How can I modify a value before it is shown in a databound Repeater?

Question

I am databinding a repeater some text and a datetime(Respond By).

<asp:Repeater ID="rptList" OnItemDataBound="repeaterDatabound" runat="server">
     <HeaderTemplate>
     </HeaderTemplate>
     <ItemTemplate>
         <tr>
              <td>
                  <b>Respond By</b>
              </td>
              <td>
                  <%#Eval("RespondBy")%>
              </td>
          </tr>

Here I want to change the datatime before I display it on the screen, I want to do a rowdatabound similar to the one below. How can I do that for a repeater. Or is there anyother way of adding value(3Hrs) to Respond by dateTime before displaying it to users.

   protected void repeaterDatabound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DateTime.TryParse(Convert.ToString(DataBinder.Eval(e.Row.DataItem, "RespondBy")), out Respond);
        }
    }

I cant add 3hrs in the client side, the no of hours I have to add is different for each users,

What kind of manipulation are you trying to do? Is it nothing that could be accomplished with formatting or an addtional column in the datasource? — James Johnson, Nov 18 '11 at 15:55

You can either do following in aspx file.

 ((DateTime)Eval("RespondBy")).AddHours(3)

Or add a label/literal in aspx instead of <%#Eval("RespondBy")%> and use it in ItemDataBound

You could either change your <%#Eval("RespondBy)%> to some server control, a <asp:Literal> for example, then update the value of this in your ItemDataBound method.

Or you could use some inline code

<%#((DateTime) Eval("RespondBy")).AddHours(3).ToString("dd MMMM yyyy")%>

Or you could produce a public function which you can then reuse in the future.

public static string RespondByDate(DateTime theDate){
    return theDate.AddHours(3).ToString("dd MMMM yyyy");
}
