Hi,
I have Customer class with the following properties:

Customer
- CustomerID
- CustomerName
- CustomerLastName

I have bind list of customer to dropdownlist with DataTextField as CustomerName, and DataValueField as CustomerID.

Now when I am selecting customer from dropdown i want CustomerLastName for some other operation.
So how can access CustomerLastName using ASP.Net and C#

Thanks,
Parimal

Solution 2

When the CustomerID is unique you can get the CustomerLastName by the CustomerID.
How you do that in the end depends on how you store the data, can you give me details about the database system you are using? Or are you using a file to store the customers?

I am using sql server 2008.

Then you can get the Customer by its ID on the SelectedIndexChanged event of the dropdown, and then read the CustomerLastName from the corresponding property.

Hope I could help ya,
cheers
