setting default value in detailsview template

[miketayloruk]

I'm using a detailsview control that I want to use to insert data to a
table. One of the fields is a date field and I want that to default to
todays date. In classic asp I would do it like this:

<input name="textfield " type="text" value="<%=now() %>" />

How do I do this in ASP.NET, heere is my current code:

<asp:DetailsVie w ID="DetailsView 1" runat="server"
AllowPaging="Tr ue" AutoGenerateRow s="False" DataKeyNames="d ata_key"
DataSourceID="S qlDataSource1" Height="50px" Width="125px">
<Fields>
<asp:TemplateFi eld HeaderText="dat a_key"
InsertVisible=" False" SortExpression= "data_key">
<InsertItemTemp late>
<asp:TextBox ID="TextBox1" runat="server"
Text='<%# Bind("data_date ") %>'></asp:TextBox>
</InsertItemTempl ate>
</asp:TemplateFie ld>
<asp:BoundFie ld DataField="data _comment"
HeaderText="dat a_comment" SortExpression= "data_comme nt" />
<asp:CommandFie ld ShowDeleteButto n="True"
ShowEditButton= "True" ShowInsertButto n="True" />
</Fields>
</asp:DetailsView >

Thanks
