typically, a login page takes the redirect page on the URL. And you'd store the cart contents in a cookie or the session, if they are logged in, or not.

Do it now. You'll see that CP does exactly what I was talking about. It redirects to the login page and passes to the login page, the page to go back to, on the URL. So, once you login, it reads that value and navigates back to that page.

Hi mates,

Need help again. About adding textbox value in gridview footer template, would it be possible? How will i do that? Note: The textbox value is come from the maxid of sql query. When the gridview page will load, it should have initial value one of the textbox.

<ItemTemplate>
<asp:Label ID="lblUserId" Text='<%# Eval("UserID") %>' runat="server"></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblUserId" Text='<%# Eval("UserID") %>' runat="server"></asp:Label>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtUserId" Text='' runat="server"></asp:TextBox>
</FooterTemplate>

Updating drop-downlist boxes corresponding to values selected in the other drop-down list

Hi....I have two drop-down List boxes.How to update one drop-down list box based on values of other drop-down list..

E.g: Drop-down list 1 contains cars like Toyota,Hyundai etc...
If Toyota is Selected
(drop-down list 2 it must be updated with models of Toyota)
else Hyundai is selected
(drop-down list 2 must be updated with models of Hyundai)

All these data must be taken from SQL server

I am able to display the drop-down list 1 but i am not sure how to display only corresponding models of the selected Make(drop-down list1)

Why is this asked so often when it's so trivial ?

1 - handle the changed event of the first list
2 - in the event, read the value, and use it to populate the second list

Well, typically, there is an id stored as a value for the first list, so you end up with something like

select * from model where makeID = @makeId

as a stored proc which you call using the id from the selected column.

This can also be done with AJAX. You have the user-facing page, an AJAX script, and a dynamic page. The user's selection passes a value over an XmlHttp request to a dynamic page, the output is returned via XmlHttp, and the contents of the user-facing page are changed via Javascript. Check out this example which has samples of all three parts-

Good luck!

Sure - it's almost the canonical AJAX example. I was just trying not to confuse the guy tho.

Auto Email Send

Hello
SQL Server Databse keeps order information.
I want to send an automatic email to customer if order has been placed.
Any Solution

Thanks

Yeah, the solution would be to automatically send an email when the order is placed. Might want to do that somewhere around your insert statement in your code, since that's probably where the order is complete in your end.

Christian Graus2-Feb-09 8:16

Did you consider trying to write some code to do this ? I don't see what SQL Server has to do with it.

It is difficult and complicated to setup SQL database triggers to send email when the database is updated. You would also have to run a local SMTP server on the SQL server which is often discouraged. The best thing to do would have your code update the SQL database, check to see if it was successful, and then use the SmtpMail class to send mail-

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...) is the synatax from w3schools.com[^]

is Create your table name?

try putting insert into `create` (...) values(...)

example

INSERT INTO `Persons` (P_Id, LastName, FirstName)
VALUES (5, 'Tjessem', 'Jakob')

What is name, city, etc ? Where do they come from ? It looks to me like your database security is a nightmare.

"Create" is a reserved word in MSSQL so it cannot be used as the name of a table. Here is a full list of reserved words:

You should be able to insert into the table by quoting the table name like so:

INSERT INTO "Create" ...
