ASP.net gridview evaluating datafield after each record - asp.net

Question

Hey all i am wondering if it was possible to evaluate the datafield each time it places a new record into a row?
my gridview code is this:
<asp:Panel ID="pnlGrid" runat="server">
<div class="left_main_container" style="margin-bottom:20px;">
<asp:GridView ID="grdView" runat="server" CssClass="GridViewStyle"
AutoGenerateColumns="False" GridLines="None" Width="100%">
<Columns>
<asp:BoundField DataField="id" Visible="False" />
<asp:BoundField DataField="theName" HeaderText="Name" />
<asp:BoundField DataField="status" HeaderText="Status" />
</Columns>
<RowStyle CssClass="RowStyle" />
<EmptyDataRowStyle CssClass="EmptyRowStyle" />
<PagerStyle CssClass="PagerStyle" />
<SelectedRowStyle CssClass="SelectedRowStyle" />
<HeaderStyle CssClass="HeaderStyle" />
<EditRowStyle CssClass="EditRowStyle" />
<AlternatingRowStyle CssClass="AltRowStyle" />
</asp:GridView>
</div>
</asp:Panel>
The field i need to evaluate is status. I need to find out if the status is yes or if its no. If its no then i need to make it a link for the user to be able to change it to a yes.
The gridview is populated by this code:
Dim objConn As MySqlConnection
Dim objCmd As MySqlCommand
objConn = New MySqlConnection(strConnString)
objConn.Open()
Dim strSQL As String
strSQL = "SELECT id, status, " & _
"CONCAT(' ', first_name, last_name) AS theName " & _
"FROM(builder_requests) " & _
"ORDER BY status, id DESC;"
Dim dtReader As MySqlDataReader
objCmd = New MySqlCommand(strSQL, objConn)
dtReader = objCmd.ExecuteReader()
grdView.DataSource = dtReader
grdView.DataBind()
dtReader.Close()
dtReader = Nothing
objConn.Close()
objConn = Nothing
Any help would be great!

I like to use a TemplateField and a function in your code-behind to do this sort of thing.
I am assuming your status field is a string field not boolean but if not let me know and I can adjust the example.
Replace your BoundField with...
Markup:
<asp:TemplateField>
<ItemTemplate>
<%# Eval("status")%>
<asp:LinkButton ID="cmdChangeStatus" runat="server" CommandName="ChangeStatusToYes" CommandArgument='<%# Eval("id") %>'
Visible='<%# SetChangeStatusVisibility(Eval("status")) %>'>Change to Yes</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
And add code behind function...
Code:
Protected Function SetChangeStatusVisibility(status As Object) As String
Dim strStatus As String = status.ToString()
If strStatus = "no" Then
Return "True"
Else
Return "False"
End If
End Function
Then you can handle the GridView.RowCommand event to change the status value based on the id value in CommandArgument :)
