Remarks
Use the Row property to programmatically access the FormViewRow object that represents the data row. The data row contains different content based on the template rendered for the current mode (specified by the CurrentMode property). You can only access the contents of the template for the current mode. The following table shows which template is used for each mode.
| Mode | Template rendered |
|---|---|
| Edit | EditItemTemplate |
| Insert | InsertItemTemplate |
| Read-only | ItemTemplate |
Note
The Row property is available only after the FormView control creates the data row in the ItemCreated event.
This property is commonly used when you need to programmatically manipulate the data row, for example when adding custom content. Any modification to the Row property must be performed after the FormView control has been data-bound; otherwise, the FormView control overwrites any changes.
