什么是Container.DataItem？

解决方法

So what is this expression exactly? The <%# %> means this is a
DataBinding expression and Container.DataItem is an alias for the
current item in the datasource. In other words,if you are binding to
a collection of objects Container.DataItem is the current row of that
collection.

Container.DataItem is a runtime alias for the DataItem for this
specific item in the bound list. For a grid which displays 10 rows of
data,this is one row from the datasource. The actual type of
DataItem is determined by the type of the datasource. For example,if
the datasource is a Dataview,the type of DataItem is DaTarowView. If
the type of the datasource is an array of strings,the type of
DataItem is String. If the datasource is a collection of
strongly-typed objects (for example “Employees” objects),the type of
DataItem is Employees.

Each of these cases requires a slightly different databinding expression,with further differences between VB and C#.
