I’ve been struggling with this issue for a whole day now and I don’t seem to find an answer.
I have a page called PickRecord.aspx where I have dynamically generated columns “Start Interview”, “Edit” and “View Record” which will redirect me to the StartInterview.aspx or EditViewInterview.aspx accordingly.
PickRecord.aspx – The GridView is populated with Interviewee names and a button is generated which when clicked on should redirect me to StartInterview.aspx and give me other fields/information in the record selected.
StartInterview.aspx – Contains additional information on the record chosen which needs to be populated with data from the database. I have tried query string, used selectedIndexChanged and had no luck.
Woul’d really appreciate it if somebody can guide me through this. Thanks in advance!
PickRecord.aspx
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Height="470px" Width="660px" HorizontalAlign="Center" SelectedIndexChanged="GridView1_SelectedIndexChanged">

<asp:BoundField DataField="Last_Name" HeaderText=" Last Name" ItemStyle-HorizontalAlign = "Center" >
</asp:BoundField>
<asp:BoundField DataField="Salon_Number" HeaderText="Salon" ItemStyle-HorizontalAlign = "Center" >
</asp:BoundField>
</Columns>

You haven’t mentioned the exact issue, but if you are not even hitting StartInterview.aspx page then I would advice you to remove the complicated instantiated in code and replace it with a simple template based column having a button or even a button column. You can check this link for the implementation : Redirect to specific page when a gridview buttonfield is clicked
