    <p>Please see following methods.</p> <pre><code> public static ProductsCollection GetDummyData(int? customerId, int? supplierId) { try { if (customerId != null &amp;&amp; customerId &gt; 0) { Filter.Add(Customres.CustomerId == customerId); } if (supplierId != null &amp;&amp; supplierId &gt; 0) { Filter.Add(Suppliers.SupplierId == supplierId); } ProductsCollection products = new ProductsCollection(); products.FetchData(Filter); return products; } catch { throw; } } public static ProductsCollection GetDummyData(int? customerId) { return ProductsCollection GetDummyData(customerId, (int?)null); } public static ProductsCollection GetDummyData() { return ProductsCollection GetDummyData((int?)null); } </code></pre> <p>1- Please advice how can I make overloads for both CustomerId and SupplierId because only one overload can be created with GetDummyData(int? ). Should I add another argument to mention that first argument is CustomerId or SupplierId for example GetDummyData(int?, string). OR should I use enum as 2nd argument and mention that first argument is CustoemId or SupplierId.</p> <p>2- Is this condition is correct or just checking > 0 is sufficient -> if (customerId != null &amp;&amp; customerId > 0)</p> <p>3- Using Try/catch like this is correct?</p> <p>4- Passing (int?)null is correct or any other better approach.</p> <p><strong>Edit:</strong></p> <p>I have found some other posts like this and because I have no knowledge of Generics that is why I am facing this problem. Am I right? Following is the post.</p> <p><strong><a href="https://stackoverflow.com/questions/422625/overloaded-method-calling-overloaded-method">Overloaded method calling overloaded method</a></strong></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
