I have the default "Enable Editing" check  on the GV.

When a user clicks on the "Edit" for a row, I need to have one of the
columns set to a value which is stored in a QueryString.

After the "Edit" button is clicked I can set the TextBox value as desired,
however, after clicking "Update" the changes are not posted to either the GV
nor the database.

Here is what I have currently.

<asp:TemplateField HeaderText="modifiedby" SortExpression="modifiedby">
<EditItemTemplate>
<asp:TextBox ID="tbEditItemModifiedBy" runat="server" ReadOnly="false"
Text='<%# Request.QueryString("userid").ToString()%>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="tbItemModifiedBy" runat="server" Text='<%# Bind("modifiedby")
%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>

I am able to "Edit" other values and are saved accordingly. I am having the
problem whey I try to dynamically update values on the fly.

TIA,

Steve
