index: Item index in the control

index2: Additional index for some controls. In a ListView control it defines the column.

fmt: Object with format information

Create a DataBind link for one item. The item is added to the refresh group and the internal callback handler will write new values to the specified control at the specified index. The value is formatted according the format definition object.
DataBind.ApplyChanges() must be called for the added links to be activated in the server. This is to increase performance by activating multple links with a single server access.
