EmployeesRow object and return the number of days the employee has been employed as a string. This method can be added to the ASP. NET page's code-behind class, but must be marked as protected or public in order to be accessible from the template.
To utilize this method we need to invoke it from a TemplateField in the GridView using the databinding syntax. Its Row property returns the strongly-typed Northwind. This databinding syntax can appear directly in the ItemTemplate as shown in the declarative syntax below or can be assigned to the Text property of a Label Web control.
However, the Eval method returns an object , so we'd have to change our DisplayDaysOnJob method signature to accept an input parameter of type object , instead. Therefore, we'd need to accept an object as the input parameter for the DisplayDaysOnJob method, check to see if it had a database NULL value which can be accomplished using Convert. Due to these subtleties, I've opted to pass in the entire EmployeesRow instance.
In the next tutorial we'll see a more fitting example for using the Eval "columnName" syntax for passing an input parameter into a formatting method. The TemplateField in the GridView control allows for a higher degree of flexibility in displaying data than is available with the other field controls.
TemplateFields are ideal for situations where:. In addition to customizing the display of data, TemplateFields are also used for customizing the user interfaces used for editing and inserting data, as we'll see in future tutorials. The next two tutorials continue exploring templates, starting with a look at using TemplateFields in a DetailsView.
Following that, we'll turn to the FormView, which uses templates in lieu of fields to provide greater flexibility in the layout and structure of the data.
