
begin
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
TextBox PhoneNo = (TextBox)row.FindControl("TextBox2");

All I am trying to do is to make an update to an existing User and then save the changes to the database. I fooled around with different options and can see that I can make the change to the context during Page_Load, but it does not commit the changes to the Database.

i am using the transaction-per-request (session-in-view) pattern for an asp.net web application. I have a couple of points in the application where i want to Save an NHibernate managed entity and then do a couple of more inserts and updates using common sql. These inserts/updates depend on the ID that the NH saved entity will take.
The problem is that the generated id does not exist in the transactions' scope. If i force a flush/commit the id is persisted but if the inserts/updates fail i have to rollback but the flushed/committed entity will not. Currently I'm doing a manual insert for these cases but that is something i want to change. So, is there a way to execute the SQL statement (inside the already open transaction) after the Save() but without forcing a flush/commit?
EDIT: I'm adding a semi-pseudocode example, i got 4 wrong answers so i think people don't understand (how NHibernate works)
At the Begin request i issue a
nhsession.BeginTransaction()
then at some point i do
FooClass fc = new FooClass("value");
nhsession.Save(fc);
ITransaction trans = nhsession.Transaction;
SqlCommand sc = new SqlCommand("some insert/update query that depends on fc's id", (SqlConnection)nhsession.Connection);
sc.Parameters.Add("id", fc.Id); //NHibernate generates the id, note i'm using assigned/hi-lo so no round trip to the db takes place
transaction.Enlist(sc);
try {
sc.ExecuteNonQuery();
}
catch (SqlException ex){
transaction.RollBack();
nhsession.Close();
}
and at the end of the Request i issue a CommitTransaction() and nhsession.Close()
Now this will do absolutely nothing: the FooClass (fc) has not been flushed/commited to the database. The Save() operation that NH has done is up to that point in-memory. That means no sql command has been issued by nhibernate and that means that the SqlCommand (sc) that i fire afterwards will fail miserably as the id does not exist.
If i do a flush/commit between Save() and the SqlCommand the FooClass(fc) _cannot_be_rolled_back_ and that is a bad bad thing.Currently, for this to work i make vanila sql insert using an SqlCommand, and i want to change that. (Why? because i don't want to make vanilla inserts they are susceptible to errors due to schema/model changes, and i got the OR/M for that)
How? i want to notify NHibernate somehow to execute the SqlCommand to corresponds to the Save() insert (hell, it can do all the SqlCommands it has gathered) but without it commiting or flushing!.
Currently i'm also searching for the prepared sql statement that nhibernate produces when flushing/commiting a saved object. Maybe i can just take that string and run it in my SqlCommand that is enlisted in the Transaction.

I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
protected void Page_Load(object sender, EventArgs e)
{
try
{
...do something here...
}
catch (ArgumentNullException ae)
{
System.Diagnostics.Debug.Write(ae.Message);
Label1.Text = ae.Message;
Label1.Style.Add("visibility", "visible");
}
catch (Exception ex)
{
...do something here...
}
}
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)............................
