<h2>Purpose</h2>
|
|
|
|
<p>
|
|
This example demonstrates how to use the <b>QuantumGrid4</b> (or <b>QuantumGrid5</b>)
|
|
product from Developer Express (contact <b>www.devexpress.com</b>. for
|
|
licensing
|
|
information if you do not already have the product).

Things to look at in QuantumGrid4_server.exe
|
|
</p>
|
|
<p>
|
|
The most important methods in the host application are in the <b>NewService_Impl</b>
|
|
unit:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
<b>GetCustomers</b> retrieves all the records from that dataset.
|
|
</li>
|
|
<li class="contents">
|
|
<strong>GetOrders </strong>only retrieves Orders for the current Customer.
|
|
Note the parameters passed to it.
|
|
</li>
|
|
</ul>
|
|
<p class="h2">
|
|
Things to look at in QuantumGrid4_client.exe
|
|
</p>
|
|
<p>
|
|
There's only two lines of code in <b>QuantumGrid4_ClientMain</b>, one for each button.
|
|
</p>
|
|
<p>
|
|
Have a look at <b>QuantumGrid4_ClientData</b> though. This contains code that
|
|
saves references to customers previously accessed, thus avoiding re-fetching details.
