A one-tier implementation is self-contained. It combines presentation, business, and data services.
Ex:
A stand alone PC running Microsoft Access.
A mainframe with attached one or more dummy terminals. A dummy terminal is just a physical point of contact with the mainframe.

Sir,
My application is running on intranet. Around 25 computers are accessing the application simultaneously.Now the problem is when simultaneously more then one user is trying to update the single particular record , Then the database will select which new entry to update.I mean when a request is send to update the database .That particular record should be locked so that it can't be updated at that very time by another user.
Please help.
Thanks

Will ROWLOCK option of database row locking work for you?
OR Is it possible for you to use synclock of .NET

If your stored procedure checks for the previous values for the existing record, it will only allow the first item to update the record. Subsequent updates will not happen unless the item is refreshed from the database. Check to see if the item was updated. If not, display a message to the user, and refresh the view.

Hi,
I've written a simple page where the user inputs data and then hits a submit button. It's a server button control and has code behind.
This is the odd part...
It never works when I just run the page without breakpoints in the code. There is no exception. The breakpoints SOMETIME work and when they do the code works.
Even when the code for the button works (when I step through it), the onClientClick event doesn't seem to fire.
Any help would be appreciated!
Thanks,
Peter

The OnClientClick property is used for events handled in the browser (i.e. Javascript), not on the server.
---
b { font-weight: normal; }

onClientClick is javascript, correct? If so, it's a client side event, and no postback is performed, thus missing the break point.

You should be able to use SelectedIndexChanged event on dropdown1 and on the eventhandler of that, you can fill records in dropdown2.
protected void myDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
//Write code to fill dropdown2 based on value selected in dropdown1
}

:-OI have a datagrid column which goes as -
<asp:templatecolumn headertext="New Inquiry Type">
<itemtemplate>
<asp:hyperlink id="hplnkInquiryType" runat="Server" text="<%#DataBinder.Eval(Container.DataItem,"investor" name").tostring()%="">>
when i try to view the page in the design mode i get this error --
Could not open in Design View . Place quotes around a '<% %>' block used as an attribute value or within a element.
it works when i wrap the text attribute within 2 single quotes -
but then the Hyperlink on the datagrid throws an error when clicked as - undefined
i.e. coz it needs the investor_name to be wrapped around single quotes.
thus the hyperlink works with the following code but no design view --

Use the "Ignore HTML" option when you post HTML code.
---
b { font-weight: normal; }
|
|
|
|
|
ASPX code seems to be missing. click "Ignore HTML tags in this message (good for code snippets)".
You also may want to wrap it in a <PRE> tag

i created an user control, it has 3 properties, but when i add to web page , i cannot see its properties at property window why ?
|
|
|
|
|
|
For a user control the properties are not shown in the Property window. Instead you must create a custom control. Just google for "create custom control" and you'll find a lot of tutorials.

a user controls are already custom controls.

You're wrong about that. They're two different things. I suggest reading this[^]
