I have a small web app that displays data from a SQL Server database. Using
a DataGrid control on a page, the user can delete a row from the database.
This works fine. But I want to prompt the user for confirmation ("Are you
sure...") before deleting the record. How can I do this from the ASP.NET
code? Since the C# code is server-side, is there a way to display a Yes/No
type of message box and only take action if the users clicks the "Yes"
button? I'm new to web development, so any and all help is appreciated.
Here is the deletion message handler; I want to prompt the user for
confirmation before the deletion code executes:
private void dgridProfiles_D elete(object source,
System.Web.UI.W ebControls.Data GridCommandEven tArgs e)
{
[** How do I prompt the user here??]
[If user said yes, then...]
String profID = e.Item.Cells[0].Text.Trim();
String deleteCmd = "DELETE from Profile where ProfileID = @profID";
string connstr =
ConfigurationSe ttings.AppSetti ngs["BLConnectionSt ring"];
SqlConnection connection = new SqlConnection(c onnstr);
SqlCommand myCommand = new SqlCommand(dele teCmd, connection);
myCommand.Param eters.Add(new SqlParameter("@ profID", SqlDbType.Char,
10));
myCommand.Param eters["@profID"].Value =
dgridProfiles.D ataKeys[(int)e.Item.Ite mIndex];
connection.Open ();
try
{
myCommand.Execu teNonQuery();
dgridProfiles.E ditItemIndex = -1;
LabelMessageAre a.Text = "Profile deleted.";
}
catch (SqlException )
{
LabelMessageAre a.Text = "ERROR: Could not delete record.";
}
finally
{
connection.Clos e();
}
BindGrid();
}
[end code sample]
Thanks!

I have a <a href="javascript:top.window.close()"><img src="exit.gif"></a>
tag on my page that closes itself when you click on it.
What I NEED is for it to put up a confirmation message that simply asks
"This will end your session and close the window", then offers a cancel or
ok button. Clicking on ok closes both the page it was on, and the
confirmation window.
Can someone suggest a simple way to do this?

Hi. On my online ordering form I use browser cookies to keep track of
user items. My confirmation page reads:
"If any of this information is incorrect, please go back to the order
form and change it. We thank you for your patronage.".
Question. At what point will I be able to delete my cookies? If I
delete them before posting the online form, then they won't be available
if customers from the confirmation page.

Hi All,
I am trying to understand the blocking method socket.Send().
The call blocks as expected, but does this mean, it returnes after the
underlying TCP layer got a confirmation, that the send data was received by
the socket on the remote end? Can I count on that? Do I understand TCP
correctly in that, it gives confirmation ? I do not
expect, that a .Net based receiver got that data when socket.Send()
terminates!

Hi,
I want to have confirmation(Yes/No) on a button of the webform in which
there are many validation controls. I want all the validation controls to be
triggered first and then Yes/No confirmation message. By adding just an
confirm attribute for 'onclick' event of the button doesn't work with
validation controls. Is there any short way to go around this.
Thanks

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
