Body
<p>Base to Derived is possible(Boxing). But Derived to base gives run time exception, however that is equivalent to Unboxing. Why is it so </p> <pre><code>Base b = new Base(); Child c = new Child(); c = (child)b; // No compilation error but run time error object a; int i = (int)a; //No error Unboxing </code></pre> <p>Is it possible because object is top class all value type or Ref type inherited by Object class. public int ConvertToINT(object obj) { int i = (int)obj; return Convert.ToInt32(obj); }</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.
