Setting default input values for an <InsertParameters> <asp:Parameter

[DC]

So I have a DetailsView that when I go into insert new mode I want each
field to have a default value. How do I go about this?

Ive tried

<InsertParameters>
<asparameter Name="ImageName" Type="String">noimage.gif</asparameter>
<asparameter Name="Title" Type="String">Dr</asparameter>
<asparameter Name="ForeName" Type="String">Forename</asparameter>
<asparameter Name="SurName" Type="String">Surname</asparameter>

But this throws up a "No lietrals allowed"

Ive also tried

<InsertParameters>
<asparameter Name="ImageName" Type="String" DefaultValue="noimage.gif" />
<asparameter Name="Title" Type="String" DefaultValue="Dr" />
<asparameter Name="ForeName" Type="String" DefaultValue="Forename" />
<asparameter Name="SurName" Type="String" DefaultValue="Surname" />

But this seems to have no effect whatsoever.

So how should I actualy be going about setting the initial values of the
bound fields when they go into edit mode?

Thanks in advance,
