get rowid in gridview

I have a gridview and want to capture the rowid so I can pass it as a parameter in a query string. Below is my code thus far and it is only working for the first row and not the others rows.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            CellPadding="4" DataKeyNames="ReqId" DataSourceID="SqlDataSource1" 
            ForeColor="#333333" GridLines="None" AllowPaging="True" 
            AllowSorting="True" 
            OnSelectedIndexChanged="GridView1_SelectedIndexChanged" 
            onpageindexchanged="GridView1_PageIndexChanged" 
            >
            <RowStyle BackColor="#EFF3FB" />
            <Columns>
                <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="ReqId" HeaderText="Requisition Id" 
                    SortExpression="ReqId" Visible="true" />
 
 
<asp:LinkButton ID="lnkbtnChangeReq" runat="server" 
                onclick="lnkbtnChangeReq_Click">Change Requisition</asp:LinkButton>
 
 
protected void lnkbtnChangeReq_Click(object sender, EventArgs e)
    {
        //GridView1
        string rowId = GridView1.DataKeys[0].Value.ToString();
        //try to prevent url tampering
        Random random = new Random();
        int num = random.Next(1000); //random number that means nothing
        string strq = "m"; //modify for close of req
        //build querystring
        string url = "updaterequisition.aspx?";
        url += "rid=" + rowId + "&";
        url += "svd=" + num + "&";
        url += "sr=" + strq;
        Response.Redirect(url);
    }

look at the ItemDataBound event. You can use e.Row to build the link reference when the grid is being bound.

Is "lnkbtnChangeReq" defined inside the GridView or outside?

jinal

First my question lnkbtnChangeReq is out side GridView or inside grdiview.

1. IF out side.

protected void lnkbtnChangeReq_Click(object sender, EventArgs e)
    {
        //GridView1
        string rowId = GridView1.DataKeys[GridView1.SelectedRow.RowIndex].Value.ToString();
        //try to prevent url tampering
        Random random = new Random();
        int num = random.Next(1000); //random number that means nothing
        string strq = "m"; //modify for close of req
        //build querystring
        string url = "updaterequisition.aspx?";
        url += "rid=" + rowId + "&";
        url += "svd=" + num + "&";
        url += "sr=" + strq;
        Response.Redirect(url);
    }

Here is what you need to do:

protected void lnkbtnChangeReq_Click(object sender, EventArgs e)
    {
        //GridView1
        GridViewRow row = (GridViewRow)(sender.NamingContainer);
        string rowId = GridView1.DataKeys[row.RowIndex].Value.ToString();
        //try to prevent url tampering
        Random random = new Random();
        int num = random.Next(1000); //random number that means nothing
        string strq = "m"; //modify for close of req
        //build querystring
        string url = "updaterequisition.aspx?";
        url += "rid=" + rowId + "&";
        url += "svd=" + num + "&";
        url += "sr=" + strq;
        Response.Redirect(url);
    }
