Editing In Place Using Templates

For columns belonging to the TemplateColumn class, you can define a special template that is applied when one cell of such a column is being edited. In previous examples, I built a templated column that displayed data obtained by merging the first and last names with the title of courtesy. When you need to edit the content of a heterogeneous column like that, provide a template that includes each input control. For example, you might want a drop-down list supplying all the possible values for the titleofcourtesy column. You also must use separate text boxes for the first and last names. The following code creates a possible edit template:

 <edititemtemplate>     <asp:dropdownlist runat="server" id="ddTitles"  ...
