Formatting DataBinder.Eval data

Question

How can I format data coming from a DataBinder.Eval statement in an ASPX page?

For example, I want to display the published date of the news items in a particular fo

Answer 1

There is an optional overload for DataBinder.Eval to supply formatting:

<%# DataBinder.Eval(Container.DataItem, "expression"[, "format"]) %>

The format parameter is a String value, using the value placeholder replacement syntax (called composite formatting) like this:

<asp:Label id="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate", "{0:ffffdd d MMMM}") %>'</label>

Answer 2

You can use a function into a repeater like you said, but notice that the DataBinder.Eval returns an object and you have to cast it to a DateTime.

You also can format your field inline:

<%# ((DateTime)DataBinder.Eval(Container.DataItem,"publishedDate")).ToString("yyyy-MMM-dd") %>

If you use ASP.NET 2.0 or newer you can write this as below:

<%# ((DateTime)Eval("publishedDate")).ToString("yyyy-MMM-dd") %>

Another option is to bind the value to label at OnItemDataBound event.

<asp:Label ID="ServiceBeginDate" runat="server" Text='<%# (DataBinder.Eval(Container.DataItem, "ServiceBeginDate", "{0:yyyy}") == "0001") ? "" : DataBinder.Eval(Container.DataItem, "ServiceBeginDate", "{0:MM/dd/yyyy}") %>'>
</asp:Label>

To format the date using the local date format use:
