Hi,

This is the content of an aspx file: ('dat' is a date field in a table)
<asp:BoundField DataField="dat"
DataFormatString="{0:dd-MM-yy}"
HtmlEncode="false" />
<asp:CommandField ShowEditButton="True"/>

What i want to know is how to set the property 'DataFormatString' directly in VB.net and how to program 'ShowEditButton="True"' (in the code-behind page aspx.vb) instead of like here?

Thanks

I could already do this:
Dim obj As DataControlField
obj = GridView1.Columns.Item(0)
response.write(obj)

This gives "CommandField"
(Item(1) gives "BoundField")

But now, i'm stuck ...
