Extract Day, Month, Year from Databound Date into DropDownLists
Posted on 2006-07-14
I want to let users update their "Birthdate" using drop-down lists. The "Birthdate" is stored as smalldatetime in SQL Server 2005 Express, and I am using a Formview for updates.
The problem I have is that I don't know how to extract the Month, Day, and Year from the date and use them to get the selected values from three dropdownlists (For Month, Day, Year). For Inserting new records, it's no big deal, since I can make the entire date from the dropdown fields. However, when I display the Update page, I want the user's birthdate to already be selected in the dropdowlists so he/she doesn't have to input it again.
I was thinking I could have the 3 dropdownlists with the "SelectedValue" property bound to the "Birthdate" and then trim off parts of the date. For example using: <%# LEFT(DataBinder.Eval(Container.DataItem, "BirthDate"),2) %> to get the month. But this only works for double digit months.
Thanks in advance.
