请帮助，我已经在gridview中添加了更新/编辑命令按钮，以便更新我的sql server数据库中的数据，但我无法做到 . 数据未在数据库中更新 . ====== onrowupdate的代码======================================== protected void gRowUpdate（object sender，GridViewUpdateEventArgs e）{Books b = null; b =新书（）; DataTable dt = null; GridView g =（GridView）发送者;试试{dt = new DataTable（）; b =新书（）; b.author = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Author”））; b.bookID = Convert.ToInt32（g.Rows [e.RowIndex] .FindControl（“BookID”））; b.title = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Title”））; b.price = Convert.ToDouble（g.Rows [e.RowIndex] .FindControl（“Price”））; // b.rec = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Date_of_reciept”））; b.ed = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.bill = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.cre_by = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.src = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.pages = Convert.ToInt32（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.pub = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.mod_by = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.remark = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; // b.year = Convert.ToString（g.Rows [e.RowIndex] .FindControl（“Edition”））; b.updatebook（b）中; g.EditIndex = -1; dt = b.GetAllBooks（）; g.DataSource = dt; g.DataBind（）; } catch（Exception ex）{throw（ex）; } finally

} ===================我的存储过程更新书能够通过exec在sqlserver mgmt studio中更新数据库============== ============设置ANSI_NULLS ON设置QUOTED_IDENTIFIER ON

ALTER PROCEDURE [dbo] . [usp_updatebook] @bookid bigint，@ author varchar（50），@ title varchar（50），@ price bigint，@ src_equisition varchar（50），@ bill_no varchar（50），@ publisher varchar（50） ），@ pages bigint，@ redmark varchar（50），@ edit_var varchar（50），@ modified_by varchar（50）/ @ date_of_reciept datetime，@ year_of_publication datetime / AS声明@modified_on datetime

设置@ modified_on = getdate（）

更新书籍

组

author = @ author，title = @ title，price = @ price，

src_equisition = @ src_equisition，bill_no = @ bill_no，publisher = @ publisher，/ Date_of_reciept = @ date_of_reciept，/ pages = @ pages，remark = @ remark，edition = @ edition，/ Year_of_publication = @ year_of_publication，/

created_by = @ created_by，modified_on = @ modified_on，modified_by = @ modified_by

在哪里bookid = @ bookid ========================类库函数更新================ ====

public void updatebook(Books b)
    {
        DataAccess dbAccess = null;
        SqlCommand cmd = null;
        try
        {
            dbAccess = new DataAccess();
            cmd = dbAccess.GetSQLCommand("usp_updatebook", CommandType.StoredProcedure);
            cmd.Parameters.Add("@bookid", SqlDbType.VarChar, 50).Value = b.bookID;
            cmd.Parameters.Add("@author", SqlDbType.VarChar, 50).Value = b.author;
           cmd.Parameters.Add("@title", SqlDbType.VarChar, 50).Value = b.title;
            cmd.Parameters.Add("@price", SqlDbType.Money).Value = b.price;
            cmd.Parameters.Add("@publisher", SqlDbType.VarChar, 50).Value = b.pub;
          // cmd.Parameters.Add("@year_of_publication", SqlDbType.DateTime).Value =Convert.ToDateTime( b.year);
            cmd.Parameters.Add("@src_equisition", SqlDbType.VarChar, 50).Value = b.src;
            cmd.Parameters.Add("@bill_no", SqlDbType.VarChar, 50).Value = b.bill;
            cmd.Parameters.Add("@remark", SqlDbType.VarChar, 50).Value = b.remark;
            cmd.Parameters.Add("@pages", SqlDbType.Int).Value = b.pages;
            cmd.Parameters.Add("@edition", SqlDbType.VarChar, 50).Value = b.ed;
           // cmd.Parameters.Add("@date_of_reciept", SqlDbType.DateTime).Value = Convert.ToDateTime(b.rec);
            // cmd.Parameters.Add("@created_on", SqlDbType.DateTime).Value = Convert.ToDateTime(b.cre_on);
            cmd.Parameters.Add("@created_by", SqlDbType.VarChar, 50).Value = b.cre_by;
            //cmd.Parameters.Add("@modified_on", SqlDbType.DateTime).Value = Convert.ToDateTime(b.mod_on);
            cmd.Parameters.Add("@modified_by", SqlDbType.VarChar, 50).Value = b.mod_by;

            cmd.ExecuteNonQuery();

        }
        catch (Exception ex)
        {
            throw (ex);
        }
        finally
        {
            if (cmd.Connection != null && cmd.Connection.State == ConnectionState.Open)
                cmd.Connection.Close();
            dbAccess = null;
            cmd = null;
        }

}

我还尝试通过以下方式进行更新：protected void gv1_updating（object sender，GridViewUpdateEventArgs e）{GridView g =（GridView）sender; abc a = new abc（）; DataTable dt = new DataTable（）;尝试{

a.cd_Id = Convert.ToInt32(g.DataKeys[e.RowIndex].Values[0].ToString());
            //TextBox b = (TextBox)g.Rows[e.RowIndex].Cells[0].FindControl("cd_id");
            TextBox c = (TextBox)g.Rows[e.RowIndex].Cells[2].FindControl("cd_name");
            TextBox d = (TextBox)g.Rows[e.RowIndex].Cells[3].FindControl("version");
            TextBox f = (TextBox)g.Rows[e.RowIndex].Cells[4].FindControl("company");
            TextBox h = (TextBox)g.Rows[e.RowIndex].Cells[6].FindControl("created_by");
            TextBox i = (TextBox)g.Rows[e.RowIndex].Cells[8].FindControl("modified_by");

            //a.cd_Id = Convert.ToInt32(b.Text);
            a.cd_name = c.Text;
            a.ver = d.Text;
            a.comp = f.Text;
            a.cre_by = h.Text;
            a.mod_by = i.Text;
            a.updateDigi(a);
            g.EditIndex = -1;
            dt = a.GetAllDigi();
            g.DataSource = dt;
            g.DataBind();

        }
        catch(Exception ex)
        {
            throw (ex);
        }
        finally
        {
            dt = null;
            a = null;
            g = null;
        }



    }
