    Hello, my project has a custom GridView control (inherited from GridView)
    that uses TemplateFields to dynamically add controls based on meta data.
    Since they aren't BoundFields I am now having to set DataFormatString on
    each individual control but some controls dont have this option. For
    DropDownList (and other ListControls) I have DataTextFormatString, but for
    textbox and Label, etc i dont know how to set the format string.

    for example, i have a textbox that when shown in read mode should show only
    the date component of a datetime, so i want to do something like this
    {0:MM/dd/yyyy} but dont know how

  2. Hi TS,

    From your description you have a TextBox in ItemTemplate of the GridView
    that shows a date field and want to format the text, right? If so I think
    you can try this:

    <asp:TextBox ID="TextBox1" runat="server"
    Text='<%#DateFormat(Eval("theDate")) %>'></asp:TextBox>

    protected string DateFormat(object input)
    DateTime dt = DateTime.Parse(input.ToString());
    string output = dt.ToString("MM/dd/yyyy");
    return output;

    Please have a try and let me know if it works.

    thanks Allen, I found a different way to handle that in the binding method I
    override in gridViewTemplate.
