using a query string to pass a hyperlinkfield value to another page

[dougancil]

I have a page with a gridview and I want to pass the value when a user clicks on a hyperlinked field in the grid to another page. Here is the code for the gridview:

<asp:GridView ID="GridView1" runat="server" HorizontalAlign="Center" 
            AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
            <Columns>
                <asp:BoundField DataField="SchedName" HeaderText="SchedName" 
                    SortExpression="SchedName" />
                <asp:BoundField DataField="ActivityDate" HeaderText="ActivityDate" 
                    ReadOnly="True" SortExpression="ActivityDate" />
                <asp:BoundField DataField="By" HeaderText="By" SortExpression="By" />
                <asp:BoundField DataField="Activity" HeaderText="Activity" ReadOnly="True" 
                    SortExpression="Activity" />
                <asp:BoundField DataField="FirstListing" HeaderText="FirstListing" 
                    SortExpression="FirstListing" />
                <asp:HyperLinkField DataTextField="OnCallStart" HeaderText="OncallStart" 
                    NavigateUrl="\website1\Default2.aspx" SortExpression="OnCallStart" />
                <asp:BoundField DataField="OnCallEnd" HeaderText="OnCallEnd" ReadOnly="True" 
                    SortExpression="OnCallEnd" />
            </Columns>
        </asp:GridView>
 

and when a user clicks on the OncallStart field, I want to pass the values of whatever is in that field to the next page. Can someone give me an example of how to do that?

Thank you

I receive the following error when I try to pass values between web pages:

Literal content ('<asp:HyperLinkField DataTextField="OnCallStart" HeaderText="OncallStart"
NavigateUrl="\website1\default2.aspx" SortExpression="OnCallStart" DataNavigateUrlFormatString=”default.aspx?oncallst art={0}"/>') is not allowed within a 'System.Web.UI.WebControls.DataControlFieldCollect ion'. Can someone please help me to pass values between 2 pages? I've read several forums and this seems to be the way to go but I can't make it work.

Thank you

Doug

During the GridView's OnRowDataBound Event, set the URL of the HyperLink to include Query String parameters that you require in order to pass info to the second page.
