Hi,

Use like this on Row Command Button,

CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />

And then,  In code behind,

 protected void grdexam_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "dtls") 
        {

            int index = int.Parse(e.CommandArgument.ToString());
            Label paperid = (Label)grdexam.Rows[index].FindControl("Label1");
            Label subject = (Label)grdexam.Rows[index].FindControl("testname");
            SqlCommand cmd = new SqlCommand("select * from ExamMaster where groupid='" + Session["grpid"] + "' and papercode='" + paperid.Text + "'", con);
            SqlDataAdapter adp = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            adp.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                GridView1.DataSource = dt;
                GridView1.DataBind();
                pnlsubbjectiv.Visible = true;
            }
            else 
            {
                Response.Write("wromg");
            }
        }
    }

Hi,

Try something like this.

protected void gridMembersList_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "Add") // Or something
{

int index = Convert.ToInt32(e.CommandArgument.ToString());
Literal ltrlslno = (Literal)gridMembersList.Rows[index].FindControl("ltrlSlno");
Literal ltrlName = (Literal)gridMembersList.Rows[index].FindControl("ltrlName"); Session["ltrlName "] = ltrlName.Text;

}

}
