    if (e.CommandName == "_Approve")
    {
        //using (SqlConnection con = DataAccess.GetConnected())
        using (SqlConnection con = 
                 new SqlConnection(ConfigurationManager.ConnectionStrings["mydms"].ConnectionString))
        {
            try
            {
                int rowindex = Convert.ToInt32(e.CommandArgument);
                GridViewRow row = (GridViewRow)     

            ((Control)e.CommandSource).NamingContainer;
                LinkButton Prove_Button =   
               (LinkButton)row.FindControl("BtnApprove");
                SqlCommand cmd = new SqlCommand("spinsertapprove", con);
                cmd.CommandType = CommandType.StoredProcedure;
                int result = cmd.ExecuteNonQuery();
                if (result != 0)
                {
                    GrdFileApprove.DataBind();
                }
            }

            catch 
            {
                apfi.Text = "Not Approve";
            }
            finally
            {
                con.Close();
            }
        }
    }


    else if (e.CommandName == "_Reject")
    {
        using (SqlConnection con = 
                    new SqlConnection(ConfigurationManager.ConnectionStrings["mydms"].ConnectionString))
        {
            try
            {
                int rowindex = Convert.ToInt32(e.CommandArgument);
                GridViewRow row = (GridViewRow)
                ((Control)e.CommandSource).NamingContainer;
                LinkButton Prove_Button = (LinkButton)row.FindControl("Button1");
                SqlCommand cmd = new SqlCommand("sprejectapprove", con);
                cmd.CommandType = CommandType.StoredProcedure;
                int result = cmd.ExecuteNonQuery();
                if (result != 0)
                {
                    GrdFileApprove.DataBind();
                }
            }

            catch 
            {
                apfi.Text = "Rejct";
            }
            finally
            {
                con.Close();

您没有向 SQL 调用添加任何参数值，因此可能根本不会调用存储过程，因为您在定义上没有任何默认值。

您需要在调用之前为每个参数添加以下内容：

myCommand.Parameters.AddWithValue("@UserID", userId);
myCommand.Parameters.AddWithValue("@DocID", docId);
myCommand.Parameters.AddWithValue("@ApproveType", "Approve");

最后一个是：

myCommand.Parameters.AddWithValue("@ApproveType", "Reject");

对于拒绝案例。

这些值需要从它们存储的地方读取，而不是硬编码。
