I use repeater in my asp.net application to display records from database. The datasource that binded to 开发者_运维技巧repeater are records of a datatable.

How can I get one column value for an item in repeater's itemdatabound event?

I want to get a value of column called 'id'. How to get it in the repeater_itemdatabound event in backend?

In the Repeaters ItemDataBound event, you can extract the object bound to the item via the e.Item.DataItem property, and do:

var item = e.Item.DataItem as MyObject;
if (item.ID > 0)
   //Do something

In the item databound event you have access to the event arguments (variable e) e.Item.DataItem is the record that is currently being bound. Be sure to cast it as a DataRow or whatever the type is of the item in the collection being bound.

You could access the ID column

    Dim dr As System.Data.DataRow = DirectCast(e.Item.DataItem, System.Data.DataRow)
    Dim id As Int64 = dr("ID")
