Question

var conString = ConfigurationManager.ConnectionStrings["CONSTRING"].ConnectionString;
SqlConnection con = new SqlConnection(conString);
string uname = Session["un"].ToString();
Label sid = (Label)DetailsView1.Rows[1].Cells[1].Controls[0].FindControl("lblsid");
TextBox nam = (TextBox)DetailsView1.Rows[2].Cells[1].Controls[0].FindControl("lblname");
TextBox lnam = (TextBox)DetailsView1.Rows[3].Cells[1].Controls[0].FindControl("lbllname");
TextBox cont = (TextBox)DetailsView1.Rows[4].Cells[1].Controls[0].FindControl("lblcon");
TextBox ei = (TextBox)DetailsView1.Rows[5].Cells[1].Controls[0].FindControl("lblei");
TextBox add = (TextBox)DetailsView1.Rows[6].Cells[1].Controls[0].FindControl("lbladd");
TextBox cit = (TextBox)DetailsView1.Rows[7].Cells[1].Controls[0].FindControl("lblcit");
DropDownList typ = (DropDownList)DetailsView1.Rows[8].Cells[1].Controls[0].FindControl("lbltyp");
cmd.Connection = con;
cmd.CommandText = "update seller set  fname ='" + nam.Text + "',  lname ='" + lnam.Text + "', contact ='" + cont.Text + "', address ='" + add.Text + "', city ='" + cit.Text + "', type='" + typ.SelectedValue + "' where sid=" + sid.Text + "";
cmd.Connection.Open();

cmd.ExecuteNonQuery();

DetailsView1.ChangeMode(DetailsViewMode.ReadOnly);
BindData();

我知道这种方法是找到控件但我不知道如何在查询中传递Sid值。有人可以帮忙吗？在C＃上工作

使用参数。下面我告诉你如何为名字这样做。你可以这样做。

    body.bg {
    	background-size: cover;
    	background-repeat: no-repeat;
    	min-height: 100vh;
    	background: white url(http://lorempixel.com/output/city-q-c-1920-1080-7.jpg) center center no-repeat;
    	-webkit-background-size: cover;
    	-moz-background-size: cover;
    	-o-background-size: cover;
    }

如何在字段内传递标签值
