Basically you remove your <Asp:BoundColumn> columns and replace them with
<Asp:TemplateColumn> columns. A template column defines explicity what is
shown when in Item mode (not in edit mode) and when in Edit mode.
Normally every TemplateColumn has at the minimum an ItemTemplate and an
EditItemTemplate. If you ommit the EditItemTemplate you can make a column
read-only when in edit mode.
Here is a quick sample:
<ASP
ataGrid runat=server ... >
<COLUMNS>
<ASP:TEMPLATECOLUMN>
<ITEMTEMPLATE>
<asp:label id="lblItemCharge" Runat="server" CssClass="ChargeItem"><%#
Server.HtmlEncode(Container.DataItem("Charge")) %></asp:label>
</ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<asp:TextBox id=txtEditCharge Runat="server" CssClass="ChargeInput"
Text='<%# Container.DataItem("charge") %>' MaxLength="10"></asp:TextBox>
</EDITITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>
<ASP:TEMPLATECOLUMN>
repeat blah blah
</ASP:TEMPLATECOLUMN>
</COLUMNS>
</Asp
ataGrid>
